Abstract

A comparative performance of dynamic initialization (Dl) and static initialization (SI) schemes for balancing initial wind and pressure fields for primitive equation barotropic model in Indian region has been investigated. For the purpose of dynamic initialization experiment the set of model equations are integrated forward and backward around the initial time following Euler backward time differcnce scheme without restoration of any variable. For static initialization the nonlinear balance equation is solved to obtain the balance height field from non-divergent wind.

 

The results of initialization experiments from both the schemes are compared and discussed. The initial fields from DI scheme are found to be superior than those based on SI scheme.
