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 ...
Joshua Wurman participated in both the VORTEX projects, doing early deployments of the first scraped together DOW radars for VORTEX1 and served on the steering committee and was a principal investigator (PI) for VORTEX2, the field research phase of which occurred from 2009-2010. [1]
A satellite tornado is a tornado that revolves around a larger, primary tornado and interacts with the same mesocyclone. Satellite tornadoes occur apart from the primary tornado and are not considered subvortices; the primary tornado and satellite tornadoes are considered to be separate tornadoes. The cause of satellite tornadoes is not known.
Weather satellite. A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting (covering the entire Earth asynchronously), or geostationary (hovering over the same spot on the equator).
NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the ...
A meso-beta scale vortex. Mesoscale meteorology is the study of weather systems and processes at scales smaller than synoptic-scale systems but larger than microscale and storm-scale. Horizontal dimensions generally range from around 5 kilometres (3 mi) to several hundred kilometres. Examples of mesoscale weather systems are sea breezes, squall ...
The polar vortex is a gigantic, circular area of cold air high up in the atmosphere that typically spins over the North Pole (as its name suggests). What is the polar vortex? In-depth look at how ...
