Super-Parameterization of Boundary Layer Roll Vortices in Tropical Cyclone Models.

摘要

The long term goals of this effort are to Advance the parameterization of the atmospheric boundary layer in high wind conditons to improve the forecast of tropical cyclone (TC) intensity and Develop and implement a new parameterization of the effects of roll vortices into the U.S. Navy s operational COAMPS-TC prediction system. The objectives of this project are: To develop a new methodology for explict representation of roll vortices in TC models. To investigate the mechanisms leading to the formation of roll vortices in TC conditions and to assess their effects on the structure and intensity of TCs. To investigate the interaction between the surface processes and the BL processes and to assess their effects on TC intensity and structure preditions.
