Wind

In CMS-Flow the wind shear stress is calculated as

      

The wind drag coefficient is calculated using the Hsu (1988)

      


Symbol Description Units
Wind shear stress Pa
Atmospheric density (~1.2 kg/m^3) kg/m^3
Wind drag coefficient none
10-min averaged wind speed at 10 m above the sea surface m/sec
Wind direction m/sec
