Abstract

  Rainfall is important parameters of weather and climatology. Being located in close vicinity of Bay of Bengal, West Bengal experiences large vagaries in the monsoon and annual rainfall. In view of this, in the present study different aspects of monsoon and an- nual rainfall variation for the two meteorological sub-divisions are studied with reference to Standardized rainfall anomaly index, Precipitation concentration index, and coefficient of variation using monthly rainfall data (1901 - 2016) of West Bengal. The analysis revealed that the spatial and temporal analysis are influenced by climate change especially 1990 onward showing increase in percentage of dry years in Gangetic West Bengal (75% to 97%) although increase in rainfall is seen during 2001 - 2016. Even southern districts of Sub-Himalayan West Bengal showed increase in dry year’s percentage (69% to 84%). This is serious condition from agricultural as well as water resources planning point of view.
