| 摘 要： | 利用ISCCP提供的1983年7月－1993年12月3h一次的月平均卫星决云量资料，将整个高原分为39个网格点，分析了高原总云量的年、季节、日变化规律及其空间分布特征，并根据高原水汽条件和地形动力影响以及环流特征作出一定的科学解释。将ISCCP总云量与地面观测总云量分布形势作了比较，证明了ISCCP－D2资料的合理性。对总云量与OLR进行相关分析，发现夏季相关好，冬季相关差。

| Abstract: | The spatial characteristics and yearly,seasonally and daily variation properties of total cloud cover is analyzed in this paper based on every-three-hour mean monthly data of ISCCP from July,1983 to December,1993 over the Tibetan Plateau which is divided into 39 grids.Some scientific explanation are also made for the moisture condition,topographic dynamics and circulation patterns over the Plateau.Comparing the distribution of total cloud cover from ISCCP with that observed from surface stations,the rationality of ISCCP-D2 data is validated.It is concluded that there is a good (poor) correlation in summer (winter) by analyzing the correlation between the total cloud cover and OLR. |
