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 change is critical to Navy missions and civilian activities in coastal areas. Significant gains have been made in the TC track prediction over the past three decades. The intensity forecast, however, has shown very little progress during the same period. A main factor contributing to the lack of skill in the prediction of TC intensity is the inadequate understanding of the complicated mechanisms that are involved. These mechanisms include internal dynamic and thermodynamic processes, external forcing, and scale interactions. Only after we understand these processes, will we then be able to tackle the weaknesses in model simulations and forecasts.
