Although each tornado is unique, most kinds of tornadoes go through a life cycle of formation, maturation, and dissipation. [4] The process by which a tornado dissipates or decays, occasionally conjured as tornadolysis, is of particular interest for study as is tornadogenesis, longevity, and intensity.
Reliably predicting tornado intensity and longevity remains a problem, as do details affecting characteristics of a tornado during its life cycle and tornadolysis. Other rich areas of research are tornadoes associated with mesovortices within linear thunderstorm structures and within tropical cyclones. [138]
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 ...
An EF4 tornado with wind speeds ranging from 166 to 200 mph can cause devastating damage. Most to all walls on a well-built house will likely collapse, and high-rise buildings can sustain ...
Tornadoes exist on the microscale or low end of the mesoscale gamma domain. The cycle begins when a strong thunderstorm develops a rotating mesocyclone a few miles up in the atmosphere, becoming a supercell. As rainfall in the storm increases, it drags with it an area of quickly descending air known as the rear flank downdraft (RFD). This ...
Tornado climatology. Areas worldwide with the highest frequency of tornadoes are indicated by orange shading. Tornadoes have been recorded on all continents except Antarctica. They are most common in the middle latitudes where conditions are often favorable for convective storm development. The United States has the most tornadoes of any ...
The tornado became the subject of several scientific papers analyzing the life cycle of and wind speed speeds in a tornado. Among the studies was the first-ever photogrammetric analysis of wind speeds in a tornado. The film of the tornado is still regarded as being of exceptionally high quality and sharpness.
This radar was used to scan and film the complete life cycle of a tornado in 1973. By comparing the film with velocity images from the radar, the researchers found a pattern that showed the tornado beginning to form before it could be visually detected on the film. The researchers named this phenomenon the Tornado Vortex Signature (TVS). [3]
