Climate change, tropical cyclones, and ENSO

Abstract

Climate models proliferated to account for the changes in tropical cyclone characteristics. Two such models are presented. One is a limited-area climate model with a horizontal resolution of 30 km and could give a good simulation of the climatology of tropical cyclone formation using only the observed tropical cyclone threshold criterion, namely 10-m wind speeds greater than 17 m s-1. The other model which is undergoing development incorporates an improved climate model simulation of ENSO coupled to a "strecthed" variable-resolution grid. The model will be used to generate a tropical cyclone climatology with the hope of answering questions about the links between climate change, climate vari..
