ABSTRACT:
In tropical monsoonal climate rainfall is a seasonal phenomena. Further, features
of wet (or rainy) season such as starting date, ending date and duration show large spatial
and temporal variations. Very little effort is devoted to understand the nature of variation
of the wet season over and across the country. The present study attempts to document
climatological and fluctuation characteristics of the wet season over different basins as
well as the whole country using longest instrumental records.
Longest possible instrumental area-averaged monthly, seasonal (winter JF,
summer MAM, monsoon JJAS and post-monsoon OND) and annual rainfall series have
been developed for each of the 11 major and 36 minor basins as well as the west coast
drainage system of India using highly quality-controlled data from well spread network
of 316 raingauges. For the period 1901-2005 with complete data of all stations the
area-averaged series has been prepared from simple arithmetic mean of the gauges in the
particular basin, and for period prior to 1901 (sometimes going back to 1813) with
lesser observations the series is constructed by applying established objective method.
(Wigley et.al., 1984). Fluctuation characteristics of the annual rainfall over different
basins are briefly described.
Average standard deviation of interannual variation of the starting date is 10
days, that of ending date 14 days and that of duration 19 days. In majority of cases
probability distribution of the parameters of wet season is near-normal. Fluctuation of
parameters is homogeneous and random over all the basins.
1. INTRODUCTION
In recent years a new perspective has been added to hydrological investigations
of India with the launch of the most ambitious Master Plan 'Interbasin Water Transfer –
Interlinking of Rivers of India'. The plan is intended to utilize the country's water
resources to the fullest extent practicable by transferring water from the surplus basin to
deficit areas. One of the important issues to be addressed amicably in the planning
process of the program is the impact of global changes, particularly global warming, on
the rainfall fluctuation over different basins across the country. Basin-scale
characteristics of rainfall and wet season are expected to provide vital information to this
plan.
Surrounded between the parallels of 8°4′28″ N and 37°17′53″ N, and between the
meridians of 68°7′53″E and 97°24′47″E a beehive-shaped India occupies geographical
area of 3,287,263 sq. km. (including territorial sea) on the southern plank of the Asian
landmass. The contiguous land area of the country is 3,188,111 sq. km; its north-south
length is about 3,214 km and east-west breadth about 2,933 km. The land frontier is
15,200 km and the coastline 7516.5 km. Andaman and Nicobar Islands in the Bay of
Bengal and Lakshadweep in the Arabian Sea are parts of India. On the west of the
country are Pakistan and Afghanistan, on the east Bangladesh and Burma, on the north
Sinkiang province of China, Tibet, Nepal and Bhutan, and on the south Sri Lanka
separated by a narrow channel of sea formed by the Palk Strait and the Gulf of Mannar.
With three large watersheds, the Himalayas, the Vindhyas and the Western
Ghats, the country is drained by 11 major and 43 minor rivers and numerous rivulets.
Besides this in the West Coast Drainage system there are 25 small rivers that originate in
the Sahayadri range (Western Ghats) and discharge into the Arabian Sea (NATMO,
1996; Rao, 1975).
The climate of the country can be defined as tropical monsoonal characterized by
large seasonal extremes in circulation regime from cool, dry, continental winter
(frequently influenced by westerly waves and temperate fronts) during December
through February to hot, moist, maritime summer (frequently influenced by easterly
waves and tropical cyclones) during June through September caused by the south-north
migration of the main monsoon convection zone from its winter position over Indonesian
maritime continent to its summer position over head Bay of Bengal (extending over
Indo-Gangetic plains towards northwest India-Pakistan-Afghanistan-Iran sector) that
apparently follows the march of the sun through its Zenith in the torrid zone, between
tropics of Cancer (23.5°N) and Capricorn (23.5°S). The two boreal monsoons are mirror
image of each other. During winter sea level pressure is higher (1018 hPa) over northern
India compared to peninsula and adjoining sea (1012 hPa). Temperature at all levels
(surface to 300 hPa) over north is lower than that over peninsula. The prominent wind
direction over north is westerly/northwesterly/northerly and over peninsula northeasterly.
