Subhrajit Rath The sensible heat flux is given as:

Qs = rhoair cp cs u10 (SST - Tair)

Here rhoair is the density of the air

cp is the specific heat of air

cs is the stability-dependent bulk transfer coefficient for heat (typically 10-3)

u10 is the surface wind speed sqrt(uwind^2 + vwind^2)

Tair is the surface temperature of air

SST is the sea surface temperature

QL = rhoair LecL u10 (q*(SST) - qair)

Le is the latent heat of evaporation

cL is the stability-dependent bulk transfer coefficient for water vapor (typically 1e-3)

q* is the specific heat of saturation which is a function of the SST.

qair is the specific humidity (in kg vapor per kg air)
