The Extratropical Transition of Tropical Cyclones
The objective is to investigate the physical processes that occur as a tropical cyclone interacts with the environment such that intensity and structure changes occur. Specific interactions being studied are with baroclinic environments in the midlatitudes during extratropical transition. During extratropical transition, radical changes to the storm structure occur as vertical wind shear and in...
متن کاملThe Dynamics of Extratropical Oceanic Cyclones
A temperature structure appropriate for maritime areas is employed to find exact solutions to the non-linear quasi-geostrophic omega and vorticity equations, using a procedure similar to that used in a quasigeostrophic model by Sanders (1971). Results are qualitatively similar to those found in the latter model, and thus, are consistent with the traditional baroclinic stability theory. The prin...
متن کاملMultiple satellite observations of cloud cover in extratropical cyclones
[1] Using cloud observations from NASA Moderate Resolution Imaging Spectroradiometer, Multiangle Imaging Spectroradiometer, and CloudSat-CALIPSO, composites of cloud fraction in southern and northern hemisphere extratropical cyclones are obtained for cold and warm seasons between 2006 and 2010, to assess differences between these three data sets, and between summer and winter cyclones. In both ...
متن کاملCan Climate Models Capture the Structure of Extratropical Cyclones?
Composites of wind speeds, equivalent potential temperature, mean sea level pressure, vertical velocity, and relative humidity have been produced for the 100 most intense extratropical cyclones in the Northern Hemisphere winter for the 40-yr ECMWF Re-Analysis (ERA-40) and the high resolution global environment model (HiGEM). Features of conceptual models of cyclone structure—the warm conveyor b...
متن کاملScenarios in the development of Mediterranean cyclones
The Mediterranean is one of the most cyclogenetic regions in the world. The cyclones are concentrated along its northern coasts and their tracks are oriented more or less west-east, with several secondary tracks connecting them to Europe and to North Africa. The aim of this study is to examine scenarios in the development of Mediterranean cyclones, based on five selected winter seasons (October...
