Convective storm detection is the meteorological observation, and short-term prediction, of deep moist convection (DMC). DMC describes atmospheric conditions producing single or clusters of large vertical extension clouds ranging from cumulus congestus to cumulonimbus , the latter producing thunderstorms associated with lightning and thunder .
[1] [2] A TDS may also be indicated by dual-polarization radar products, designated as a polarimetric tornado debris signature (PTDS). Polarimetric radar can discern meteorological and nonmeteorological hydrometeors and the co-location of a PTDS with the enhanced reflectivity of a debris ball are used by meteorologists as confirmation that a ...
Strong mesocyclone on a thunderstorm near Tuscaloosa, Alabama, that was analyzed as fitting the characteristics of a TVS.It was associated with 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.

Mini-tornado – A fallacious term often used in European news media to refer to tornadoes occurring there; even large, strong, and/or long track tornadoes produced by supercells. This is apparently due to the erroneous perception that "real" tornadoes do not occur in Europe (or elsewhere where the term is applied).
WoF Tornado Threat Prediction (WoF-TTP) is a research project to develop a 0–1 hour, 1-km resolution suite of high detail computer models to forecast individual convective storms and their tornadic potential. Target future average lead-time for tornado warnings via WoF-TTP is 40–60 minutes.
Some of the most notorious twisters in U.S. history were wedge tornadoes, including the EF5 that leveled Joplin, Missouri, on May 22, 2011, and the El Reno tornado, which was a jaw-dropping 2.6 ...
The tornado was among at least 1,735 tornadoes that occurred across the country in 2024, according to SPC data. The total is more than 40% higher than the typical number of tornadoes seen in an ...
Experts say 2024’s tornado outbreaks set it apart, even in a year full of extreme weather. The U.S. recorded the highest number of tornadoes in a decade.
