Estudio del índice de aerosoles del TOMS para la predicción de las intrusiones de polvo sahariano en las Islas Canarias

Abstract

Se realiza una climatología de las invasiones de polvo sobre las Islas Canarias a partir de la serie de imágenes de índice de aerosoles del TOMS (Total Ozone Mapping Spectrometer) de NASA’s Goddard Space Flight Center a bordo del Nimbus7, pudiendo diferenciar tres periodos diferentes durante el año: Desde enero y hasta finales de mayo las intrusiones de polvo no son muy frecuentes pero pueden llegar a ser intensas, desde finales de mayo hasta mediados de octubre son más frecuentes e intensas y desde mediados de octubre hasta diciembre son poco frecuentes y de menor intensidad. En general las intrusiones de polvo en invierno afectan más a la población porque el polvo entra en niveles más bajos que en verano. Se presenta una nueva herramienta para predecir las invasiones de polvo sobre las islas Canarias que combina información del TOMS/EarthProbe y de las retrotrayectorias previstas calculadas con el modelo numérico HIRLAM, mostrándose su utilidad.

Ponencia presentada en: V Simposio Nacional de Predicción, celebrado en 2001 en Madrid.
