Near Real-time Outputs from the University of South Florida Indian Ocean Wind-Driven Circulation Model

Listed in NASA Earthdata CMR

This directory contains a "quick-look" hindcast of the Indian Ocean wind-driven circulation from a numerical ocean model being run at USF using near-real-time observed winds.

Description

The model products are produced under support from the Office of Naval Research and the National Science Foundation Chemical Oceanography Program. The model is that described in Jensen (1991) as modified by Jorge Capella to include a finer spatial resolution, an improved bathymetry, and an extended domain.

The present version of the model has 4 layers, with the horizontal pressure gradient assumed to vanish in the lowest layer (the reduced gravity approximation). The mean layer depths are: layer 1: 0 - 200 m; layer 2: 200 - 450 m; layer 3: 450 - 850 m. The model domain covers the Indian Ocean basin from 30 degrees S to 26 degrees N and from 35 degrees E to 120 degrees E at a resolution of 1/12 degree in latitude and longitude.

A 20-year integration, driven by climatological monthly mean winds from the FSU analysis, has been used to "spin-up" the model. Using the end of this 20-year integration as an initial condition, the model was run using the FSU monthly mean real-time winds for the period January 1977 through December 1991. This integration has been updated through the 16th of the most recently ended month using the FSU "quick-look" winds to provide a near-real- time estimate of conditions in the Indian Ocean.

Model output and images are available via anonymous ftp to "ftp://kelvin.marine.usf.edu" The wind stress fields used to drive the ocean model are compiled by David Legler and Jim O'Brien at Florida State University. Monthly mean wind fields are derived from all volunteer observing fleet ship reports that are received during each month via the GTS. The fields consist of monthly mean pseudostress (vector wind times wind speed) components objectively analyzed on a 1 degree by 1 degree grid using the method of Legler et al. (1988).

About 6 months after the end of the year, all the monthly mean fields are re- analyzed using additional data that is received in "delayed-mode" to produce a research-grade product. These data now cover the period from January 1977 through the end of the most recent month and are available on the Internet via anonymous ftp to "ftp://coaps.fsu.edu" (128.186.157.25).
