An impressive supercell formed yesterday in the southwestern state of Kansas. that left very heavy rains, large hail and even a tornado. Several groups of storm chasers gathered there, knowing that the great plains, with certain conditions of atmospheric instability, are capable of generating colossal cumulonimbus clouds. His photos and videos today have gone around the world.
One of those storm clouds circled the sky, starting from a lenticular base that levitated over the cereal fields. This cloud structure is known in the meteorological field as mesocyclone and assumes the presence of a supercell. These cumulonimbus clouds they can exceed 15 kilometers in height and reach a width of up to 50 kilometers, and even more.
In Kansas and Texas stormy phenomena left hail the size of a chicken egg. Local forecasting services agreed to warn hours before this possibility, including WeatherNation meteorologists from Colorado: “If you are in the path of these storms, move your vehicles or goods to a safe place.”
The storm chasers ignored it and made their way to Ulysses, a Grant County town. In that corner FThey witnessed the huge mesocyclone with several overlapping dishes (shelf cloud) that hinted at a strong updraft.
Under this cloud it does not usually rain, that is why its limits are so well defined, although it does the dreaded tornadoes may await. Precipitation falls in the most uniform and leaden sky area. Together they create images that are engraved on the retina.
