9 páginas, 4 figuras, 1 tabla [EN] The following hypothesis is exposed: Variations of the oceanic currents depend mainly on these two factors: (a) the variation of the solar energy flux; and (b) the energy dissipated from Earth's variable rotation. In oceanic currents having an E-W direction the main factor will be polar motion, but in currents N-S this factor will be variations of the solar energy flux. Peviously the authors had studied the effect of polar motion in marine ecosystems of the North Atlantic Ocean, where currents have a W-E main direction. Now an essay is carried out to test if in N-S currents the variation of the solar energy flux acts as a perceptible factor. Percent of decrease in solar constant and coefficient of variation for the first Empirical Orthogonal Function in the California Current, as an example of N-S current, have been used. Relationship between these two factors appears to be significant, and the time lag between changes of the solar energy flux and response of the current flow seems to be about 3-9 months. A seasonal variation of the velocity of the Kuroshio seems to confirm this solar energy role in oceanic currents [ES] Se expone la siguiente hipótesis: Las variaciones de las corrientes oceánicas dependen principalmente de estos dos factores: (a) la variación del flujo de la energía solar; y (b) la energía disipada de las variaciones de la rotación de la Tierra. En corrientes oceánicas con una dirección predominantemente E-O el factor principal será el movimiento polar, pero en las corrientes N-S este factor será las variaciones del flujo de la energía solar. Previamente los autores habían estudiado el efecto del movimiento polar en los ecosistemas marinos del Océano Atlántico norte, donde las corrientes tienen una dirección principal O-E. Ahora se realiza un ensayo para probar si en las corrientes N-S la variación del flujo de la energía solar actúa como un factor perceptible. Para ello se ha usado el descenso en la constante solar y el coeficiente de variación para la ...
