Abstract利用980年Nibus-7卫星网络点资料(温度场)对中层大气行星波的空间结构进行诊断和分析后发现,行星波扰动主要集中于冬半球,夏半球及赤道地区上空的扰动则相我弱,但也不可忽视,冬半行星波扰动中的瞬变波部分可以跨过赤道向夏半球传播,且传播主要集中于20km和70km两个高度层附近,波数1冬季以准定常行星星波为主,夏季瞬变行星波与准定常行星波波幅相当,行星扰动的波幅从冬到衰减主要表现在波数1和波数2
Other AbstractPlanetary waves and its propagation are very important in the middle atmosphere.Meteorologists have done a lot of researches on how the planetary waves vary in time-scales.Using the Nimbus 7 satellite grid data,this paper is concentrated on diagnosis and analysis of the spatial structure of the planetary waves in the middle atmos-phere in 1980.The results show that perturbations are mainly in the winter hemisphere and relatively weak in the summer hemisphere as well as equatorial areas, but can not beignored.The transient waves which propagate to the summer hemisphere across equator is mainly through two height channels-20km and 70km. The standing waves stay in winter hemisphere.The attenuation of the amplitude from winter to summer can be found in wave 1 and wave 2.The energy in wave 3 nearly remains constant.
