【 摘 要 】

Forecasting minimum surface temperature ata station, Stage II, located in mountainous region requires informationon the meteorological fields. An attempt has been made to develop astatistical model for forecasting minimum temperature at ground levelusing previous years' data. Surface data were collected at StageII(longitude 73 oB, latitude 34 oN, and altitude 2650 m). Atmosphericvariables are influenced by complex orography and surface features to agreat extent. In the present study, statistical relationship betweenatmosphere parameters and minimum temperature at the site has beenestablished. Multivariate linear regression analysis has been used toestablish the relationship to predict the minimum surface temperaturefor the following day. A comparison between the observed and thecalculated forecast minimum temperature has been made. Most of the casesare well predicted (multiple correlation coefficient of 0.94).
