The microphysical processes associated with the growth of cloud and precipitation particles during two stable orographic storms are identified.

A mountain lee wave field study program using satellite photographs, superpressure-balloon trajectories, ground-based cloud photography, and rawinsonde flights is evaluated.

This study focuses upon the mechanisms by which mountains and synoptic weather systems interact to produce characteristic orographic cloud systems. In each of the three case studies, a synoptic cloud component, an orographic cloud component, and a convective cloud component were identified through the analysis of rawinsonde data, vertically pointing radar data, and visual observations.

This study investigates the performance of both the Nested Grid Model (NGM) and Colorado State University's Regional Atmospheric Modeling System (RAMS) for the 29-30 March 1991 Front Range storm. Through this investigation, a better understanding of both models efficiency and limitations can be assessed as they simulate the multicomponent nature of winter storms in Colorado's mountainous terrain.

Satellite photographs during the summer months frequently reveal a weather situation in which strong convective development is observed over the Rocky Mountains and several hundred kilometers to the east of the mountains, while the region immediately to the lee is essentially cloud free. It is proposed that an orographically induced mesoscale wave phenomenon may produce this situation.
