Abstract: The interaction of a basic state flow consisting of a planetary-scale easterly wave superimposed on a uniform easterly zonal wind with an isolated topographic feature is examined by numerical integration of the shallow ...

Abstract: The motion of a barotropic vortex in the vicinity of a large-scale topographic feature is examined through numerical integration of the shallow-water equations in an equatorial beta-plane channel. The topographic parameters ...

Abstract: The diurnal temperature cycle in the Phoenix, Arizona, metropolitan area, as represented in the fifth-generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale Model (MM5), is examined ...

Abstract: The evolutions of radially symmetric vortices and idealized easterly waves are compared using three simple convective parameterization schemes. The parameterizations are formulated for a model atmosphere consisting of three ...

Abstract: The interaction Of developing two-dimensional cold and warm frontal systems with a mesoscale mountain ridge is examined. The flow of the rotating model atmosphere is assumed to be inviscid, adiabatic, and Boussinesq. The ...

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 ...

Abstract: This paper describes a technique for photogrammetric analysis of stereo pairs of images that is applied to the study of orographic convection. The technique is designed for use with digital images and assumes detailed ...

Abstract: The linear problem of rotating, stratified, adiabatic, hydrostatic, Boussinesq airflow over a mountain ridge is solved analytically for the case where the spatially uniform, normally incident airflow is the sum of a steady ...

Abstract: The early stages of tropical cyclogenesis in the eastern Pacific Ocean are investigated in this case study, which is focused on the development of the initial circulation that eventually intensified into Hurricane Guillermo ...
