Further Research on Dynamics of Marine Atmospheres in Tropical Cyclones

Abstract

The University of the District of Columbia (UDC) has undertaken a basic research on dynamics of marine atmospheres in tropical cyclones with an objective of improving understanding of turbulence in cyclone vortices and efficiency of computer simulation for transfer of heat, moisture and momentum in marine planetary boundary layers of tropical cyclones. For this objective, UDC has performed the following four phases of effort: I. Develop a mathematical model, using the second order turbulent closure equations, for simulating planetary boundary layers of tropical cyclones over the sea surface; II. Calculate velocity, enthalpy and moisture distributions in planetary boundary layers of tropical cyclones over the sea surface; III. Develop and instrument a laboratory vortex chamber for measuring the air/water interface turbulence and heat, moisture and momentum transfer; and IV. Develop a graphics-oriented interactive finite-element compute model to simulate transfer of heat, moisture and momentum in marine planetary boundary layers of tropical cyclones. (SDW)
