摘要
Abstract
The authors use the detrended fluctuations analysis （DFA） to analyze the ISCCP cloud amount data at four locations： Beijing, Shanghai, Western Pacific, and Eastern Pacific. It is found that cloud amount indeed has power-law correlation in large time scales, which indicates that the cloud amount has strong long-term correlation in the locations studied. The crossover over the ocean appears later than that over the continent.The long-term correlation of the the cloud amount over the Western Pacific is stronger than the Eastern Pacific＇s.关键词
