Abstract: In the southern great plains, winter weather can have large impacts due to heavy icing and inadequate mitigation resources. The boundary between cold arctic air from the north and warm gulf moisture to the south is a consistent forecasting challenge for models even in the short-term.
Tropopause-penetrating convection is capable of rapidly transporting air from the lower troposphere to the upper troposphere and lower stratosphere (UTLS). Since the vertical redistribution of gases in the atmosphere by convection can have important impacts on the chemistry of the UTLS, the radiative budget, and climate, it has become a recent focus of observational and modeling studies.
