2 days ago · tornado, a small-diameter column of violently rotating air developed within a convective cloud and in contact with the ground. Tornadoes occur most often in association with thunderstorms during the spring and summer in the mid-latitudes of both the Northern and Southern Hemispheres.
Aug 28, 2019 · A tornado is a violently rotating column of air that extends from a thunderstorm to the ground. It's often portended by a dark, greenish sky. Black storm clouds gather. Baseball-size hail may...
A tornado is a violently rotating column of air, in contact with the ground, either pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud. [20] For a vortex to be classified as a tornado, it must be in contact with both the ground and the cloud base.
The peak “tornado season” for the southern Plains (e.g., Texas, Oklahoma, and Kansas) is from May into early June. On the Gulf coast, it is earlier in the spring. In the northern Plains and upper Midwest (North and South Dakota, Nebraska, Iowa, Minnesota), tornado season is in June or July.
4 days ago · All these conditions can result in rolling, spinning air currents inside the cloud. Although this spinning column of air starts out horizontal, it can easily go vertical and drop down out of the cloud. When it touches the ground, it's a tornado . . . and a big problem to anything in its path.
May 21, 2019 · How tornadoes form and how they die is not fully understood, yet scientists probing those mysteries—and aiming to improve warning systems—have pinpointed key risk factors. A tornado, or ...
When the warm and cool airstreams meet, tornadoes are likely to form. Though the storms can happen at any time of the year, tornado season in Texas, Oklahoma, and Kansas occurs in May through...
A tornado can form in a thunderstorm where the rotating air of an updraft (shown in purple) meets the rotating air of a downdraft (shown in aqua), which has turned upward. Tornadoes only form when a thunderstorm has a particular combination of winds.
Understanding these winds—the tornado's strongest and most erratic—may enable engineers to design better tornado-resistant structures. A probe captures the first ever video images inside a...
