Seasonal dependence of stratospheric temperature variations

On 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...

Global distribution of total ozone and lower stratospheric temperature variations

This study gives an overview of interannual variations of total ozone and 50 hPa temperature. It is based on newer and longer records from the 1979 to 2001 Total Ozone Monitoring Spectrometer (TOMS) and Solar Backscatter Ultraviolet (SBUV) instruments, and on US National Center for Environmental Prediction (NCEP) reanalyses. Multiple linear least squares regression is used to attribute variatio...

Seasonal variations of the atmospheric temperature structure at South Pole

[1] Fe/Rayleigh lidar measurements are combined with the high-altitude balloonsonde data and used to characterize the seasonal variations of atmospheric temperature at South Pole from the surface (2.835 km) to 110 km altitude. Twelve-month oscillations, associated with solar UV absorption by ozone, dominate the seasonal variations of temperature throughout the stratosphere and lower mesosphere ...

Dynamical implications of seasonal and spatial variations in Titan's stratospheric composition.

Titan's diverse inventory of photochemically produced gases can be used as tracers to probe atmospheric circulation. Since the arrival of the Cassini-Huygens mission in July 2004 it has been possible to map the seasonal and spatial variations of these compounds in great detail. Here, we use 3.5 years of data measured by the Cassini Composite InfraRed Spectrometer instrument to determine spatial...
