When the conditions are perfectly matched, disasters will sweep the Great Plains: a supercell storm, with its vast, Anvil-like formations in its optimal, Can release hail, lightning and tornadoes.
Although storms are relatively rare, they can last for hours; a supercell thrives in warm air moving upwards and cold air moving downwards, and when the two air streams travel in different paths, The latter avoids inhibiting the former. Although only about 20% of supercells produce tornadoes, they Majority Tornadoes tearing through America every year.
In short, the supercell on the horizon is an ominous sign. But what makes storms deadly and how often they occur, meteorologists are not sure.This is why researchers Spent decades Fly into and drive through extreme storms and evaluate the conditions required for supercells to create dangerous conditions, especially tornadoes.
It is hoped that by better understanding when the tornado will land, officials can issue a warning to the public earlier Increase locals’ trust in severity The danger is coming.
A supercell near West Point, Nebraska. In order to better understand when a storm produces a tornado, Researchers fly Drone 2,500 feet above the ground, into supercells in Nebraska, South Dakota, Kansas, and several other states.
A tornado supercell storm moving over the Great Plains during sunset.Historically, tornadoes have had the greatest impact on the Great Plains, but more and more evidence shows that extreme weather events are Eastward more and more frequently, picture Mississippi, Alabama and Tennessee.
A high precipitation supercell passing through the dunes of Nebraska.Supercells usually produce the largest and fastest falling hail; the ice ball in the strongest storm may be Two to four inches wide, Crashing at a speed of 44 to 75 miles per hour.
Tornado funnel and debris cloud under a supercell in McCook, Nebraska.The black cylinder around the bottom of the tornado is a cloud of debris, a vortex of churning mud and debris that can expand to Twice the width of the twister itself.
A supercell moving over the Great Plains.Brewing in the storm is a draft Using the correct rotation, size, depth, and duration, the Doppler radar marks it as Medium cyclone: The precursor of a tornado.
A slow-moving tornado supercell accelerates near Bartlett, Nebraska.A slower thunderstorm traverses the landscape at a speed of 12 miles per hour, and The fastest super battery can reach 40 to 50 miles per hour.
At sunset in Bledsoe, Texas, a supercell sprung up like mushrooms.National research on thunderstorms began Thunderstorm Project [1945Weathereventsareseenasathreattoflight-sonaturallytheprojectallowstheaircrafttopassdirectlythroughstormclouds[1945年。天氣事件被視為對飛行的威脅——所以很自然地，該項目讓飛機直接穿過暴風雲。
The supercell and tornado that swept Lamar, Colorado.The National Weather Service rated the tornado intensity as Post-damage investigation. New research shows that for tornadoes generated by supercells, traditional evaluation methods May underestimate wind speed.
A supercell warned by a tornado is heading towards Enid, Oklahoma. Someone must witness the tornado to be recorded.As the population density has been increasing since the early 1900s It’s not clear if the weather is more common or if there are more people watching around.
