Abstract

Experiments with insertion of height data in a free surface spectral model were conducted to explain the effectiveness of local geostrophic correction of the wind field in accelerating the assimilation of the height data by the model. It is shown that the local geostrophic correction projects most of the inserted data on to the slow manifold of the model.
