As part of the ONR sponsored Coupled Boundary Layer/Air-Sea Transfer (CBLAST) - hurricane experiment, high resolution (40Hz) data collected by the NOAA WP-3D research aircraft measurements into major Hurricanes in the 2002-2004 seasons are analyzed. Turbulent fluxes of momentum and enthalpy are derived using the eddy correlation method in the hurricane force wind regime with surface wind speed up to 30 m/s. Bulk parameterizations of the momentum and enthalpy flux are developed. We also discuss the variability of the surface fluxes and exchange coefficients by storm quadrant according to the variation of stability and sea state.
