Variability of upper tropospheric clouds in the polar region during stratospheric sudden warmings

The variability of upper tropospheric clouds during stratospheric sudden warmings (SSWs) in 2009, 2010, and 2012 in the Northern Hemisphere is examined using satellite observations and reanalysis data. It is shown that the zonal mean cloud frequency …

Simultaneous occurrence of polar stratospheric clouds and upper-tropospheric clouds caused by blocking anticyclones in the Southern Hemisphere

Previous studies have reported that polar stratospheric clouds (PSCs) are frequently observed simultaneously with upper-tropospheric clouds (UCs) in the Southern Hemisphere. However, it has not yet been examined whether the UCs that simultaneously …

The effects of atmospheric waves on the amounts of polar stratospheric clouds

A quantitative analysis on the relationship between atmospheric waves and polar stratospheric clouds (PSCs) in the 2008 austral winter and the 2007/2008 boreal winter is made using CALIPSO, COSMIC and Aura MLS observation data and reanalysis data. A …
