为了分析中国陆地区域深对流激发平流层重力波的特征，针对2010年7月20日发生在吉林上空的一次暴雨事件，利用Aqua卫星高光谱大气红外探测器（Atmospheric Infrared Sounder, AIRS）的观测数据并结合ERA-interim高空背景场数据和S变换小波分析方法，分析了与暴雨相伴的深对流激发平流层重力波的传播特征，进一步讨论了重力波上传过程对暴雨发展的可能影响。

To analyze the characteristics of the gravity waves excited by the deep convention stratosphere in the land area of China, the propagation characteristics of the gravitational waves excited by deep convention stratosphere accompanied with heavy rainstorm are analyzed. This analysis is carried out for a rainstorm event occurred over Jilin province on July 20, 2010. In the analysis, the observation data from the Atmospheric Infrared Sounder (AIRS) onboard the Aqua satellite are used with the ERA-interim field data and the S-transform wavelet analysis method. The possible influence of gravity wave propagation on rainstorm development is further discussed.
