Abstract

Meteorological observations and characteristics of annual and daily meteorological variables measured by the GEN-AWS in the Nepal Himalayas from October 1994 to October 2000 are presented in this report. The history of maintenance of the observation system from May 1996 to October 2000 is also summarized. The observations show unique seasonal changes in the mountain weather in the Khumbu Himalayas with large year-to-year changes in winter air temperature and snow cover conditions, and heavy precipitation events, even though data have been accumulated for about 5 years.
