1 Indian Atlas of Rainfall Spatial and Temporal Variations INSTRUMENTAL PERIOD RAINFALL VARIATION OVER HOMOGENEOUS ZONES, STATES AND METEOROLOGICAL SUBDIVISIONS OF INDIA (1813-2003) Nityanand Singh N.A. Sontakke H.N. Singh Indian Institute of Tropical Meteorology, Pune 2005 Part II

2 Scale 1:11M ADMINISTRATIVE UNITS Figure 1 26

3 Development of Longest Rainfall Series 1871-2003: Area-averaged values using all available data Prior to 1871: Constructed values using established objective method on limited observations. (Reliability of each constructed rainfall mount is indicated by giving correlation coefficient between representative rainfall series (1871-2000) and the corresponding rainfall series of mean rainfall series of the lesser available gauges).

4 CONTENTS 1. Longest instrumental monthly, seasonal (win, sum, monsoon, post-monsoon, Jun-Jul_Aug, Jul-Aug, Oct-Nov and May-Nov) and monsoon monthly rainfall data of seven homogeneous zones, 21 states and different meteorological subdivisions for the period during 1813-2003 (depending upon available data from the region/sub-region) in tabular form. 2.Time series plots of annual, seasonal (win, sum, monoon and post-mon) and monsoon monthly rainfall. 3.Normal annual potential evapotranspiration (PE), start, duration and end of rainy season, number of rainy days (days with rainfall greater than 2.5 mm), wet/dry epochs in the annual rainfall temporal pattern etc. Hard bound Atlas is of 173 pages on Super A3 size Paper (329mm by 483mm)
