What is a sideways tornado called?
This harmless phenomenon, called a roll cloud, forms where cold air drives low-hanging, moist warm air upward. Cooler temperatures condense the moisture to form clouds.Can tornadoes be horizontal?
Horizontal vortices are extemely rare violently rotating tubes that appear to get horizontally pulled into the tornado. The are like small horizontal tornadoes getting sucked into that large parent tornado.What is the difference between a derecho and a tornado?
A derecho can be as destructive as a tornado, but it is destructive in a decidedly different way. The strong, swirling winds of a tornado will cause debris to fall every which way, while a derecho's straight-line winds are similar to a regular thunderstorm—but stronger.How rare is a derecho storm?
Derechos are a relatively rare event, as they only tend to occur from once a year to once every four years across portions of the eastern two-thirds of the U.S., according to the National Weather Service. “People should take these storms seriously,” Weather Service meteorologist Brian Barjenbruch said.Do tornadoes start sideways?
The Short Answer:Although the spinning currents start out horizontal, they can turn vertical and drop down from the cloud--becoming a tornado.

What is a super tornado?
A severe, usually isolated thunderstorm characterized by a strong rotating updraft and often giving rise to damaging winds, electrical storms, flooding, large hail, and tornadoes.When was the last derecho in the United States?

The Short Answer:Derechos are fast-moving bands of thunderstorms with destructive winds. The winds can be as strong as those found in hurricanes or even tornadoes! Unlike hurricanes and tornadoes, these winds follow straight lines.
What happens during a derecho?
Derechos are associated with bands of rapidly moving showers or thunderstorms variously known as bow echoes, squall lines, or quasi-linear convective systems. Although a derecho can produce destruction similar to that of a tornado, the damage typically occurs in one direction along a relatively straight path.Why did the derecho happen?
They can reach over 100 mph and are caused by air being dragged down by precipitation. When the air reaches the ground, it spreads outward across the surface of the land it encounters in a straight line. A Derecho is a very long lived and damaging thunderstorm.Is a derecho a microburst?
A typical derecho consists of numerous microbursts, downbursts, and downburst clusters. By definition, if the wind damage swath extends more than 240 miles (about 400 kilometers) and includes wind gusts of at least 58 mph (93 km/h) or greater along most of its length, then the event may be classified as a derecho.What is a wedge tornado?
"Wedge" is informal storm observers' slang for a tornado which looks wider than the distance from ground to ambient cloud base.What is a rotating storm?
A supercell is a thunderstorm characterized by the presence of a mesocyclone: a deep, persistently rotating updraft. For this reason, these storms are sometimes referred to as rotating thunderstorms.Are Landspouts tornadoes?
A landspout is a tornado with a narrow, rope-like condensation funnel that forms while the thunderstorm cloud is still growing and there is no rotating updraft - the spinning motion originates near the ground. Waterspouts are similar to landspouts, except they occur over water.Is a derecho a hurricane?
derecho, also called land hurricane, windstorm traveling in a straight line characterized by gusts in excess of 93 km (58 miles) per hour and the production of a swath of wind-generated damage along a front spanning more than 400 km (250 miles) in length.Was Kentucky storm a derecho?
The storm system hit the north-central US on 15 December, separately from the record, killer tornadoes that devastated a swath of states but caused most damage in Kentucky on the night of 10 December. A derecho storm has no “eye” and its powerful winds cause damage in a relatively straight line.What states do derechos occur?
The highest annual frequencies of occurrence appear along the "Corn Belt," from Minnesota and Iowa into western Pennsylvania, and in the south central states, from eastern parts of the southern Plains into the lower Mississippi Valley.Is derecho a new term?
While the term was used in the meteorological community for a short time during the late nineteenth century, it disappeared from use for nearly 100 years until resurrected by severe weather meteorologists in the mid-1980s.How often do derechos happen?
The occurrence of derechos is divided into two seasons; the "warm" season which is May, June, July and August. 70% of all derechos occur during these four months.

Answer and Explanation: A mini-tornado usually refers to a dust devil. This is a small column of rotating air that forms due to temperature changes with rapidly heating air above sun-warmed earth or pavement. They can form on clear days and usually only travel a short distance before dissipating.What is a mothership supercell?
Mothership supercells have an extreme, rotating upward draft, which can produce hail, flash floods and even tornadoes. A giant storm system captured on video over Montana looks like a giant spaceship descending on earth. But it's actually a unique type of severe storm system called a mothership supercell.
