摘要
利用2007年1月—2013年12月的COSMIC掩星观测的温度廓线资料,分析了东亚地区对流层顶逆温层各要素的时空分布特征.结果表明,在东亚对流层顶逆温层(TIL)是普遍存在的现象,TIL有着一致的纬向结构,热带和温带间TIL有着显著差异,TIL各要素在40°N以南和以北表现出相反的季节变化特征;在热带海洋地区TIL薄而强,中高纬TIL结构表现出"对流层顶断裂"特征,在该区域内TIL更深而强度较弱.
By using temperature profile of COSMIC occultation data during January 2007--December 2013,the spatial and temporal distributions of variety elements of TIL （ the Tropopause Inversion Layer） in East Asiahave been analyzed.The results show that it is a common phenomenon in East Asia that the TIL exists.The zonalstructure of TIL is obvious, and the TIL between the tropical and the extra-tropical is different, while the seasonalvariation of TIL is opposite in the south and north of 40°N.The strong tropopause inversion layer appears over thetropical sea,where the TIL is thin, and the TIL is thick and weak in ＂the tropopause breaking belt＂ in the mid-and high-latitude.
