LONG-TERM GOALS
APPROACH Our approach is to implement a multifaceted observational program among several investigators to simultaneously measure air-sea fluxes using several independent methods while at the same time measuring two-dimensional surface wave spectra, as well as spray droplet spectra , in wind speed regimes ranging from 20-40 m/s, and possibly higher. The secondary goal is to use existing data sets to inter-compare various published wave-dependent bulk flux parameterizations, with and without wave age effects and with and without spray parameterizations, using never-before-available surface inputs from GPS dropsondes, AXBTs, model-generated as well as remotely-measured wave spectra and remotely-measured surface winds in gale- and hurricane-force conditions. Our strategy will be to obtain new parameterizations of momentum, heat and moisture fluxes from these observations including accurate estimates of the exchange coefficients as a function of wind speed and to estimate the modulation of the fluxes by fetch-limited wind waves, long-wavelength swell, sea spray and PBL secondary circulations, i.e.roll vortices.
