Four-dimensional data assimilation in the monsoon region. Part I: experiments with wind data.

A limited area primitive equation model is used to study the feasibility of four dimensional data assimilation in the monsoon region and studies the applicability of several assimilation techniques currently employed in global models. Tries to determine how the model atmosphere responds to the insertion of asynchronous data and its impact on the assimilation prediction cycle and also what assimilation strategies work best for limited area models in the tropics.
