RISHeat Balance and Eddies in the Caribbean Upwelling System
Publisher: American Meteorological Society
Abstract: he upper-ocean heat budget of the Caribbean upwelling system is investigated during the onset of the Atlantic warm pool (June?September) using high-resolution observations of sea surface temperature and a high-resolution ...
Variational Assimilation of XBT Data. Part II. Sensitivity Studies and Use of Smoothing Constraints
Publisher: American Meteorological Society
Abstract: A linear reduced-gravity model of the tropical pacific is used to assimilate XBT data. The model cannot fit the data in the eastern equatorial Pacific for the whole assimilation period. Several experiments with real and ...
Variational Assimilation of XBT Data. Part 1
Publisher: American Meteorological Society
Abstract: A variations method based on the adjoint equation technique is used to assimilate data in a relatively simple linear reduced gravity model of the tropical Pacific. Real XBT data are used by identifying the depth of the ...
Lateral Friction in Reduced-Gravity Models: Parameterizations Consistent with Energy Dissipation and Conservation of Angular Momentum
Publisher: American Meteorological Society
Abstract: he f-plane reduced-gravity model has been extended with the parameterization of lateral friction in the momentum equations. The parameterization should preferably fulfill some requisites. One of them is that in the absence ...
Vertical Velocity and Vertical Heat Flux Observed within Loop Current Eddies in the Central Gulf of Mexico
Publisher: American Meteorological Society
Abstract: Sixteen months of observations from a surface-to-bottom mooring in the central Gulf of Mexico show that acoustic Doppler current profilers (ADCPs) are useful for directly measuring the vertical velocity within mesoscale ...
Surface Relative Dispersion in the Southwestern Gulf of Mexico
Publisher: American Meteorological Society
Abstract: urface dispersion properties in the southwestern Gulf of Mexico are studied by using a set of 441 drifters released during a 7-yr period and tracked for 2 months on average. The drifters have a drogue below the surface ...
Deep Currents in the Bay of Campeche
Publisher: American Meteorological Society
Abstract: ata from five moorings deployed in the Bay of Campeche during November 2007?July 2008 are used to analyze subinertial motions of waters below 1000-m depth. To the authors? knowledge, this is the first time such a comprehensive ...
Impact of Yucatan Channel Subsurface Velocity Observations on the Gulf of Mexico State Estimates

Seasonal and Interannual Modulation of the Eddy Kinetic Energy in the Caribbean Sea
Publisher: American Meteorological Society
Abstract: ariability of the mesoscale eddy field in the Caribbean Sea is analyzed over the period 1993?2009 using geostrophic anomalies derived from altimeter data and a high-resolution regional model. The Colombia Basin presents ...
Seasonal Modes of Surface Cooling in the Gulf of Guinea
Publisher: American Meteorological Society
Abstract: numerical simulation of the tropical Atlantic Ocean indicates that surface cooling in upwelling zones of the Gulf of Guinea is mostly due to vertical mixing. At the seasonal scale, the spatial structure and the time ...
