摘要
利用“中国科学探险协会2002年北极科学探险考察”期间在北极朗伊尔宾地区获得的大气风温微气象脉动资料,讨论了该地区近地层湍流能谱、湍流方差、感热通量、动量通量、温度结构参数以及动量整体输送系数等的分布规律,给出了这一极端环境区夏季近地层微气象场的基本结构,分析了北极地区极昼期间陆地下垫面地-气之间能量交换,丰富了人们对该地区近地层湍流输送过程的深入理解。
The turbulence fields such as turbulence spectrum, eddy heat flux,temperature structure coefficient and bulk transport coefficient are studied in Lonyearbyen, the capital of Svalbard with the micrometeorology data observed by China Association for Scientific Expedition in 2002. It presents the basic structure of the micrometeorology fields in the extremely condition area in summer. The exchange of energy between land and atmosphere is also analyzed during polar days in the Arctic area. The results show the eddy transport process of surface layer in Arctic land area.
