RISModulation of Near-Inertial Oscillations by Low-Frequency Current Variations on the Inner Scotian Shelf
Publisher: American Meteorological Society
Abstract: Near-inertial oscillations (NIOs) on the inner Scotian shelf are studied using observations, a simple slab model, and two operational shelf circulation models. High-frequency radar and ADCP observations from December 2015 ...
Application of the Multigrid Data Assimilation Scheme to the China Seas’ Temperature Forecast
Publisher: American Meteorological Society
Abstract: Correlation scales have been used in the traditional scheme of three-dimensional variational data assimilation (3DVAR) to estimate the background (or first guess) error covariance matrix (the ? matrix in brief) for the ...
Application of the Sequential Three-Dimensional Variational Method to Assimilating SST in a Global Ocean Model
Publisher: American Meteorological Society
Abstract: A recursive filter or parameterized curve fitting technique is usually used in a three-dimensional variational data assimilation (3DVAR) scheme to approximate the background error covariance, which can only represent the ...
Medium- to Long-Term Forecasts of Sea Surface Height Anomalies using a Spatiotemporal Empirical Orthogonal Function Method
Publisher: American Meteorological Society
Abstract: A spatiotemporal empirical orthogonal function (STEOF) forecast method is proposed and used in medium- to long-term sea surface height anomaly (SSHA) forecast. This method embeds temporal information in empirical orthogonal ...
