The Life Cycles of Extratropical Cyclones
1999This monograph contains expanded versions of the invited papers presented at the International Symposium on the Life Cycles of Extratropical Cyclones, held in Bergen, Norway, 27 June-1 July 1994. The symposium coincided with the 75th anniversary of the introduction of Jack Bjerknes's frontal-cyclone model presented in his seminal article "On the ...

The Extratropical Transition of Tropical Cyclones
2003Abstract : To improve tropical cyclone structure and intensity prediction through a research program combining high-resolution modeling and detailed observational studies to investigate physical processes by which the structure and intensity of a tropical cyclone are modified.

On the interaction of extratropical cyclones with topography
1997To better understand the role of mountains in lee cyclogenesis, two such cases which occurred during BASE (Beaufort and Arctic Storms Experiment) are simulated using the Mesoscale Compressible Community model (MC2). Both cases are shown to satisfy criteria for lee cyclogenesis, despite some ambiguity in its definition. The successful simulations reveal

On the relation of the number of extratropical cyclones to their sizes
Izvestiya, Atmospheric and Oceanic Physics, 2008Extratropical cyclones were identified on the basis of sea level pressure NCEP/NCAR reanalysis data for the Northern Hemisphere from 1948 to 2004. Cyclone positions were determined with a time interval of 6 h. Cyclone sizes were obtained with the use of a numerical scheme based on a rotation of the spherical coordinate system such that the pole of the ...

Boundary layer mechanisms in extratropical cyclones
Quarterly Journal of the Royal Meteorological Society, 2007AbstractThis paper revisits the mechanism for the interaction of the boundary layer with extratropical cyclones. Two diagnostic approaches are compared: Ekman pumping and potential vorticity. Ekman pumping derives from the boundary layer stress which induces convergence and ascent.

Organization of Clouds and Precipitation in Extratropical Cyclones
1990A number of models accounting for the distribution of cloud and precipitation in extratropical cyclones were proposed during the 19th and early 20th centuries. A history of these has been recounted by Bergeron (1959, abridged version in Bergeron 1981) and also by Ludlam (1966) in his inaugural lecture as professor of meteorology.
