| 摘 要： | 利用玛曲地气相互作用试验2005年11月25日至2006年1月15日梯度站的观测资料,分析研究了青藏高原东部玛曲地区冬季小气候特征和地表辐射特征。结果表明,冬季玛曲地区存在较明显的局地环流,夜间有辐射逆温和逆湿现象存在。辐射各分量均小于青藏高原北部的观测值,晴天条件下太阳短波向下辐射和地面短波向上辐射均有明显的日变化规律。

| Abstract: | Using the land-atmosphere interaction experiment data observed at Maqu station,the microclimate and surface radiation characteristics over Eastern QinghaiTibet Plateau in winter were analyzed.The results show that there are obvious local circulation in Eastern Qinghai-Tibet Plateau in winter and radiation inversion and inverse humidity phenomenon at the night.Radiation budget components of the Eastern Qinghai-Tibet Plateau in winter are less than that of the Western Qinghai-Tibet Plateau in winter.There are obvious daily variation of downward shortwave radiation and upward shortwave radiation at clear day. |
