Estimation of Tropical Cyclone Wind Using a Modifi ed Jelesnianski’s Pressure Model

บทคัดย่อ

Abstract

In this paper, a parametric wind model for estimation of the gradient wind speed of tropical cyclone is developed.The model is based on the gradient wind model and the Jesnianki’s pressure model. The model parameters are the pressure of the storm center, the pressure of environment and the radius of maximum wind speed. The case studyis typhoon Vamei (2001). Results from the model show that the gradient wind speed of tropical cyclone has good accuracy.
