Tropical cyclone track forecasts using a limited-area model: sensitivity to the lateral boundary conditions

Abstract

International audienceThe link between tropical cyclone track forecasts by Aladin-Réunion limited-area model and by its coupling model Arpege is investigated in the South-West Indian Ocean. A significant impact of the coupling model on the LAM tr ack forecasts is shown after the 2-days term, although the sensitivity to initial conditions remains predominant in some case
