Impact of deep convection to water vapor vertical transport in the lower stratosphere at high latitudes

Abstract:

Observations from the precipitation radar onboard the Global Precipitation Mission satellite during the first year have showed that there are numerous deep convection reaching above the tropopause at mid and high latitudes over northern hemisphere land. These deep convection could transport water vapor into the lower stratosphere. However, it is important to understand the impact of the water vapor transport into the stratosphere. This study examines the AURA MLS water vapor observations at the lower stratosphere and upper troposphere at mid and high latitudes in both northern and southern hemisphere. The results are compared to the seasonal variations of the deep convection over the same region.