Opposite meteorological condition occurs during monsoon season. Sea level pressure is
lowest (994 hPa) over northwest India and high over peninsula (1010 hPa). Temperature
at all levels (surface to 300 hPa) is higher over north compared to peninsula. Westerly
1
and southwesterly are the prominent wind directions over peninsula and easterly over
Ganga plains. During transition seasons of March-April-May and October-NovemberDecember meteorological conditions are somewhat complex. Extreme weather events are
drought, flood, fog, smog, mist, frost, heat wave, cold wave, duststorm, thunderstorm,
hailstorm, cyclonic storm, tornado, storm surges etc.
Climate of the Indian subcontinent is dominated by the Indian Ocean southwest
monsoon. Derived from the Arabic word ‘Mausim’ (or ‘season of winds’) the monsoon
refers to system of winds that changes direction drastically from winter to summer
season. During boreal summer outflows from the southern hemisphere Mascarene High
pressure area into a bowl-shaped area of low pressure (monsoon trough) over IndoGangetic Plains are concentrated into a jet pattern, often called as a monsoon jet,
monsoon surge, a low-level jet, or a cross-equatorial jet. Moisture laden onshore
monsoon winds are about three miles thick. The rising air along the monsoon trough
diverges out of an upper-tropospheric (Tibetan) anticyclone along an upper-level jet-like
(easterly) flow. The monsoon trough is typically associated with low-level convergence,
cyclonic vorticity and cloudiness. Though monsoon is basic factor rainfall at a particular
location is a function of thickness of monsoon currents, convergence processes, regional
geography and orography. Rainfall shows large temporal variation at the same location.
To understand physical and dynamical causes of rainfall occurrences and their spatiotemporal variation is one of the main problems of the Indian meteorologists. High
quality-controlled, spatially detailed, long period rainfall data is vital for monsoon
studies.
Annual rainfall is less than 100 mm over parts of Ladakh (Jammu & Kashmir
State) and Jaisalmer district (Rajasthan State) and less than 400 mm over central
peninsula but it is between 1000 mm and 3207.8 mm (Dharamsala [Upper] station,
Kangra District), between 1000 mm and 1788.4 mm (Bhanupratappur station, Bastar
District) over central highlands and eastern plateau, between 1000 mm and 11405.8 mm
(Mawsynram station, East Khasi Hills District) over northeast, and between 1000 mm
and 7445.7 mm (Amboli station, Ratnagiri District) over Sahayadri range. The mean
annual rainfall of the whole country is 1165.9 mm of which 0.7% occurs during winter,
9.0% during summer, 77.4% during monsoon and 12.9% during post-monsoon.
Maximum temperature exceeds 50°C in extreme northwest India, 47.5°C over
Indo-Gangetic plains and central highlands, 40°C over northeast, 45-47.5°C along east
coast and 37.5-40°C along west coast. Lowest recorded minimum temperature is less
than -2.5°C over Thar Desert, Punjab and Haryana and it increases to 17.5°C in the east,
southeast and southwards. Annual potential evapotranspiration varies from about
1000 mm in the extreme northeast and western Himalaya to more than 2000 mm in the
extreme northwest. C. Warren Thornthwaite’s type climatic classification of the country
can be done using mean annual rainfall alone as: less than 560mm arid, 560-1040mm
semiarid, 1040-1420mm dry subhumid, 1420-1630mm moist subhumid, 1630-2450mm
humid and greater than 2450mm perhumid (Singh, 1984 and Singh et al, 1991
a). Twelve percent area of the country is arid, 37% semiarid, 28% dry subhumid,
9% moist subhumid, 9% humid and 5% perhumid. In other words 77% area with annual
rainfall less than 1420 mm is dry (evapotranspiration more than rainfall) and 33% with
rainfall more than 1420 mm is wet (rainfall more than evapotranspiration).

Due to large variation in intensity and frequency of rain-inducing disturbances
(western disturbances, thunderstorms, monsoon/cyclonic storms/depressions, monsoon
troughs etc.) and summer monsoon and post monsoon circulations over different parts of
the country rainfall occurrences exhibit large spatial variability. Hence areal
representation of the area averaged rainfall series for the whole country is limited. Spatial
variation in rainfall over India is quite large therefore temporal variation of area averaged
rainfall for the whole country is drastically suppressed. (Singh et al, 1991 b). The value
of the IAR (Index of areal representativeness), which is defined as the ratio of variance
of all India series and mean variance different series averaged and expressed in percent,
is only about 14% (Singh, 1994). The National Atlas & Thematic Mapping Organization
(NATMO, 1996) has published a map of India 'Drainage' on 'Conical Equal Area
Projection with two Standard Parallels' projection system and 1:6M scale showing
boundary of major and other basins (Figure 1). For the present report classification of the
country's river systems into major and minor basins by K. L. Rao (1975) is adopted.
