A Diagnostic Equation for Tendency of Lapse-Rate-Tropopause Heights and Its Application

The tropopause is the boundary between the troposphere and stratosphere and is normally defined by the temperature lapse rate. Previous studies have noted that synoptic-scale and planetary-scale disturbances bring about lapse-rate-tropopause (LRT) …

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 …
