• Weather radars provide surface rainfall intensity estimates based on Marshal Palmer relation, these estimates have high spatial and temporal resolution in comparison to surface observation network. Hence, an attempt to derive climatology of rainfall based on weather radar past 8-10 yrs data is being made. This work serves two purposes: first namely derivation of climatology of rainfall based on Doppler weather radar 8-10 yrs data. Second is to prepare climatology for extreme weather events associated with Western Disturbance such as hailstorm, thunderstorm which impacts northern India during winter months mainly.
