Understanding Impacts of Outflow on Tropical Cyclone Formation and Rapid Intensity and Structure Changes with Data Assimilation and High- Resolution Numerical Simulations.

摘要

Understanding the processes that contribute to tropical cyclone (TC) formation, intensity and structure changes is essential for improving the predictability of TCs. Previous studies have focused mostly on the low- to mid- level processes leading to TC formation and rapid intensity and structure changes. The influence of upper-level atmospheric processes, especially the evolution of the outflow layer has not received much attention until recently. Therefore, the long-term goal of the proposed work is to improve our understanding and prediction of the tropical cyclone outflow layer, its evolution, and relation to tropical cyclone (TC) formation and intensity and structure changes.
