Abstract: Data presented indicate that severe thunderstorm areas may become anchored to intense, boundary- layer convergence zones. In such cases. the mean cloud-layer wind vector has little relation to the movement of regions of ...

Abstract: Several examples of Geostationary Operational Environmental Satellite (GOES) visible satellite images depicting cloud features often associated with the transition to, or intensification of, supercell thunderstorms are ...

Abstract: An investigation of severe storms that occurred on 23 May 1974 in central Oklahoma reveals interesting information on the multifaceted role of thunderstorm-produced gust fronts. The data reveal that the interaction of ...

Abstract: This note provides examples of how geostationary satellite data can be applied to augment other data sources in tracking warm, moist air masses as they move northward from the Gulf of Mexico. These so-called returning air ...

Abstract: Satellite images are presented to illustrate an interesting interaction that occurred between a severe thunderstorm and a mesoscale feature that originated in its nearby environment. Immediately following that interaction, ...

Abstract: More than a decade ago, a study was published that identified a short list of precursor conditions for severe thunderstorms on the High Plains of the United States. The present study utilizes data from the summer months ...

Abstract: Tornadic storms that occurred over northeastern Kansas and northern Missouri on 4 July 1995 are examined by combining the latest in National Weather Service technology with more routine datasets. The analysis provides an ...

Abstract: A large, low-level thunderstorm outflow boundary was observed as it exited from beneath the cirrus canopy of Hurricane Luis following a period of intense convection in the storm?s eyewall. A description of the feature and ...

Abstract: Conditions leading up to an outbreak of severe hailstorms in northeast Colorado are examined using satellite and surface data. A persistent mesoscale ridge of surface-high pressure, caused by outflow from a mesoscale- ...

Abstract: During the late afternoon and early evening of 6 June 1990, a series of severe thunderstorms produced nine tornadoes and numerous incidents of large hail on the High Plains of eastern Colorado. While the morning synoptic ...
