Coupled chemistry climate model simulations of stratospheric temperatures and their trends for the recent past

摘要: Temperature results from multi-decadal simulations of coupled chemistry climate models for the recent past are analyzed using multi-linear regression including a trend, solar cycle, lower stratospheric tropical wind, and volcanic aerosol terms. The climatology years is in good agreement with observations troposphere but model diverge each other stratosphere. Overall, agree better than previous assessments, primarily because corrections observed temperatures. annually averaged global polar temperature trends simulated by generally revised satellite radiosonde data over much their altitude range. In average, underpredict slightly at top Over Antarctic some trend stratosphere, while others overpredict trends.
