Geophysical Fluid Dynamics 



The NOAA Geophysical Fluid Dynamics Labo- 

 ratory (GFDL) has conducted a broad program of 

 research on mathematical modeling of the general 

 circulation of the atmosphere, the oceans, and the 

 ocean-atmosphere system throughout the entire 

 10-year period. With one of the world's largest and 

 fastest computers, GFDL scientists have investi- 

 gated the dynamics of geophysical fluids over a 

 wide range of time and space scales. The studies 

 are comprised of research on the structure and 

 circulation of planetary fluid systems — the tro- 

 posphere, the upper atmosphere, and the oceans.

Structure and Motion of the Oceans 



This program investigates the structure, veloci- 

 ty, extent, and variation of nearshore and ocean 

 currents in order to predict the measurement of 

 water, heat, living resources, and pollutants. This 

 work is an essential element in understanding the 

 ocean's role in climatic variations. Investigations 

 include: (1) studies of the time and space varia- 

 tions of currents and on the physical properties 

 and chemical characteristics of nearshore and 

 oceanic waters, utilizing current meters, drifting 

 instrumented buoys, satellite imagery, tide gages, 

 and water sampling devices: (2) studies using 

 deep-sea pressure gages to investigate the various 

 scales of motion in the ocean and the tidal modifi- 

 cations induced by the Continental Shelf: (3) 

 measurement of exchange rates among the Gulf 

 of Mexico, Caribbean Sea, and the Atlantic 

 Ocean and of the coastal discharge and dispersion 

 of pollutants.
