Brief Description (Abstract):

Network of rain-gauge stations: While selecting the network of rain-gauge stations, an effort was made to select a network which would provide one representative station per district having a reliable record for the longest possible period. The network selected under these constraints consist of 306 almost uniformly distributed stations for which rainfall data are available from 1871. The hilly regions consisting of four meteorological subdivisions of India which are parallel to Himalayan mountain range have not been considered in view of the meagre rain-gauge network and low areal representation of a rain-gauge in a hilly area. Two island subdivisions far away from mainland have also not been included. Thus, the contiguous area having network of 306 stations over 30 meteorological subdivisions measures about 2,880,000 sq.km., which is about 90 percent of the total area of the country. Preparation of Subdivisional/Regional rainfall series The monthly (January - December) area weighted rainfall series for each of the 30 meteorological subdivisions have been prepared by assigning the district area as the weight for each rain-gauge station in that subdivision. Similarly assigning the subdivision area as the weight to each of the subdivisions in the region, area weighted monthly rainfall series are prepared for Homogeneous regions of India as well as for all India.
