Dynamics of Forced Coastal-Trapped Disturbances
Abstract
The long-term goal of this project is to improve our ability to understand and predict meteorological conditions in the coastal marine atmospheric boundary layer. The objective of this project is to investigate the dynamics of coastal marine atmospheric boundary layer winds including the generation and propagation of coastal-trapped disturbances and their interaction with coastal orography and with orographically-modified ambient winds. The approach taken in this project is to obtain analytical and numerical solutions of idealized mathematical models of the marine atmospheric boundary layer and to compare these solutions to observations and to results from more complex models. Numerical and analytical models of the generation, propagation, and decay of linear and nonlinear coastal-trapped disturbances have been studied. Mesoscale simulations of the interaction of continuously stratified, hydraulically supercritical and transcritical flow with coastal orography have been carried out and analyzed, yielding new insight into the dynamics of coastal winds. Hydraulically transcritical model flows have been computed for comparison with observational data from the 1996 Coastal Waves Experiment along the California coast.
