Mendoza Biología entrainment Gulf of México atmospheric forcing sea surface temperature mixed layer numerical model A model for the mixed layer of the Gulf of México has been used to determine the effect that an idealizedcyclonic vortex has in the sea surface temperature. The model consists of the equations of conservation ofthermal energy and this of balance between mechanical energy and thermal energy, last based on the Kraus-Turner theory; both equations are vertically integrated in the mixed layer. As atmospheric forcing, we prescribe the surface wind associated with an axially-symmetric cyclonic vortex characterized by two parameters: themaximum tangential velocity and the radius at which that velocity is reached. The values of these twoparameters, which depend on the position of the vortex, correspond to two cases: hurricane Hilda, whichcrossed the central part of the Gulf of México between September 29 and October 3, 1964 and hurricane Gilbertwhose trajectory between 11 and 17 September, 1988 crossed the Caribbean Sea, the Yucatán Peninsula andthe southwest Gulf of México. The results show that a cyclonic vortex with such characteristics, produceduring its passage by the sea vertical turbulent water transport through the thermocline (entrainment) that isable to cool down the mixed layer in several degrees and increases the thermocline depth in several meters, inagreement with the observations. 2006 artículo científico 0187-6236 https://www.redalyc.org/articulo.oa?id=56519204 en http://www.redalyc.org/revista.oa?id=565 Atmósfera application/pdf Universidad Nacional Autónoma de México Atmósfera (México) Num.2 Vol.19 |
