Abstract:A simple evaporative cooling scheme was incorporated into a dynamic model to estimate orographic precipitation in mountainous regions. The orographic precipitation model is based on the transport of atmospheric moisture and the quanitifiation of precipitable water across a 3D representation of the terrain from the surface up to 250 hPa.

Abstract:It has been demonstrated in Part I of this paper that synoptic-scale waves propagating around Antarctica are modified by the Antarctic topography such that they transport westerly angular momentum out of Antarctica. These transports are necessary to maintain a vigorous slope wind regime, which generates westerly angular momentum through surface friction.

Abstract:The effects of precipitation on the surface temperature and airflow over the island of Hawaii, which are not considered in previous studies, are presented. It is found that clouds and rains can modify the surface thermal fields and result in changes in the intensity of diurnal circulations and the timing of wind shifts from downslope (upslope) to upslope (downslope) flow at the surface in the early morning (late afternoon).

Abstract:The theory of mountain waves is usually discussed for the case of a steady background wind. Here, the consequences of a superimposed diurnal (or other periodic) background wind variation are considered in outline. They are found to be sufficiently complicated as to warrant avoidance in detailed case studies. They include, however, the production of freely propagating waves and may be of interest on that account for other purposes.
