Numerical Analysis of Atmospheric and Oceanic External Forces of 2008 Cyclone Nargis

Abstract

This article describes the application of the coupled process-based cyclone surge simulation model to the simulation of cyclone Nargis. The storm surge simulation has been conducted by a dynamically coupled atmosphere-ocean-land model. It has been made clear the following major results. (1)Gulf of Martaban has the very dangerous geographical feature characteristic for high storm surge. (2)The computed maximum storm surge anomaly was 7m in the inner bay with 1.5 m increased tide caused by wave breaking stress. (3) A possibility of the compound disaster with a heavy rain flood, high tide and high wave was pointed out.
