Consider steady flow described by the linearized horizontal momentum equations with a Rayleigh parameterization for the surface frictional drag (which introduces terms linearly proportional to the surface velocity in the momentum equations):
- fv =- ? ?/? x - ru
+ fu =- ? ?/? y - rv
Assuming the barotropic atmosphere and knowing geostrophic wind ( u g , v g ) at 500-mb is (30, 20) m/s, find the surface velocity. The Coriolis parameter f = 10^-4 s^-1 , and the frictional parameter r is 1/10 day^-1
