CMS-Flow:Wind Pressure

Wind

In CMS-Flow the wind shear stress is calculated as

     ${\tau }_{Wx}={\rho }_a{C}_{d}W<sup>2</sup>sin(\theta ),{\tau }_{Wx}={\rho }_a{C}_{d}W<sup>2</sup>cos(\theta ),$  

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
