Description And Dynamics Of 50-Day Oscillations In The Western Tropical Region Of The Cme Model, Julie Lorraine Mcclean

OES Theses and Dissertations

The WOCE Community Modelling Effort (CME) general circulation model of the north Atlantic was used to investigate the behavior, nature and dynamics of 50-day oscillations seen in the meridional component of velocity between 35° and 55°W and between 5° and 11°N. Validation studies showed that the model reproduced the surface circulation in this area with a reasonable degree of accuracy, in particular, the characteristic seasonal variability. From June to December, the North Brazil Current (NBC) retroflects to form the western arm of the North Equatorial Countercurrent (NECC). Associated with the NECC is a standing meander pattern which extends from the …

Heat Storage And Transport Processes In The Tropical Atlantic Ocean, Andras Kapolnai

OES Theses and Dissertations

Heat storage and transport processes of the tropical Atlantic play an important role in the climate of three continents. The exploration of how the warm water mass maintenance in the equatorial basin depends on various external factors is therefore an important task. This study examines the annual cycle of the warm water mass formation and its transport in the equatorial Atlantic through the interaction of the atmospheric and oceanic boundary layers. Key features of the model are the sea level wind field, equatorial upwelling rate and escape transport of the formed warm water out of the equatorial basin.

The model …
