New parameterization of air-sea exchange coefficients and its impact on intensity prediction under major tropical cyclones.

ABSTRACT: Understanding and quantifying air-sea exchanges of enthalpy and momentum fluxes are crucial for the advanced prediction of tropical cyclone (TC) intensity. Here, we present a new parameterization of air-sea fluxes at extreme wind speeds from 40 m s^-1 to 75 m s^-1, which covers the range of major TCs. Our approach assumes that the TC can reach its maximum potential intensity (MPI) if there are no influences of external forces such as vertical wind shear or other environmental constraints.This method can estimate the ratio of the enthalpy and momentum exchange coefficient (C _k/C _d) under the most intense TCs without direct flux measurements. The estimation showed that C _k/C _d increases with wind spee
