CMS-Flow:Wind Pressure

Wind and Atmospheric Pressure

In CMS-Flow the wind shear stress is calculated as

     $\tau _{wind}=\rho _{a}C_{d}|W|W$  

where

Symbol	Description	Units
$\tau _{wind}$	Wind shear stress	Pa
$\rho _{a}$	Atmospheric density (~1.2 kg/m^3)	kg/m^3
$C_{d}$	Wind drag coefficient	none
$W$	10-min averaged wind speed at 10 m above the sea surface	m/sec
