Climate model simulations of the effects of the El Chichon eruption
Contenido principal del artículo
Resumen
Se emplea un modelo climático de balance de energía para calcular el efecto de la erupción del 4 de abril de 1982 del volcán ~ Chichón sobre la temperatura del aire para los siguientes 10 años. El máximo enfriamiento de 1.0 - 1.4 C ocurre en el Polo Norte en la primavera y el otoño de 1984 y 1985. La respuesta promedio anual en el Hemisferio Norte es mayor en 1984 y 1985 con un enfriamiento de 0.4 - 0.5 C. Se presentan las respuestas de la tierra y del océano por separado corno funciones de latitud y época del año. Los patrones particulares que resultan son causados por las retroalimentaciones del albedo de la nieve y la inercia térmica del hielo. Estos resultados tienen implicaciones de importancia para la detección del cambio de clima inducido por el CO2.
