摘　　要： 对热带17层气温纬向偏差垂直剖面和气温异常垂直剖面进行了分析,发现热带太平洋大尺度准定常热源温度波和下垫面温度异常温度波都能激发温度偶极振子,使温度波波及对流层和平流层高空,不仅改变了高空大气的热力状态,也使大气热力状态随高度的分布呈现出明显的波状结构。 In this paper, the vertical profiles of the zonal air temperature diviation and the abnormal air temperature in the tropics are analysed, and it is shown from the analysis results that both the temperature wave of large scale quasi-steady heat source and the temperature wave of underlying surface temperature (anomaly) in the tropical Pacific can arouse the temperature dipole oscillators and the temperature waves can be transmitted to the troposphere and stratosphere, which will not only change the thermodynamic state in the upper atmosphere but also make the distribution of atmospheric thermodynamic state with altitude show obvious wavy structures.
