Abstract:

 Based on sounding data of 120 meteorological observation stations in China from 1980 to 2007，the height of tropopause，
tropospheric temperature and temperature at low stratosphere were calculated． Temperature changes caused by greenhouse effects in
China were analyzed，and mainly the correlations between the tropospheric temperature，the temperature of lower stratosphere and the
tropopause height variation were analyzed． The main results revealed that the tropospheric temperature had an increase of nearly 3． 9 ℃
from 1980 to 2007 in China caused by global warming，the warming was more obvious in winter than that in summer． The lower stratospheric
temperature decreased by 7． 0 ℃ from 1980 to 2007． The tropopause height increased by 45 meters in 28 years，the tropopause
height change was in the range of 8 － 16 km． From annual change of the tropopause height，it was negatively related to lower stratospheric
temperature and positively associated with the troposphere temperature，and there was seasonal difference． The joint effects of
warming in the troposphere and cooling in the stratosphere resulted in tropopause height variation in China．

Key words:  greenhouse effect, tropopause height ,  tropospheric temperature, lower stratospheric temperature

摘要：

对我国1980 ～ 2007 年120 个观测站的探空资料进行处理后，分别计算得出对流层顶高度、对流层温度和平流层低层温度。在对温室效应引起我国气温变化进行研究的同时，重点分析对流层温度和平流层低层温度与对流层顶高度变化之间的关系。结果表明: 全球性温室气体的排放导致我国对流层温度1980 ～ 2007 年增加了近3． 9 ℃，其中夏季增温较冬季明显，而平流层低层温度则呈降低趋势，降幅约7． 0 ℃; 28 a 来我国对流层顶高度总体上升约45 m，高度变化范围在8 ～ 16 km 左右; 从平均对流层顶高度的年变化看来，对流层顶高度与平流层低层温度呈负相关，与对流层温度呈正相关，且存在季节差异。对流层的增暖和平流层的冷却作用共同导致了我国对流层顶高度的变化。
