摘要：

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