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 .
Weather stations typically have these following instruments: . Thermometer for measuring air and sea surface temperature; Barometer for measuring atmospheric pressure; Hygrometer for measuring humidity
The TWISTEX crew and the vehicles on equipped with mobile mesonets. TWISTEX (a backronym for Tactical Weather-Instrumented Sampling in/near Tornadoes Experiment) was a tornado research experiment that was founded and led by Tim Samaras of Bennett, Colorado, US, that ended in the deaths of three researchers in the 2013 El Reno tornado.
The National Weather Service offers storm spotting training session to the public throughout Central Indiana. Indiana tornado season is approaching. Here's how to help spot severe weather
Skies can sometimes appear green before a tornado because of the scattering of light in a storm. Winds of a tornado may reach 300 miles per hour and damage can stretch several miles.
Storm spotter classes for 2025 are now available for those interested in reporting weather observations to the National Weather Service. Requirements to become a spotter include signing up for an ...
The TOtable TOrnado Observatory (TOTO), developed by NOAA Environmental Research Laboratory scientists, was a 55-gallon barrel outfitted with anemometers, pressure sensors, and humidity sensors, along with devices to record the data. In theory, a team would roll TOTO out of the back of the pickup in the path of a tornado, switch on the ...
Where severe storms are possible, storm spotting groups such as Skywarn in the United States coordinate amateur radio operators and localized spotters to keep track of severe thunderstorms and tornadoes. Reports from spotters and chasers are given to the National Weather Service so that they have ground truth information to warn the general ...
