Abstract: A study of radar echoes associated with the tornadoes of the 3 April 1974 outbreak was performed to evaluate the usefulness of echo shape as an indicator of tornadic thunderstorms. The hook shape was usually successful in ...

Abstract: Horizontal divergence, relative vorticity, kinematic vertical velocity, and geostrophic and ageostrophic winds are computed from Colorado profiler network data to investigate an upslope snowstorm in northeastern Colorado. ...

Abstract: The occasional occurrence of wintertime mesoscale lake vortices is documented. The vortices are readily discernible in satellite imagery, in which they take one of three forms: a miniature comma cloud, a swirl of cloud ...

Abstract: This paper presents results from pilot studies of the use of model-generated hourly soundings to forecast nonconvectively produced strong wind gusts. Model soundings from the operational Eta and Meso Eta Models were used ...

Abstract: A remarkable case of severe weather occurred near Springfield, Illinois on 6 August 1977. Aerial and ground surveys revealed that 17 cyclonic vortices an anticyclonic vortex, 10 downbursts and 19 microbursts occurred in a ...

Abstract: This article is one in a series of papers from the Symposium on the Mystery of Severe Storms: A Tribute to the Work of T. Theodore Fujita. It reviews Fujita's vast contributions to the understanding of tornadoes and tornadic ...

Abstract: An interesting ice storm of moderate severity occurred along the east slopes of the Appalachians on 13?14 January 1980. Though surface temperatures were initially below freezing in most of this region, objective guidance ...

Abstract: An outstanding issue in the assessment of forecast skill (and value) is whether any advantage that can be obtained through regional knowledge not readily available to distant forecasters supersedes the leveling effect of ...

Abstract: Since late 1995, NCEP has made available to forecasters hourly model guidance at selected sites in the form of vertical profiles of various forecast fields. These profiles provide forecasters with increased temporal ...
