Estimates of surface enthalpy and momentum fluxes at high winds speeds using the budget residual method: Results from CBLAST
Jeanne Davancens, MIT, Issy les Moulineaux, France; and K. A. Emanuel
In a steady, circularly symmetric vortex, the flow of enthalpy and angular momentum between the ocean and atmosphere can be estimated as that required to balance the (measured) flux of angular momentum into and energy out of annuli surrounding the vortex center. During CBLAST, very dense radial arrays of dropwindsondes were deployed across the eyewalls of Hurricanes Fabian and Isabel (2003) in an attempt to measure these fluxes, and surface fluxes were then inferred. results of the analysis off the Fabian data will be presented, focusing on estimates of the values of the exchange coefficients for momentum and enthalpy at very high surface wind speeds.
