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-nterim field data and the S-transform wavelet analysis method. The possible influence of gravity wave propagation on rainstorm development is further discussed.
