Abstract: The synoptic-scale flow during tropical cyclogenesis and cyclolysis over the North Atlantic Ocean is investigated using compositing methods. Genesis and lysis are defined using the National Hurricane Center (NHC, now known ...

Abstract: An analysis is presented of prominent mesoscale structure in a moderately intense cyclone with emphasis on a long-lived, large-amplitude inertia?gravity wave (IGW) that moved through the northeastern United States on 4 ...

Abstract: Motivated by outstanding issues from a previous case study of a midlatitude cold surge that affected Mexico and Central America, the climatology of Central American cold surges is examined in this paper. An independently ...

Abstract: A limited regional climatology of cyclones with and without inverted troughs that form in the Colorado region is presented along with case study results from two major cyclone events in which an inverted trough plays a ...

Abstract: Hurricane Opal intensified rapidly and unexpectedly over the Gulf of Mexico between 1800 UTC 3 October and 1000 UTC 4 October 1995. During this period the storm central pressure decreased from 963 to 916 hPa and sustained ...

Abstract: In the wake of the eastern United States cyclone of 12?14 March 1993, a cold surge, originating over Alaska and western Canada, brought northerlies exceeding 20 m s?1 and temperature decreases up to 15°C over 24 h into ...

Abstract: The incipient stages of the 12?14 March 1993 ?superstorm? (SS93) cyclogenesis over the Gulf of Mexico are examined. Noteworthy aspects of SS93 include 1) it is the deepest extratropical cyclone ever observed over the Gulf ...

Abstract: The results of a multiscale analysis of the 12?14 March 1993 superstonn (SS93) over eastern North America are presented. A time sequence of overlapping 10-day time-mean 5OO-hPa geopotential height and anomaly composites ...
