Studies of Air-Sea Coupling as Part of CBLAST High 2006 Annual Report
Abstract
LONG-TERM GOALS. A question that came out of a study of satellite imagery from the hurricane Fabian data set was --- What process causes the cool SST in a hurricane wake to recover to pre-hurricane values? The recovery is quite rapid, in the Fabian case e-folding in five days, and so has a significant impact upon the inference of SST cooling using satellite data. OBJECTIVES. The major effort during 2006 was directed to two air-sea modeling projects; Hurricane-Ocean Interaction with S. Chen, which I will mention toward the end, and analysis of SST relaxation of the cool wake of hurricane, a collaboration with J. Morzel and P. Niiler. This report will emphasize the latter project. APPROACH. The method is first to document the SST cooling and recovery in observations -- the figure below has been derived from GOES IR imagery: This three-dimensional surface depicts SST as the up coordinate along a 400 km wide swath across the track of hurricane Fabian in the Sargasso Sea. The data at the left of the figure are pre-hurricane, and indicate SST that was rather warm and quasi-uniform, typical of the late summer subtropics.
