Abstract

The eastern Pacific Ocean basin responds to both short-term weather events such as hurricanes (Raymond et al. 2004) and gap winds (Kessler 2002), as well as forming the Costa Rica Dome (Hofmann et al. 1981) through the mean wind stress and curl. The EPIC data acquired during EPIC in addition to the TAO moorings (Cronin et al. 2002) and satellite altimetry must be used to improve our understanding of the effects of transient and mean wind conditions on the upper ocean and assess the impact of warm rings on atmospheric processes. Imp licit in satellite algorithms is the acquisition ocean structure measurements including the moored TAO array data (Cronin et al. 2002). The integrated thermal structure (OHC) is a more effective measure of the ocean's influence on storm intensity than just SST. In this context, upper ocean structure must be accurately accounted for in the models with realistic ocean mixing parameterization schemes based on measurements. While thin OML deepen and cool quickly through shear instability (Price 1981; Shay 2001; Jacob et al. 2000) and induce negative feedback to the atmosphere, the strong stratification at the base of the OML and the long inertial periods of 2 to 3 days may preclude significant cooling during genesis and passage over the EPAC warm pool. Thus, mo re heat is available to the storm or reduced negative feedback as the upper ocean does not significantly cool that quickly.
