Heat exchange
Storyboard

The exchange of heat between the atmosphere and the ocean refers to the process by which the atmosphere transfers or absorbs heat from the ocean, thereby equalizing the temperatures between the two.Ocean-Atmosphere Interactions of Gases and Particles, Peter S. Liss, Martin T. Johnson (eds.). Springer, 2014Chapter: Transfer Across the Air-Sea Interface

Equations

In the Monin-Obukhov Similarity Theory (MOST), the surface heat energy, represented by

$\rho_a c_p (T_z - T_0)$



is transferred to the water with the transfer coefficient $C_H$ and the air velocity $U_z$, resulting in the heat flux.

$ H_z = C_H \rho_a c_p ( T_z - T_0 ) U_z $
