VORTEX projects. NSSL mobile mesonet vehicles of the first Project VORTEX, equipped with surface measurement equipment. The V erification of the O rigins of R otation in T ornadoes Ex periment (or VORTEX) are field experiments that study tornadoes. VORTEX1 was the first time scientists completely researched the entire evolution of a tornado ...
A tornadic vortex signature, abbreviated TVS, is a Pulse-Doppler radar weather radar detected rotation algorithm that indicates the likely presence of a strong mesocyclone that is in some stage of tornadogenesis. [1] It may give meteorologists the ability to pinpoint and track the location of tornadic rotation within a larger storm, and is one ...
Part of the Tornado outbreak sequence of May 19–27, 2024 and Tornadoes of 2024. On the afternoon of May 21, 2024, a violent and destructive multi-vortex tornado struck the communities of Villisca, Nodaway, Brooks, Corning, and Greenfield in southwestern Iowa, killing five people and injuring 35 others. The tornado was the strongest of a large ...
A recent study by researchers at NOAA’s National Severe Storms Laboratory using Doppler Radar scans suggests the current methods of measuring tornadoes may be underestimating the twister's true ...
More than a dozen tornadoes touched down in the state that day. While most everyone in the area hunkered in basements, a team of nine scientists — storm chasers — sought to get as close as ...
April 26, 1991. Ceres, Oklahoma. 268 mph (431 km/h) 280 mph (450 km/h) 280 mph (450 km/h) A University of Oklahoma chase team headed by Howard Bluestein utilized mobile doppler weather radar to analyze the tornado. The radar measured peak winds of 120–125 m/s (270–280 mph; 430–450 km/h) between 150–190 m (490–620 ft) above the surface ...
Nevertheless, the El Reno tornado is one of the two strongest tornadoes ever recorded in terms of maximum wind speeds, the other being the 1999 Bridge Creek–Moore tornado which doppler radar measured 321 miles per hour (517 km/h) mph, later revised to 301±20 mph. The 1997 Jarrell tornado was a multiple vortex tornado. The infamous “Dead ...
The tornado warning issued for DuPage, Cook, and Will counties. The Storm Prediction Center had issued an Enhanced (3/5) risk for severe weather over extreme eastern Iowa, northern Illinois and Indiana, southern Michigan, and extreme northwest Ohio for the potential of severe weather, focused on damaging straight-line winds, with the potential for isolated large hail and non-significant tornadoes.
