Variabilidad de la temperatura superficial del mar en el sureste del Atlántico Norte

Abstract

El objetivo de este trabajo es el estudio de las variabilidades de las magnitudes fisicas caracteristicas de la superficie del mar, asi como de su interaccion y forzamientos con las variables atmosfericas. Para ello se han seleccionado tres bases de datos que permiten un estudio sinoptico de la superficie del oceano; del sensor remoto AVHRR, los historicos COADS y los atmosfericos ECMWF. Dado el carácter del estudio, los datos en forma de escenas bidimensionales los reducimos al formato de series temporales. Estas se seleccionan en forma de malla regular que se extiende a toda la region. El analisis espectral de las series temporales lo realizamos en funcion de su estructura. Como resultado de este analisis hemos determinado la existencia de tres variabilidades de carácter regular: Una primera, generalizada en toda la region, de periodo anual, asociada a la estacionalidad. Una segunda, extedida en la zona central de la region, de periodo semianual, asociada a variaciones en la misma zona de la componente z del rotacional de la tension del viento. Una tercera, localizada al norte de Lanzarote, al sur de las Islas Canarias y en torno a Cabo Verde, de periodo cuatro años, asociada a variabilidades interanuales en el Atlantico Tropical.
