Abstract
In a series of 5 papers, we have confirmed the hypothesis that large- scale eddy fluxes of momentum associated with upper-level asymmetries in the wind field play a fundamental role in hurricane formation. They do this by inducing the radial circulation which draws warm, moist lower tropospheric air inward toward the center of the disturbance over a large fetch of ocean and pumps drier air out at higher elevations. In the studies by Challa and Pfeffer and Pfeffer and Challa we used Sundqvist's symmetric hurricane model, modified to include parameterized eddy fluxes of momentum, to investigate the role of such fluxes in hurricane formation. This paper describes our accomplishments in three major areas: A. The mechanism of hurricane formation, B. Diagnostic studies of wave-mean flow interactions in the atmosphere and C. Laboratory simulations of fundamental atmospheric processes. Keywords: Computerized simulation; Hurricanes.
