The long-term goal of this research is to better understand and explain the initiation, propagation and demise of trapped atmospheric disturbances in the coastal marine boundary layer, particularly those which have been observed to occur along the US West Coast. In particular we wish to obtain a better understanding of how topographic variability along the west coast of North America influences the evolution, propagation, and decay of Coastal Trapped Disturbances CTDs. Emphasis is placed on examining the termination of events which observations to date suggest may occur in the vicinity of bends, such as Cape Mendocino and Cape Blanco. A secondary objective is to determine whether a reduced gravity model applied to these events in previous work is a good approximation of the coastal atmosphere during CTD events. It is anticipated that this improved understanding will lead to enhanced forecasting of CTDs and their impact.
