摘要

摘要: 分析了南半球对流层500hPa平均地转西风随纬度的分布特点,平均地转西风季节变化特点,计算分析了南半球位势高度对纬向平均的偏差,分析了超长波的分布特征。以上结果均与北半球同期计算结果作了对比比较,指出了南北半球大气环流的异同点。

Abstract: Based on the global geopotential height 5°×5°grid data from European Center for Medium-range Weather Forecast (ECMWF) and Washington KEBC, the meridional distribution of mean geostrophic westerly in lower stratosphere (500hPa) of Southern Hemisphere was analyzed. Also the seasonal variation of mean gedstrophic westerly, and the distribution of extra-long wave at this layer were analyzed. All results above were compared with those of Northern Hemisphere, and the same features or differences of the atmospheric circulation in Northern and Southern Hemisphere were pointed out, respectively.
