Abstract: Numerical simulations using the Penn State University/NCAR MM4 model are performed to examine a dry, stably stratified, zonal easterly flow past a large-scale three-dimensional mountain range in a rotating, initially ...

Abstract: A mechanism that acts to produce vorticity in the lee of large-scale mountain ranges embedded in an easterly flow in a stably stratified rotating atmosphere is investigated as it applies to the production of westward-propagating ...