Longest possible monthly, seasonal and annual rainfall series could be developed for
11 major basins, 36 minor basins and the west coast drainage system as well as the whole
country. Twenty seven of the 36 minor basins are the sub-basins of five major basins- the
Indus 3 (Chenab, Beas and Satluj), the Ganga 13 (Yamuna, Ramganga, Gomati,
Ghaghara, Gandak, Kosi, Mahananda, Chambal, Sind, Betwa, Ken, Tons and Son), the
Brahmaputra 3 (Tista, Brahmaputra and Dhansiri), the Godavari 5 (Wainganga,
Wardha, Penganga, Godavari and Indravati) and the Krishna 3 (Bhima, Krishna and
Tungabhadra). The other nine minor basins are Luni, Surma, Kasai, Damodar,
Suvarnarekha, Brahmani, Penner, Palar & Ponnaiyar and Vaigai. The Sabarmati, the
Mahi, the Narmada, the Tapi, the Mahanadi and the Cauvery are the major basins
without any distinct minor basin on the 1:6M scale map of India. In the present study
Sikkim State (7,096 sq. km2), Arunachal Pradesh State (83,743 sq. km2), Andaman &
Nicobar islands (8,249 sq. km2) and Lakshadweep islands (32 sq. km2) are not
considered because of non-availability of long period rainfall data. Thus the geographical
area of the country considered in the study is 3,188,111 sq. km2.
In tropical monsoonal climate understanding basin-scale variability of wet (or
rainy season) is as important as the variability of rainfall, very little attempt is made to
study the former compared to later. Identification of wet season in the annual weather
cycle is the crucial issue of the problem. Earlier attempts have been made to depict the
climatological summer monsoon (or rainy) season across the Asian monsoon region (Tao
and Chen, 1987; Tanaka, 1992; Lau and Yang, 1997; Wang, 1994; Wang and LinHo,
2002 and many others). Ananthakrishnan and Soman (1988) however identified yearwise
(1980) onset date of southwest monsoon over Kerala (India) by applying an objective
criterion to raingauge observations and studied variation and distribution characteristics
of the onset date. It is not known whether the criterion can be applied in reverse order to
obtain the withdrawal date. Further, this information is limited to Kerala. Singh (1986)
has applied an objective criterion ‘continuous period with each of the monthly rainfall
greater than 50mm’ to obtain start and cessation dates of normal rainy (or wet) season at
stations across India. The main objective of the present study is to apply this criterion to
area-averaged monthly rainfall data on interannual basis to document climatology and
fluctuation characteristics of the parameters of wet season (starting date, ending date and
duration) across different river basins of India using longest available instrumental
observations.

2. RAINFALL DATA USED
Instrumental monthly rainfall records from a well spread network of 316
raingauges (Figure 1) from earliest available year up to 2005 is used in preparing this
report. For all the 316 stations data is available for the period 1901-2005. Prior to 1901
number of available stations from this network decreases back in time- for 314
raingauges the data extend back to 1900, for 312 back to 1871, for 196 back to 1870, for
101 back to 1861, for 80 back to 1860, for 70 back to 1851, for 60 back to 1846, for
57 back to 1844, for 13 back to 1842, for 6 back to 1829, for 4 (Chennai, Mumbai, Pune
and Nagpur) back to 1826, for 2 (Chennai and Mumbai) back to 1817 and for sole station
Chennai back to 1813. Missing observation in the continuous data sequence has been
filled by the ratio method (Rainbird, 1967) using nearest available observation as
reference value. Number of filled values is less than 2% of the total number of monthly
rainfall records. Data up to 1900 is obtained from the India Meteorological Department
(IMD) publication ‘Monthly and Annual Rainfall of 457 Stations in India to the End of
1900’ (Eliot, 1902), and for the 1901-2005 period from the National Data Center and
Hydrology Section of the IMD, Pune. An account of this dataset is described by Mooley
and Parthasarathy (1984).
