Role of the Indochina Peninsula Narrow Mountains in Modulating the East Asian-Western North Pacific Summer Monsoon

摘要

Unrealistic topographic effects are generally incorporated in global climate simulations and may contribute significantly to model biases in the Asian monsoon region. By artificially implementing the Arakan Yoma and Annamese Cordillera-two south-north-oriented high mountain ranges on the coasts of the Indochina Peninsula-in a 1 degrees global climate model, it is demonstrated that the proper representation of mesoscale topography over the Indochina Peninsula is crucial for realistically simulating the seasonality of the East Asian-western North Pacific (EAWNP) summer monsoon.
