| 摘 要： | 本文设计了一种恢复夏季大气环流场的EOF(经验正交函数)迭代方案,并利用1951～1984年中国夏季降水距平场和北半球500hPa夏季高度距平场作镢复试验,数值试验效果较好.此项工作表明:利用某些长时间序列的资料通过EOF迭代方案恢复历史时期大气环流是可行的.

| Abstract: | In this paper, a new method of reconstructing the summer atmospheric circulation is given based on the empirical orthogonal function (EOF) iteration scheme. By the method some experiments are done by authers using summer 500 hPa height anormalies in the Northern Hemisphere and summer rainfall departures for 160 stations in China during the 1954-1984 period. The experimental results show that the new method can be used to reconstructe the general circulation in palaeoclimate. |
