Satellite-derived vertical dependence of tropical tropospheric temperature trends
[1] Tropical atmospheric temperatures in different tropospheric layers are retrieved using satellite-borne Microwave Sounding Unit (MSU) observations. We find that tropospheric temperature trends in the tropics are greater than the surface warming and increase with height. Our analysis indicates that the near-zero trend from Spencer and Christy’s MSU channel-2 angular scanning retrieval for the...
متن کاملVertical Profiles of Temperature Trends
WHAT: Forty-five scientists from four continents discussed changes in vertical temperature structure and what might be causing these changes. WHEN: 13–17 September 2004 WHERE: Hadley Centre, Met Office, Exeter, United Kingdom his workshop aimed to further our understanding of observed changes in upper-air temperatures and their relationship to observed surface and boundary layer climate evoluti...
متن کاملMean Annual Temperature Trends and Their Vertical Structure in the Tropical Andes
Mean annual temperature trends in the tropical Andes were determined over the last six decades (19391998), to investigate the apparent inconsistency between the observed glacier retreat and the reported slight cooling trend in the lower tropical troposphere after 1979. Our results indicate that temperature in the tropical Andes has increased by 0.10 ø 0.11 øC/decade since 1939. The rate of warm...
متن کاملTropical sea surface temperature, vertical wind shear, and hurricane development
[1] The anomalously strong hurricane activity in the Atlantic sector during the recent years led to a controversy about the impact of global warming on hurricane activity in the Atlantic sector. Here we show that the temperature difference between the tropical North Atlantic and the tropical Indian and Pacific Oceans (IndoPacific) is a key parameter in controlling the vertical wind shear over t...
متن کاملOn the seasonal dependence of tropical lower-stratospheric temperature trends
This study examines the seasonality of tropical lower-stratospheric temperature trends using the Microwave Sounding Unit lower-stratospheric channel (T4) for 1980– 2008. We present evidence that this seasonality is largely a response to changes in the Brewer-Dobson circulation (BDC) driven by extratropical wave forcing. We show how the tropical T4 trend can be used as an indicator of changes in...
