Ocean Data Assimilation and the Moan Filter：Spatial Regularity
Ocean Data Assimilation Moan Filter Regularity
2009/1/8
Ocean circulation models are infinite-dimensional dynamical systems. If the Kalman filter is used to assimilate data into such systems, then their infinite-dimensionality must be recognized. In other ...
Aspects of Geostrophic Adjustment during Tropical Ocean Data Assimilation
Tropical Ocean Data Assimilation Geostrophic Adjustment
