Description
Neutral drag coefficient from Large and Yeager 2004 is not adapted to tropical cyclone forcing (key_cyclone), leading to very high (probably unrealistic) windstress under cyclones. One solution is to use Large and Yeager 2009 formulation.
In sbcblk_core.F90 and for TURB_CORE_2Z, I guess changes could be as follows :
! Large and Yeager 2009 formulation
WHERE (dU10 >= 33 )
Cd_n10 = 0.00234
ELSEWHERE
Cd_n10 = 1.e-3*( 2.7/dU10 + 0.142 + dU10/13.09 -3.14807e-10 * dU106 )
END WHERE
instead of
! Large and Yeager 2004 formulation
Cd_n10 = 1E-3*( 2.7/dU10 + 0.142 + dU10/13.09 )
Cd_n10 = 1E-3*( 2.7/dU10 + 0.142 + dU10/13.09 )
