This document contains the presentation by A.P.Dimri on "Wintertime Climatic Analysis over the Western Himalayas", presented at National Climate Research Conference, IIT Delhi, March 5-6, 2010. The eastward moving synoptic weather systems, Western Disturbances (WDs), are the most dominant source of precipitation over the western Himalayas. Topographic variability and landuse heterogeneity influences these circulation features in the lower and upper troposphere. This interaction determines the accumulation of wintertime precipitation, in the form of snow, over the western Himalayas. Also, this winter precipitation is the main source for north Indian rivers. In the context of today
