Abstract
The Himalaya, the longest chain of mountains in the world, shows complex va riations in snow and meteorological conditions as one traverses from east t o west and from south to north. The paper presents the analysis of the past 25 years of snow precipitation and avalanche occurrence data of the Wester n Himalaya region and delineates the region into three principle zones: Low er, Middle, and Upper. While the Upper Himalaya Zone is close to polar regi on characteristics, the Lower and Middle Himalaya compares well with the Ma ritime and Continental Zones. Avalanche forecasting in the Himalayan region is biased towards a conventional knowledge-based approach. The variation i n three zones on avalanche activity in the region has been discussed. Diffe rent approaches of avalanche forecasting developed so far, however, require experienced observers and forecasters, which causes problems because of th e temporary nature of avalanche jobs. It has been seen that each zone warra nts separate treatment and models for prediction of avalanches at any one t ime. (C) 2000 Elsevier Science B.V. All rights reserved.
