利用1998年5月-7月在改则、当雄和昌都三测站获得的近地面层气象要素变化的观测资料,分析了青藏高原近地面层风速、温度和湿度日变化特征及廓线规律,发现高原近地面层微气象学特征具有其自己的特点;同时还讨论了高原近地面层白天出现的逆湿现象.rn“,”The data of the meteorological elements in the surface layer have been analyzed which were obtained during the IOP of TIPEX fiom May to July 1998 in Gerze, Damxung and Qamdo. The characteristics of the diurnal variations and the vertical profiles of the wind velocity, temperature and humidity in the surface layer have been investigated. Some interesting results have been obtained. The moisture inversion phenomena occured during the daytime in the surface layer have also been discussed.
