Assimilating Data into a Circulation Model
Abstract
LONG-TERM GOALS: The long-term goal of this study is to build an integrated circulation observation/prediction system where a variety of remote and in situ field observations can be assimilated into a numerical model to provide near real-time nowcasting and forecasting capabilities in the nearshore. OBJECTIVES: Our objective is to construct an integrated modeling capability that will rely on advancements in both models and spatially dense measurements of nearshore currents. The system consists of an existing numerical model of the depth- and phase-averaged equations of motion governing the temporal and spatial evolution of the nearshore circulation ( zkan-Haller and Kirby, 1999), and will utilize observations of surface current patterns obtained using Particle Image Velocimetry (PIV) techniques applied to a video system (PI's Lippmann and Holland) as well as other remotely obtained data such as surf zone width or proxies for radiation stress gradients (PI Holman).
