The Biafo Glacier, located at about 35.8°N and 75.7°E, is one of the largest glaciers in the Karakorum region, and 59 km long and 3.4× 10<SUP>2</SUP> km<SUP>2</SUP> in area. The snowline lies at about 4600 m above sea level. For about one month in the summer of 1977, glacial-meteorological observations were carried out on the ablation area (4100 m a.s.1.) and accumulation area (4900 m a.s.1.). The results on the ablation area showed that the air temperature on moraine-covered ice was about 7°C higher than that on the bare ice. A glacier wind originating from the upper part of the glacier blows down the glacier without changing wind direction the whole day. The weather on the glacier varied with a period of about 10 days, which corresponds to the fluctuations of the westerly wave. The summer weather in the Karakorum is considered to be influenced largely by westerly wave rather than the monsoon which is pronounced in the Nepal Himalaya.
