摘要
利用地表热源的气候学计算方程,建立了中国47个站地表热源的时间序列,分析了中国地表热源的多年变化规律。进而又分析了中国地表热源与南方涛动指数间的交叉谱,指出中国地表热源与南方涛动指数之间各地都在9年、3年的准周期上有显著相关。这表明中国各地地表热源与南方涛动指数的联系,可能存在着某种共同的物理过程。
The time series of 47 stations for the earth surface heat source in China are eslablished using the climatological equation of the earth surface heat source. the change regularity this of the earth surface heat source for many years is found, In this paper,the cross spectrum between the earth surface heat souce in China and the South Oscillation Index is given. The results show that there are colse relationships in terms of quasiq years and quasi 3 years periods between the earth surface heat source in China and the south Oscillation Index. It is suggested that there may be some common physical processes for the relation between earth surface heat source over china and the South Oscillation Index.
