摘要
利用2005年8月31日～9月5日中国科学院珠穆朗玛峰综合观测研究站的LAP3000风廓线仪的观测资料，分析了该地区气温日变化和大气边界层风廓线结构。结果表明，该地区1500m以下大气边界层主要受高原山地地形及珠峰地区冰川环境的影响，冰川风可能是引起观测期间下午强风天气的主要原因；1500m以上高空受西风气流影响程度增大，但东南风仍占有一定比例。
Using the data of the LAP3000 Wind Profiler set on the Comprehensive Observation and Research Station on Qomolangma, CAS （CORSQ） from August 31 to September 5, 2005, the diurnal change of air temperature and the atmospheric boundary layer wind profiles are analyzed. The result shows that the mountainous landform and the glacier environment of Mt. Qomolangma region had a major influence on the lower atmospheric boundary layer, and the strong wind that took place in late afternoon which was probably caused by the glacier wind from Mt Qomolangma. In the upper air above 1500 m, west airflow became the major, but the southeast wind sill existed at a ratio of about 15% during observation.
