Resumen
Con el fin de explorar la influencia de los océanos tropicales sobre las Anomalías de la Temperatura Superficial del Mar (ATSM) de la costa pacífica centroamericana, se ajustó un modelo de función de transferencia a las series de ATSM de los Golfos de Tehuantepec, Papagayo, Panamá y Quepos, usando como variables independientes los índices Niño 3.4, Atlántico Tropical Norte y Sur. Estos modelos concluyeron que la principal influencia sobre la región, al compararla con los otros índices, la ejerce el índice Niño 3.4 pues mostró correlaciones positivas con todas las series de ATSM, lo cual refleja una influencia de este índice sobre la profundidad relativa de la termoclina frente a la costa del Pacífico centroamericano.
In order to explore the influence of the surrounding tropical oceans on the Central American Pacific coast, a Transfer Function Model was fixed to Sea Surface Temperature Anomalies (SSTA) of the Gulf of Tehuantepec, Papagayo, Panama and Quepos time series. As independent variables the following were used: Niño 3.4, Tropical North and South Atlantic indices. These models show that Niño 3.4 has the most important influence over the region when compared with the influence of the other indices, having positive correlation with all the SSTA series. It shows an influence of this index on the relative termocline’s depth in front of the Central American Pacific Coast.
