Abstract: The linearized equation for the time-varying, axially symmetric circumferential component of the vorticity in a hurricane-like vortex closely resembles the classical Sawyer?Eliassen equation for the quasi-steady, diabatically ...

Abstract: piral cloud bands dominate tropical cyclones? appearance in satellite and radar images. It is generally accepted that at least some of them are vortex Rossby waves that propagate on the radial gradient of mean-flow-relative ...

Abstract: eta, the meridional gradient of planetary vorticity, causes tropical cyclones to propagate poleward and westward at approximately 2 m s?1. In a previous shallow-water linear model, the simulated vortex accelerated without ...

Abstract: An algorithm for location of hurricane centers by least squares using aircraft data has been developed. As the aircraft traverses the eye, lines of position normal to the wind are constructed each 100 m along its track. ...

Abstract: Hurricane Gilbert of 1988 formed an outer eyewall as it intensified rapidly toward a record minimum pressure of 888 hPa in the western Caribbean. The outer eyewall strengthened and contracted, while the inner eyewall showed ...

Abstract: Measurements of ozone (O3) concentrations obtained during aircraft eyewall crossings of Tropical Cyclones Floyd (September 1999) and Georges (September 1998) by NOAA P-3 hurricane research aircraft showed marked changes ...

Abstract: The Sawyer?Eliassen Equation (SEQ) is here rederived in height coordinates such that the sea surface is also a coordinate surface. Compared with the conventional derivation in mass field coordinates, this formulation adds ...

Abstract: This comment presents a detailed examination of the published model results of Kurihara and Kawase in an attempt to clarify the role of wave-CISK in the development of tropical cyclones. Kurihara and Kawase's model simulates ...

Abstract: AbstractA modified version of the Sawyer?Eliassen equation is applied to determine the impact of periodic diurnal heating on a balanced vortex. The TC diurnal cycle is a coherent signal that arises in the cirrus canopy. ...

Abstract: A nonlinear, two-layer, vortex-tracking semispectral model (i.e., Fourier transformed in azimuth only) is used to study the evolution of dry, but otherwise hurricane-like, initially tilted vortices in quiescent surroundings ...
