Asimilación de la humedad del suelo en modelos numéricos

Authors: Ayuso, Juan José;

Asimilación de la humedad del suelo en modelos numéricos

Abstract

Se van a revisar brevemente algunos métodos de inicialización de la humedad del suelo utilizados por diferentes modelos numéricos, describiendo en particular el esquema denominado ASISBA (Bouttier y Mahfouf; 1993) que es el escogido por el grupo HIRLAM. Se indican algunas mejoras realizadas en la formulación analítica del esquema. Se realiza un experimento seco y otro húmedo con el sistema de predicción HIRLAM operativo en el INM junto con el esquema de asimilación propuesto y el esquema de parametrización ISBA basado en (Noilhan y Planton 1989, NP89), los resultados de los experimentos muestran un buen comportamiento conjunto de ambos esquemas.
