Abstract: The intensity or magnitude of a given heavy precipitation event is typically associated with the greatest point precipitation total. The scale or size of the heavy precipitation region, however, is important because it ...

Abstract: Much of the previous work on cold-air outbreaks has examined the synoptic development associated with small samples of strong outbreaks. In this study, a synoptic climatology of cold-air outbreaks is developed from a large ...

Abstract: Best track tropical cyclone data are examined for the period 1950?96 to estimate the landfall times of all tropical storms and hurricanes over the coastal margins of the eastern United States. The analysis reveals a marked ...

Abstract: Previous research has established links between heavy rainfall and a wide variety of synoptic features and parameters. In this study, 312 heavy rainfall events are identified over the southeastern United States and used ...

Abstract: The synoptic patterns and boundary layer conditions over a range of antecedent periods associated with the summertime hot events for the years 1951?93 are examined. A hot event is defined as a single day with the highest ...

Abstract: Cloud-to-ground (CG) lightning data are used in this study to trace the daily patterns of thunderstorms in time and space across the topographically diverse southeastern United States. Four reoccurring patterns of thunderstorms ...

Abstract: Changes in the 500 mb circulation are examined near and during each of 141 explosive surface cyclogenesis cases during the period 1 September 1980 through 31 May 1987 (June through August excluded) over the western half ...

Abstract: The sequence of development and thermodynamic aspects of two strong cold air outbreaks over eastern North America during January 1977 are described. In the first outbreak, surface cyclogenesis occurs prior to the outbreak ...

Abstract: inter storms, namely snowstorms and ice storms, are a major hazard and forecasting challenge across central North Carolina. This study employed a trajectory approach to analyze the ingredients (i.e., temperature, moisture, ...
