纳木错湖地区近地层微气象特征及地表通量交换分析

Characteristics of Micrometeorology and Exchange of Surface Energy in the Namco Region

利用中国科学院青藏高原研究所纳木错圈层相互作用综合观测研究站2006年全年的观测资料,研究了青藏高原纳木错地区的草甸下垫面气温、湿度、风速、风向和地表温度的日变化及季节变化规律,并研究了地表感热、潜热通量和辐射通量的日变化和季节变化规律,初步揭示了纳木错地区草甸下垫面微气象特征和地气能量交换的一般规律。

Using the data collected at Namco station in 2006, the characteristics of micrometeorology and exchange of surface energy are analyzed in the Namco region. The results shows： （1） Daily range of air temperature is high, month change is obvious, monthly average minimum value is --11＂C in February and monthly average maximum value is 13＂C, the relative humidity is high from May to September than it during February and March; （2） The sensible heat flux is higher than the latent heat flux during dry season, but the latent heat flux is dominant during wet season; （3） During monsoon period the net radiation is the largest in the Namco region.