Blanford (1886) checked the reliability of data then available and concluded that
selected data were ‘free from any serious error’. In his attempt to compile and publish
rainfall data for all the gauges over British India up to 1900 AD, Eliot (1902) also
checked them thoroughly. Regarding reliability of rainfall data of the Indian region,
Walker (1910) had stated that ‘long established observatories like Madras (Chennai),
Bombay (Mumbai) and Calcutta (Kolkata) which have rainfall records available for
earlier periods in the nineteenth century are trustworthy’.
3. THE METHODS- DEVELOPMENT OF LONGEST RAINFALL SEQUENCE
The instrumental period area-averaged rainfall series is prepared in two parts,
(i) simple arithmetic mean for the period with all available observations from the
selected network and (ii) construction by applying established objective method for the
period with lesser available observations. The complete process is described step by step
for the Indus basin. Rainfall observation in the Indus basin started in 1844. In 1845
number of gauges increased to 2 which continued up to 1951, increased to 3 in 1952,
increased to 5 during 1853-54, decreased to 4 during 1855-56, increased to 6 in 1857, to
7 during 1858-59, to 8 during 1860-1861, to 9 during 1862-68, to 10 during 1860-70, to
16 during 1871-1900 and to 19 during 1901 and remained so since then. For creation of
longest area-averaged annual rainfall series for the basin the computational steps are as
(Singh, 1994; Sontakke and Singh, 1996; Wigley et al., 1984), follows,
1. Prepare the representative area-averaged annual rainfall series for the period
1901-2005 from simple arithmetic mean of observations from all the
19 raingauges in the basin;
(As indicated annual rainfall data of only 16 raingauges from the 19-gauge
network extends back to 1900, and the representative mean.)
4
2. Prepare the mean annual rainfall series of the 16 raingauges for the period
1901-2005;
3. Estimate the linear regression (Y = a + bX) of 19-gauge mean series {Yi} on the
16-gauge mean series {Xi} based on data of the period 1901-2000;
(All constructions in this report have been done with respect to the 'reference
period’ 1901-2000.)
Theoretically derived mathematical expression for the correlation (Rm,M) between
M-gauge mean rainfall series and m-gauge mean series (m is a subset of M) is given
by (Wigley et al., 1984):
R m, M =
m
1
s i ri , M
∑
m s(m) i =1
In the present example M is 19 and m is 16; s(m) is the standard deviation of the
16-gauge (here m = 16) mean series; si is the standard deviation of each of the
16 series; ri,M the correlation coefficient between each of the 16 gauge series and the
M-gauge mean series. The correlation coefficient directly calculated between
19-gauge mean series (Yi ) and the 16-gauge mean series (Xi) was equal to the Rm,M.
4. Substitute the mean rainfall of 16 gauges available during 1900 in the regression
and estimate the representative mean annual rainfall for the basin for the year
1900;
5. Inflate the variance of the estimated rainfall amount of the year 1900 by dividing
its departure from long term mean by correlation coefficient (r) between
19-gauge mean series (1901-2000) and the corresponding 16-gauge mean series
(Klein et al, 1959), and get the constructed mean annual rainfall of the Indus
basin for the year 1900;
6. Repeat the above process to estimate the rainfall of each of the four seasons
(winter JF, summer MAM, monsoon JJAS and post-monsoon OND) for the year
1900;
7. Check if total of the estimated four seasonal rainfalls is equal to the estimated
annual rainfall amount;
8. For any variation between the two figures proportionately increase/decrease the
seasonal rainfall amounts to get their finally constructed amounts; and
9. Estimate the monthly rainfalls in a similar, compare them with corresponding
constructed seasonal rainfall amount, and get the constructed monthly rainfalls
after suitable correction for the year 1900.
10. Take up the year 1899 and repeat the above process sequentially.
11. Then take the year 1898, 1897 and so on till 1844.
5
Theoretical details of the construction method are given in Wigley et al. (1984).
For pre-1901 period, the construction is retained if CC between all the gauges mean
series and limited available gauges mean series based on the period 1901-2000 is
significant at 5% level and above otherwise rejected. In the absence of anything this
instrumental data might provide vital information. The rainfall series for the basin could
be developed for the period 1844-2005. Similarly longest rainfall series have been
constructed for the other basins.
