Synoptic Estimates of Waves and Currents via Real-Time Assimilation of In-Situ Observations

Abstract

The long term goal of this effort is to develop an improved nearshore wave and current modeling system in order to achieve better and more detailed short-term predictive estimates of nearshore oceanographic conditions over spatial scales on the order of kilometers and time scales of the order hours to days. The overall objective of this project component is to support the integration of a variational data assimilation capability into the nearshore wave and current model based on the extended-Boussinesq equations of Wei et al. (1996). The variational assimilation algorithm is being developed by Dr. Dave Walker at General Dynamics (Ann Arbor) under a separate award (N00014-00-D-0114-0007). The focus of the effort under the present award over the past year has been on identifying improvements in model physics that may be necessary for the success of data assimilation procedures.
