Abstract

North-west Himalayan region comprises five mountain ranges. Their orientation and complexterrain influence the weather over the region. Sudden altitudinal changes also affect the weathersystems to a considerable extent . Due to the prevailing in homogeneous topography, various dynamicand thermal processes take place at mesoscale level. In synoptic scale, during winter seasons, weathersystems, named, western disturbance (WD), take their southerly track and travel over J&K, HP andhills of western UP, and yield considerable amount of precipitation. On the basis of past historicaldata collected over J&K region, the pattern of snowfall and its frequency distribution was studiedusing statistical means. Variation of these snowfall spells was also studied to understand spatial andtemporal changes in their distribution. A brief case study of a WD has been carried out to estimatemoisture flux inflow over Himalayas.