4. DEFINITION OF THE WET SEASON
Annual weather cycle at stations across India can be divided into two periods, dry
and wet. The wet period is also referred to as wet season or rainy season. Since the
terminology ‘rainy season’ is generally used for summer monsoon season we will use the
term ‘hydrological wet season’ that is continuous wet period irrespective of the
system(s) that bring the rainfall. Besides summer monsoon season, rainfall over
northwestern India occurs due to western disturbances, over northeastern India due to
thunderstorms during Mar-May, over extreme southwest due to thunderstorms in MarchMay and due to northeast monsoon during October-December, and over southeast mostly
due to northeast monsoon. While some parts of the country experience good rainfall
activities before and after the summer monsoon period, others experience rainfall during
peak period of the summer monsoon season, July-August. There are large variations in
the wet season (starting date, ending date and duration) across the country, and over the
same place from one year to another. In an earlier study the normal duration of wet
season at a station is identified as the continuous period with monthly rainfall greater
than 50mm (Singh, 1986). Over extreme southwest and the northeastern India the wet
season starts around 28th March and northwestern India around 28th July. Over most parts
of the country the starting date progressively shifts between these two extremes. The wet
season over the extreme southwest and northeast India starts much before the onset of
the southwest monsoon due to heavy and reliable rainfall activities associated with
thunderstorms. The late start over northwestern part is because of lesser rainfall activities
of the onset phase of the southwest monsoon over the region. Due to rain-shadow effect
for the southwest monsoon, the extreme southeast peninsula gets reliable rainfall only
during post-monsoon (or northeast monsoon) season and the date varies between
15th August and 10th October, from north to south. Being the area outside the monsoon
regime, Jammu and Kashmir gets rainfall from extra tropical systems like western
disturbances and trough in the westerlies. The season over the region starts between
20th December and the 1st week of January. The cessation date is especially more
consistant, organized and progressively shifting from northwest to southeast. The
extreme dates are 10th August for northwestern India and 10th January for southeastern
peninsula. For Jammu and Kashmir, the cessation date is 10th May. Consequently there is
large variation in the duration of the wet season over different parts of the country, about
20 days over northwestern India to exceeding 240 days over southwestern peninsula.
In the present study the criterion ‘continuous period with each of the monthly
rainfall greater than 50 mm’ is applied to monthly rainfall data of 11 major river basins,
6
36 minor basins, west coast drainage system and the whole country on interannual basis.
In the first month of the continuous period the starting date of the actual wet season is
determined by linear interpolation up to which, from the beginning of the month, 50 mm
rainfall is expected. And the ending date is determined in the last month of the period so
that between the linearly-interpolated date and the end of the month 50 mm rainfall is
expected to occur. Experiences suggest that occurrence probability of zero elements in
the monthly rainfall sequence whose mean is greater than 50 mm is almost nil. So in the
wet season one can expect some rainfall during every month. This report provides
documentation of statistics, distribution and fluctuation of starting date, ending date and
duration of the wet season over each of the river basins.
Limitation of application of the criterion should be borne in mind. The criterion
cannot be applied to interannual data of individual stations, particularly in arid and
semiarid regions in which in large number of years monthly rainfall may not exceed the
threshold of 50 mm. The criterion is however found applicable for area-averaged
monthly rainfall data of different spatial units’ viz. states, meteorological subdivisions,
physiographic regions and hydrologic river basins.
5. RESULTS AND DISCUSSIONS
5.1 FEATURES OF LONGEST ANNUAL RAINFALL SEQUENCE AND WET
SEASON OF DIFERENT BASINS AND THE WHOLE INDIA
The basins are arranged from north to northwest to northeast to south. The
description of the Indus, the Ganga, the Brahmaputra, the Godavari and the Krishna is
given first in order along with their minor basins. The remaining major basins are given
afterwards followed by independent minor basins. The West Coast Drainage System is
given thereafter. In the end description about the whole country longest rainfall series is
given as general information. The annual potential evapotranspiration (PE) reported here
is obtained from simple arithmetic mean of the stations in the particular basin. The
normal monthly and annual PE at stations across India is given in Rao et al (1971).
Number of rainy days (rainfall equal to or greater than 2.5mm) is extracted from IMD
publication ‘Monthly and Annual Normals of Rainfall and of Rainy Days’ (IMD, 1961).
