Purpose

The project name is ""Understanding the role of deep convection in determining the humidity structure in the upper-troposphere and lower-stratosphere (UTLS) and improving model simulation of the process using satellite observations"". Atmospheric water vapor plays a significant role in climate change, but its variation in the UTLS region is currently poorly understood and inadequately simulated by global weather and climate models. Satellite data will be used to quantify the impact of air mass circulation on UTLS water vapor. Operational global models of ECCC will be validated against the observations and high resolution cloud resolving simulations. This research will help improve Canada's ability to predict climate and weather and shed light on future climate monitoring missions.
