Abstract

The Penn State-NCAR mesoscale model (MM5) in an idealized configuration was used to investigate the structural development of the barrier jet along the U.S. West Coast and the interaction of landfalling systems with the barrier jet. Baroclinic wave simulations with an idealized ridge and plateau demonstrated the effect of terrain width on the landfalling systems. These simulations were then compared to one with realistic terrain to show the significant effect of the Rocky Mountain Range. Overall, results indicate that the upstream influence of the inland topography of western North America on landfalling fronts is an important element in producing the rapid upstream frontogenesis.
