Abstract: An F5 tornado that devastated Plainfield, Illinois, and environs on 28 August 1990, killing 29 people, is shown to be preduced by a thunderstorm characterized by highly anomalous could-to-ground (CG) lightning activity. ...

Abstract: A remarkable long-lived, large-amplitude gravity wave in the Carolinas and Virginia on 27 February 1984 is investigated by means of a subsynoptic-scale case study. The wave was characterized by a minor-wave of elevation ...

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: he 31 May 2013 El Reno, Oklahoma, tornado is used to demonstrate how a video imagery database crowdsourced from storm chasers can be time-corrected and georeferenced to inform severe storm research. The tornado?s exceptional ...

Abstract: The process of tornadogenesis in complex terrain environments has received relatively little research attention to date. Here, an analysis is presented of a long-lived supercell that became tornadic over complex terrain ...

Abstract: AbstractRapid-scan radar observations of a supercell that produced near-record size hail in Oklahoma are examined. Data from the National Weather Radar Testbed Phased Array Radar (PAR) in Norman, Oklahoma, are used to study ...

Abstract: AbstractThe tropical Andes of southern Peru and northern Bolivia have several major mountain summits suitable for ice core paleoclimatic investigations. However, incomplete understanding of the controls on the isotopic ...

Abstract: AbstractThis study used the first detailed radar measurements of the vertical structure of precipitation obtained in the central Andes of southern Peru and Bolivia to investigate the diurnal cycle and vertical structure ...
