摘要
本文利用美国GFDL的10年(1963年5月—1973年4月)气候平均格点(5.0°×2.5°)资料,计算了全球7层等压面上温度、高度(气压)纬度距平,并以此为基础讨论了海陆分布对平均大气环流的影响。分析发现海陆影响中大陆起主要作用;北半球是全球海陆影响变化最大的半球,欧亚大陆是北半球的变化中心;海陆分布对平均大气环流的影响冬季最强,夏季最弱。
In this paper, temperature and geopotential height(pressure) departures along latitude are calculated by using ten-year mean(1963, 5-1973, 4) climatic data of CFDL in USA and influence of land-sea distribution on general circulation of atmosphere is discussed. It is shown that land plays the main role, the biggest variation of influence of land-sea distribution on general circulation of atmosphere appears in the north hemisphere. The center of variation in the north hemisphere is over the Eurasian continent. The stronggest influence of land-sea distribution on general circulation of atmosphere appears in winter, and the smallest in summer.
