Abstract: n situ data collected within a weakly tornadic, high-precipitation supercell occurring on 23 May 2007 near Perryton, Texas, are presented. Data were collected using a recently developed fleet of 22 durable, rapidly deployable ...

Abstract: nique observations of the interaction and likely merger of two cyclonic tornadoes are documented. One of the tornadoes involved in the interaction was the enhanced Fujita scale (EF5) El Reno?Piedmont, Oklahoma, tornado ...

Abstract: he forcing and origins of an internal rear-flank downdraft (RFD) momentum surge observed by the second Verification of the Origin of Rotation in Tornadoes Experiment (VORTEX2) within a supercell occurring near Dumas, Texas, ...

Abstract: The Storm Prediction Center (SPC) tornado database, generated from NCEI?s Storm Data publication, is indispensable for assessing U.S. tornado risk and investigating tornado?climate connections. Maximizing the value of this ...

Abstract: wo spatial verification methods are applied to ensemble forecasts of low-level rotation in supercells: a four-dimensional, object-based matching algorithm and the displacement and amplitude score (DAS) based on optical ...
