Description

A dynamical initialization procedure incorporating friction and simulated heating has been applied with the use of a global barotropic primitive equation model in spherical coordinates to the problem of initialization of small scale motions in the fluid. Special emphasis is given to Kelvin and Rossby-gravity waves centered on the equator. These types of waves cause considerable difficulty if any type of quasigeostrophic of balanced type of initialization is used. The results are very encouraging in the sense that if information concerning the wind fields associated with such waves is available the mass field can be recaptured quite well even if no information beyond its mean value is available. For operational purposes some combination of this method with present advanced balancing methods may be indicated.
