| Abstract: | Using the ECMWF Interim Re-Analysis(ERA-Interim)data from 1989 to 2008 and the simulations from 1980 to 2019,which are produced by a chemistry-climate model,variation characteristics and trends of the tropical tropopause layer(TTL)structure are analyzed.It is found that the TTL characteristics have significant seasonal and spatial variations.The thickness of the TTL in summer and autumn is the thinnest in the Northern Hemisphere and it has the largest seasonal variability in winter in the Northern Hemispher... |
