Abstract: The TOTO (Totable Tornado Observatory) device was field tested in the Southern Plains by a severe-storm intercept team from the University of Oklahoma from late May through early June 1981. The results from two intercept ...

Abstract: Faculty and students from the School of Meteorology at the University of Oklahoma and staff members from the Atmospheric Technology Division at the National Center for Atmospheric Research (NCAR) participated in a special ...

Abstract: Photographic evidence is presented of funnel clouds pendant from the bases of convective clouds whose updrafts appear to be rooted well above the boundary layer. These funnel clouds occur in environments supportive of ...

Abstract: This brief case study describes the unusually benign environment in which a funnel cloud formed along a line of convective towers during the summer in Kansas. The parent cloud line was solitary and very narrow, yet organized ...

Abstract: Photographic and mobile-radar documentation of the dissipation of a supercell and a severe convective storm that had not yet developed into a mature supercell are discussed. It is hypothesized, based on these cases and on ...

Abstract: The characteristics and environment of low-precipitation severe thunderstorms in the Southern Plains have been summarized by Bluestein and Parks in 1983. Photographic documentation is given here of several storms not ...

Abstract: Tornadoes are often reported as tropical cyclones make landfall. In this note I present photographic evidence of a possible funnel cloud in the eye of Hurricane Norbert in the Eastern Pacific, far from landfall.

Abstract: Photographs are presented that illustrate the various forms in which ?flanking lines? exist in nature. Flanking lines may appear not only as the commonly observed sloping line of cumulus congestus, but also as erect towers ...

Abstract: The rare occurrence of a tornado in the Sierra-Nevada region of California is documented. The synoptic-scale wind and pressure field and the thermodynamic structure of the environment are discussed.

Abstract: Photographs of several severe storm related phenomena are described. A double wall cloud having a double vortex structure evolved from a single wall cloud, and subsequently turned back into a single wall cloud and produced ...
