Abstract: The role of vertical mixing processes in destroying tropopause folds is studied with the help of a two-dimensional isentropic model. Two vertical diffusion parameterizations are tested. The first parameterization was ...

Abstract: A two-layer isentropic model is used to examine the parameters controlling the severity of cold-air outbreaks east of the Rocky Mountains, and in particular the channeling effect of the mountain range. The case that is ...
