Diabatically Induced Secondary Flows in Tropical Cyclones. Part II: Periodic Forcing
Publisher: American Meteorological Society
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 ...
Synthesis of Vortex Rossby Waves. Part I: Episodically Forced Waves in the Inner Waveguide
Publisher: American Meteorological Society
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 ...
Synthesis of Vortex Rossby Waves. Part II: Vortex Motion and Waves in the Outer Waveguide
Publisher: American Meteorological Society
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 ...
Reanalysis of the 1954-1963 Atlantic Hurricane Seasons
Publisher: American Meteorological Society
Abstract: he Hurricane Database, HURDAT2, is the main historical archive of all tropical storms, subtropical storms, and hurricanes from 1851 to the present in the North Atlantic Basin, which includes the Caribbean Sea and Gulf of ...
Objective Determination of Hurricane Tracks from Aircraft Observations
Publisher: American Meteorological Society
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. ...
The Concentric Eyewall Cycle of Hurricane Gilbert
Publisher: American Meteorological Society
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 ...
Ozone Measurements from Eyewall Transects of Two Atlantic Tropical Cyclones
Publisher: American Meteorological Society
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 ...
Diabatically Induced Secondary Flows in Tropical Cyclones. Part I: Quasi-Steady Forcing
Publisher: American Meteorological Society
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 ...
Comment—An Interpretation of Kurihara and Kawase's Two-Dimensional Tropical-Cyclone Development Model
Publisher: American Meteorological Society
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 ...
Reanalysis of the 1954–63 Atlantic Hurricane Seasons
Publisher: American Meteorological Society
Abstract: AbstractThe National Hurricane Center (NHC) ?best track? hurricane database (HURDAT2) is the main historical archive of all tropical storms, subtropical storms, and hurricanes from 1851 to the present in the North Atlantic ...
