Abstract

This research simulates the development of typhoon Xangsane (0615) in terms of vertical vorticity of the storm.The Weather Research and Forecasting (WRF) model is used in the simulations. The Rankine vortex wind bogussing is used to enhance the weak observed wind speed before input into WRF model. Results show that with bogus wind, the simulation provides accurate timing of the intensification of Xangsane from tropical to typhoon.
