Thermodynamic Aspects of Tropical Cyclone Formation
Publisher: American Meteorological Society
Abstract: he thermodynamic aspects of tropical cyclone (TC) formation near the center of the wave pouch, a region of approximately closed Lagrangian circulation within the wave critical layer, are examined through diagnoses of a ...
Characteristics of Convective Processes and Vertical Vorticity from the Tropical Wave to Tropical Cyclone Stage in a High-Resolution Numerical Model Simulation of Tropical Cyclone Fay (2008)
Publisher: American Meteorological Society
Abstract: he statistics of convective processes and vertical vorticity from the tropical wave to tropical cyclone stage are examined in a high-resolution simulation of Tropical Cyclone Fay (2008). The intensity of vertical velocity ...
Role of Cumulus Congestus in Tropical Cyclone Formation in a High-Resolution Numerical Model Simulation
Publisher: American Meteorological Society
Abstract: he role of cumulus congestus (shallow and congestus convection) in tropical cyclone (TC) formation is examined in a high-resolution simulation of Tropical Cyclone Fay (2008). It is found that cumulus congestus plays a ...
What is the Key Feature of Convection Leading up to Tropical Cyclone Formation?
Publisher: American Meteorological Society
Abstract: AbstractInfrared brightness temperature data are used to investigate convective evolution during tropical cyclone (TC) formation in a quasi-Lagrangian framework. More than 150 named Atlantic storms during 1989?2010 were ...
North Atlantic Rossby Wave Breaking during the Hurricane Season: Association with Tropical and Extratropical Variability
Publisher: American Meteorological Society
Abstract: AbstractThis study explores the connection of Rossby wave breaking (RWB) with tropical and extratropical variability during the Atlantic hurricane season. The exploration emphasizes subtropical anticyclonic RWB events over ...
Revisiting the Relationship between Polar Lows and Weather Regimes

Moisture and Precipitation Evolution during Tropical Cyclone Formation as Revealed by the SSM/I–SSMIS Retrievals
Publisher: American Meteorological Society
Abstract: he simultaneous precipitation and column water vapor retrievals from the SSM/I and SSMIS passive microwave instruments were used to examine the convective and moisture evolution during tropical cyclone formation. Using a ...
A Numerical Study of the Impacts of Dry Air on Tropical Cyclone Formation: A Development Case and a Nondevelopment Case
Publisher: American Meteorological Society
Abstract: he impacts of dry air on tropical cyclone formation are examined in the numerical model simulations of ex-Gaston (2010) and pre-Fay (2008). The former, a remnant low downgraded from a short-lived tropical cyclone, can be ...
Interannual Variability of the Atlantic Hadley Circulation in Boreal Summer and Its Impacts on Tropical Cyclone Activity
Publisher: American Meteorological Society
Abstract: novel method was developed to define the regional Hadley circulation (HC) in terms of the meridional streamfunction. The interannual variability of the Atlantic HC in boreal summer was examined using EOF analysis. The ...