The Indus Major Basin (drainage area: 291,749 km2; annual potential
evapotranspiration (PE): 1390.4 mm; mean annual rainfall: 860.3 mm- winter 10.5%,
summer 11.5%, monsoon 72.1% and post-monsoon 5.9% and annual rainy days: 41.6)The Indus rises in the Tibet near the Mansarovar Lake at an elevation of 5,180 m, passes
through northern Kashmir and Gilgit, enters Pakistan and emerges out of the hills near
Attock. The major tributaries are the Kabul, the Swat and the Kurram from the west and
the Jhelum, the Chenab, the Ravi, the Beas and the Satluz from the east. Earliest rainfall
record for Sirsa and Ferozepur is available from 1844. Data for all the 19 raingauge
stations of the selected network is available from 1901 onwards. Monthly, seasonal and
annual rainfall series for the period 1901-2005 have been prepared from simple
arithmetic mean of rainfall of the 19 stations, and for the period 1844-1900 the different
series have been constructed by applying the objective technique on lesser available
7
observations discussed in the previous section. Hence the rainfall sequence for the Indus
River System is developed for the period 1844-2005. The major epochs in annual rainfall
fluctuation are: 1844-1894 wet, 1895-1953 dry and 1954-2003 wet.
Yearly value of the wet season parameters for the period 1844-2005 is given in
Table 1(a) and their time series plots are shown in Figure 2(a). The mean (±1 days) of
the parameters are: starting date- 25 June (±12), ending date- 9 Sept (±13) and the
duration- 77 days (± 17). According to g-statistic test (Rao, 1967) the distribution of
starting date and duration is normal while ending date suffers from mild kurtosis. The
fluctuation of different parameters is homogeneous and random as suggested by SwedEisenhart’s run test for homogeneity and Mann-Kendall rank test for randomness against
trend.(WMO, 1966). In fact fluctuation of different parameters over all the basins under
investigation is homogeneous and random. This may be noted and will not be repeated
for individual cases any more. During a normal wet season rainfall (P) is 505.6 mm and
potential evapotranspiration (PE) 403.8 mm which shows excess rainfall of 101.8 mm
available for soil moisture utilization, ground water recharge and runoff.
In 162 years (1844-2005) period there were 62 years (given in Table 11) with two
wet seasons, one due to summer monsoon rains and another due to winter rains
associated with western disturbances. The mean (± 1 days) of the parameters of the
second wet season are: starting date- 3 Feb (± 18), ending date- 1 Mar (±25) and the
duration- 27 days (± 23).
Jhelam Minor Basin – It starts as a spring from a mountain spur at Verinag. The
river flows through the Kashmir Valley for a length of 400 km and crosses the Pirpanjal
range through a deep gorge. The tributaries are the Liddar, the Sind and the Pohru
Rivers, which rise in Kashmir and join the main river. The Jhelam River joins the
Chenab at Trimmu. The catchment area up to the Indo-Pakistan border is 34,775 sq. km.
There is no station in the catchment with long period data.
Chenab Minor Basin (drainage area: 54,501 km2; annual PE: 874.0 mm; mean
annual rainfall: 1084.4 mm- winter 15.7%, summer 19.8%, monsoon 56.3% and postmonsoon 8.2%; and annual rainy days: 57.9)- It is formed by the Chandra and the Bhaga
which rise in Lahul. It flows through Himachal Pradesh and Kashmir and after 330 km
down stream the river enters Pakistan at Akhnur. Its catchment area up to Indo-Pakistan
border is 54,501 sq.km. Rainfall data for Srinagar is available from 1891 and Jammu
and Udhampur stations were included in 1901. The rainfall series for the basin could be
developed for the period 1891-2005. The major epochs in annual rainfall fluctuation are:
1893-1941 dry, 1942-1961 wet, 1962-1974 dry and 1975-2003 wet.
Table 1(b) and their time series plots are shown in Figure 2(b). The mean (±1 days) of
the parameters are: starting date-29-May (±65), ending date- 11 Sept (±25) and the
duration- 106 days (± 70). The distribution of the wet season parameters is significantly
different from normal. During a normal wet season rainfall (P) is 593.4 mm and potential
evapotranspiration (PE) 433.5 mm which shows excess rainfall of 159.9 mm available in
the basin.
