See media help. A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning [1] and its acoustic effect on the Earth's atmosphere, known as thunder. [2] Relatively weak thunderstorms are sometimes called thundershowers. [3]
A tornado is a violently rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It is often referred to as a twister, whirlwind or cyclone, [ 1 ] although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the ...
A tornado is a dangerous rotating column of air in contact with both the surface of the earth and the base of a cumulonimbus cloud (thundercloud), or a cumulus cloud in rare cases. Tornadoes come in many sizes but typically form a visible condensation funnel whose narrowest end reaches the earth and is surrounded by a cloud of debris and dust.
Tornadogenesis is the process by which a tornado forms. There are many types of tornadoes, varying in methods of formation. Despite ongoing scientific study and high-profile research projects such as VORTEX, tornadogenesis is a volatile process and the intricacies of many of the mechanisms of tornado formation are still poorly understood. [1][2 ...
A mesocyclone is a meso-gamma mesoscale (or storm scale) region of rotation (vortex), typically around 2 to 6 mi (3.2 to 9.7 km) in diameter, most often noticed on radar within thunderstorms. In the northern hemisphere it is usually located in the right rear flank (back edge with respect to direction of movement) of a supercell, or often on the ...
The team needed to make one last maneuver to ensure a successful intercept: getting to the south of the tornado to be right in its path. The team executed the maneuver just in time. "I was ...
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 ...
“The most robust increases in these tornado-producing environments seem most likely to happen in what used to be cooler times of the year,” Swain said. “In winter, historically, you didn’t ...
