Role of Vortex Rossby Waves on Tropical Cyclone Intensity

Abstract

The long-term goal of this project is to improve the prediction of tropical cyclone (TC) genesis and intensity changes through improved understanding of the fundamental mechanisms involved. Accurate prediction of TC intensity changes is critical to Navy mission and civilian activities. Significant gains have been made in the TC track prediction over the past three decades. The intensity forecast, however, has shown very little improvement during the same period. A main factor contributing to the lack of skill in the prediction of TC intensity is the inadequate understanding of complicated mechanisms involved. These mechanisms include internal dynamic and thermodynamic processes, external forcing, and scale interactions. Only after we understand these processes, are we then able to tackle the weaknesses in the model simulations and forecasts.
