A parabolic model of drag coefficient for storm surge simulation in the South China Sea. [PDF]
Sci Rep, 2015 Drag coefficient (Cd) is an essential metric in the calculation of momentum exchange over the air-sea interface and thus has large impacts on the simulation or forecast of the upper ocean state associated with sea surface winds such as storm surges ...
