基于MODIS云产品的北京地区卷云特性统计分析

利用2007年1月到2008年12月北京地区MODIS云产品数据(MYD06),对北京地区卷云的光学厚度、有效尺度、和卷云云顶高度的概率分布和季节变化进行了统计分析,并对卷云出现的概率分布进行了研究。结果表明,卷云的云顶高度主要分布在6～12 km处,典型高度在9 km左右,卷云云顶高度分布随季节变化而变化。卷云的有效尺度主要分布在20～80 μm之间, 40～50 μm间概率最大。卷云有效尺度随季节变化不大,并在一定程度上依赖于卷云的云顶高度。北京上空出现的冰云基本上都是不透明冰云。卷云光学厚度主要分布在0～10间,光学厚度小于5出现的概率大。冬季北京地区卷云出现的概率较小,光学厚度较小。

Abstract

Based on the MODIS cloud products data (MYD06) in Beijing region from January 2007 to December 2008, the probability distribution and seasonal variation characteristics of cirrus optical thickness, effective size and cirrus top height were analyzed. Cirrus probability of occurrence was also studied. The results show that the distribution of cirrus top height is mostly from 6 km to 12 km, the typical cirrus top height is about 9 km. The distribution of cirrus top height varies with seasons. The distribution of cirrus effective size is from 20 μm to 80 μm mostly, and the most probable cirrus effective size is from 40 μm to 50 μm. The relation between cirrus effective size and seasons is not very obvious, but cirrus effective size is definitely dependent on cirrus top height. The ice clouds in Beijing region are mostly opaque. The distribution of cirrus optical thickness is mostly from 0 to 10, and the probability of cirrus optical thickness is bigger when cirrus optical thickness is less than 5. The probability of occurrence and optical thickness of cirrus in winter is small.
