摘要
通过对北半球高纬近地面大气经向运动变化、北半球 1 0 0 h Pa极地低压环流变化、赤道附近 2 0 0 h Pa和 85 0 h Pa大气纬向运动变化等现象的分析 ,指出北半球1 0 0 h Pa极地低压环流变化是与日、月引潮力场周期变化高相关的大气振荡现象 ,另二者的变化与月球引潮力场变化周期同步或基本同步。
By analyzing the meridional variation of atmospheric motion over polar high latitude of the Northern Hemisphere,the circulation variation of the Northern Hemisphere polar low at the 100hPa level,the longitudinal motion variation of polar low at the 200hPa and the 850hPa level near the equator and so on,the synchronization or the high correlation between the variation period of atmospheric motion and that of lunar tide generating force field was revealed.That those known statistical phenomena,such as the quasi synchronous variation of global subtropical high,the 6-7 day periodic oscillation of subtropical high over the Weat Pacific,the about 14 day oscillation of general circulation of atmosphere,the about 7 day and about 14 day weather natural period and so on,are the results of lunar tide generating force field affecting global atmosphere.