8
In 115 years (1891-2005) there were 75 years with two wet seasons and in that

Gangotri glacier (Uttar Kashi disctrict, Uttarakhand) at an elevation of 7,010 m. The
river flows through 250 km in the rugged terrain of Himalaya before descending into the
plains at Rishikesh. After traversing through Uttar Pradesh and Bihar the Ganga
bifurcates into Bhagirathi and Padma in West Bengal. The Bhagirathi is known as
Hoogly beyond Kalna and up to ‘Mouths of Ganga’ in the Bay of Bengal. The Padma
enters Bangladesh and joins Brahmaputra and later Meghna in the downstream. The river
further flows as Meghna. It breaks into number of estuaries that pass through Sunderban
to join the Bay of Bengal. The total length of the Ganga along the Hoogly is 2,525 km1,450 km in Uttar Pradesh, 445 km in Bihar and 520 km in West Bengal. The important

5.2 CORRELATION MATRIX FOR THE PARAMETERS OF THE WET
SEASON
The product-moment correlation coefficient (CC) between pair of parameters of
the wet season (starting date, ending date, duration and seasonal rainfall) for different
basins and the whole country is given in Table 12. In general, the starting date is highly
correlated with the duration which is highly correlated with ending date and the rainfall
amount. But the starting date is weakly correlated with the ending date. Early start of wet
season provides an indication that the season will be of longer duration and there will be
good rainfall activities. It may be noted that results of application of this statistical
relationship can be realized after trial of large number of years rather than on year to year
basis. Generally, the correlation between the ending date and the duration is the highest
and that between starting date and ending date lowest.
5.3
CORRELATION BETWEEN WET SEASON PARAMETERS OVER
THE WHOLE COUNTRY AND RESPECTIVE PARMETERS OF THE
INDIVIDUAL BASINS
In general seasonal rainfall over the whole country is highly correlated with the
rainfall of individual basins (Table 13). Starting date, ending date and duration of the wet
season over the country is significantly correlated with the respective parameter over
Godavari major basin (and its minor basins), Krishna major basin (and its minor basins),
Narmada, Tapi and Mahanadi major basins and Kasai, Suvarnarekha and Brahmani
minor basins. The parameters of the wet season over Ganga Major and Indus Major
Basin have shown significant correlation with the respective parameters of the whole
country but the minor basins of these major basins did not show spatially coherent
significant correlation with the whole country.
6. SUMMARY AND CONCLUSION
The present report documents the data, display and description of
statistical and fluctuation characteristics of the parameters of the wet season over
different basins of India. The chief characteristics features are:
1.
Excluding south peninsula, northeast and extreme northern India, over
remaining parts of the country starting and ending dates of the wet season are
in close agreement with onset and withdrawal dates, respectively, of the
summer monsoon (IMD, 1943).
2.
Average standard deviation of the starting date of the wet season across the
country is ±10 days that of ending date ±14 days and that of duration ±19
days.
3.
For majority of river basins probability distribution of starting date, ending
date and duration of the wet season is near-normal. However, it would be
31
interesting to know the unified probability distribution function which is the
best fit for these parameters across the country which can be taken up as
separate study.
4.
There is no significant long term trend in the parameters of the wet season for
any of the basins. But each one of them displayed domination of inter-decadal
fluctuation characterized by short term rising and declining trends.
5.
The starting date is highly correlated with the duration and the rainfall
amount for different basins and the whole country. Generally, the correlation
between the starting date and the duration is the highest. But the starting date
and the ending date is weakly correlated.
6.
On an average the wet season contributes about 78% rainfall to the annual
total. Spatially it varies from 55% in the Chenab Basin to 94% in the Tista
Basin.
7.
Over large number of basins there were two wet seasons in considerable
number of years, some times there were three wet seasons and in 1954 over
Vaigai there were four wet seasons. Details of multiple wet seasons require a
separate study.
8.
For the country as a single unit 63.8% of the wet season rainfall evaporates
and 36.2% becomes available for soil moisture storage, ground water
recharge and runoff.
Fluctuation characteristics of the wet season and rainfall over different basins
based on longest available instrumental observations documented in this report are
expected to provide vital information to water resource managers including those
working for ‘interlinking of rivers’ program of the country. Further research in this area
could be to refine this start and cessation dates of the wet season using shorter period
rainfall data such as daily, pentad or weekly. Of course the shorter period rainfall data is
available only from 1901 onwards.
