Fundamental Studies In Tropical Cyclone Structure & Intensity Change
نویسنده
چکیده
Focusing on dynamical and thermodynamical processes germane to the hurricane’s core region, this research aims to obtain a more complete understanding of key atmospheric processes governing hurricane structure and intensity. This year (beginning May 2002) we have continued our work on the moist dynamics of the hurricane eye/eyewall and the dry dynamics of a hurricane-like vortex in vertical shear. New insight and discoveries have been advanced in both areas. These are summarized below.

The long-term goals and objectives of this research are to develop a more complete physical understanding of tropical cyclone (TC) intensity change processes. This year’s work focused on the following three areas: Determining the three-dimensional asymmetric dynamics of the TC core region; Testing hurricane maximum intensity theory; Analyzing the environmental influences on the intensification ...
متن کاملDynamical Control of Rapid Tropical Cyclone Intensification by Environmental Shears
Improve our understanding of the physical processes by which (a) 3-D environmental shears, in particular the low-level meridional shear and upper-level vertical shear affect inner core structure and intensity, and (b) the mesoscale vortices, outer spiral rainbands, inner spiral rainbands, and the eyewall interact and affect TC development and intensity change. General questions to be addressed ...

متن کاملUnderstanding Impacts of Outflow on Tropical Cyclone Formation and Rapid Intensity and Structure Changes with Data Assimilation and High-resolution Numerical Simulations
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 lowto 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 la...

A long-term goal of this research is to improve dynamical prediction of tropical cyclones using ensemble methods for making analyses and forecasts. A second goal is to use the information contained in ensemble analyses and forecasts to improve basic understanding of tropical cyclone dynamics. Finally, a third goal is to use ensemble-based sensitivity analysis to target observations for tropical...
