摘要
利用NCEP-NCAR月平均的高空风场资料,对东亚对流层上层大气环流变化的年进程进行了分析研究,发现北半球西风急流、热带东风气流、越赤道气流、南亚高压和太平洋中部存在明显的季节变化,而且它们之间这种年进程相互关联。
used the NCEP - NCAR long .time monthly mean winds data, analysing the main circulation pattern in the upper troposphere in Asia, characteristic are found among the subtropical we sterly jet, tropical easterly jet and the upper troposphere anticyclone. The interrelated characteristic of these main atmospheric circulation systems are very important for us to realize the climate background.
