The impact of climate change is projected to have its effects both on global and regional basis. The most adversely affected weather parameters due to the changing climate are global temperature and rainfall pattern. The temperature shows an increasing trend whereas the rainfall shows an anomalous trend all over the world. The change in rainfall trend has direct and adverse effects on land and water resources, agricultural practices and thus on total ecosystem. India is also facing the problems developed due to climate change. In the present study, the anomalous behaviour of rainfall due to climate change in the context of Indian subcontinent has been established using 1° x 1° gridded daily rainfall data of India Meteorological Department (IMD) from January 1951 to December 2004. Both, temporal and spatial variation of rainfall have been analysed utilizing statistical tests and presented using ArcGIS 9.1.
