Abstract
Meteorological observations were carried out in the debris-free and debris-covered areas of Khumbu Glacier, Nepal Himalayas from May 22 to June 1, 1999. Comparisons of meteorological features in the both areas were made. There was little difference of the net radiation between the both areas. The distinct valley wind could be recognized. The air temperature in the debris-covered area was higher than that in the debris-free area. The difference became small in the daytime because the valley wind increased in the daytime and could diffuse the heat.
