摘　　要：利用1999年1月—2009年12月的ISCCP卫星云量资料,分析了总云量及高、中、低云量在东海海域的时空分布特征。结果表明,东海海域各季节低云量高值区边缘沿海岸线分布,总云量、中云量和高云量存在显著的时空分布差异;春季、秋季和冬季低云量和中云量在总云量中占主体,夏季尤其是6月份,高云量是总云量的重要组成部分;总云量和高、中、低云量的日变化形式相对稳定且变化趋势各不相同。The temporal-spatial distribution characteristics of the total, high, medium and low cloud cover over the East China Sea are analyzed based on the ISCCP monthly mean D2 data from January 1999 to December2009. The results show that the high value area margin of low cloud cover distributes along the coast throughout all seasons and significant temporal-spatial distribution difference exists among the total, medium and high cloud cover. It is noted that in summer, especially in June, the high cloud cover constitutes an important part in the total, while the low and medium cloud cover plays a leading role in spring, autumn and winter. Further analysis indicates that the diurnal variation form of each cloud cover is relatively stable, although their changing trends are disparate.
