近二十年全球变暖背景下东亚地区云量变化特征分析
TREND OF CLOUD AMOUNT IN EAST ASIA UNDER THE BACKDROP OF GLOBAL WARMING IN THE PAST 20 YEARS
摘要
Abstract
Based on ISCCP D2 data sets over the period of 1984-2006, the change trends of total cloud amount, high cloud amount, middle cloud amount and low cloud amount over Asia are analyzed. Then, in the backdrop of global wanning, the correlation between air temperature and change of the cloud amount is mainly discussed. The study has the following results. (1) In East Asia, the total cloud amount, high cloud amount and low cloud amount have a spirally decreasing trend in the past 23 years, with the reduction rate being -2.24%, -1.65% and -1.68% respectively, but the middle cloud amount has been increasing by a rate of 1.07%. (2) It is found from the spatial distribution that the change trends of the cloud amount (of total, high, middle and low levels) are distinctly different in East Asia. (3) The air temperature and water vapor variation are distinctly responsible for the change in the spatial distribution of cloud amount. (4) The correlation is negative between air temperature and high cloud amount but positive between air temperature and low cloud and middle cloud amounts in the Bay of Bengal, Qinghai-Tibet Plateau and subtropical western Pacific.关键词
