Abstract:

The long-term goals of this research are to deploy and use autonomous ocean borne instruments to document the ocean response and the structure and strength of air-sea interaction to hurricane strength winds. These data are used for both real-time monitoring of hurricanes as well as for the improvement of the performance of ocean and atmosphere coupled models. In late August of 2003 and 2004 during the CBLAST Hurricane Study, a total of 50 drifters were successfully air-deployed in front of class 4 hurricanes Fabian and Frances. In July 2004, NAVAIR had placed wind-drifters in the hurricane alley north of the Antilles, which significantly enhanced the data set from a class 1 hurricane, Jeanne during the third week of September 2004. The objectives of this research are to perform a analysis of the ocean near surface circulation forced by these hurricanes and b joint analysis of drifter and profiling float data sets in the response of the water column at depth. A principal anticipated result of these analyses would be an estimation of the stress on the ocean surface as a function of hurricane strength wind speed. We wish to answer the question What is the wind dependence of the drag coefficient for winds over 30msec
