That would be a tornado. But there is no evidence that speeds get close to 400 mph.
The highest known winds in a tornado were just over 300 mph.
A tornado is a violently rotating column of air that extends from a thunderstorm to the ground. It is capable of causing significant damage due to its high winds and can result in destruction of buildings and vegetation in its path. Tornadoes are commonly observed during severe thunderstorms.
They are called tornadoes. Tornadoes are violent rotating columns of air that extend from a thunderstorm to the ground.
A tornado is a violently rotating an often destructive column of air extending from the base of a thunderstorm to the ground. They are often made visible by a condensation funnel and a cloud of dust and/or debris. A supercell is a type of very powerful, rotating thunderstorm typically defined by a rotating updraft called a mesocyclone. They are the strongest thunderstorms on earth. The majority of tornadoes are produced by the mesocyclone of a supercell.

Tornadoes on water are called waterspouts.
A tornado is a violently rotating columns of air in contact with the base of a thunderstorm and the ground. Tornadoes are usually produced by a type of strong thunderstorm called a supercell.

The tornado itself is a spinning column of rising air. They usually form froma large rotating column of air called a mesocyclone.
The columns are called groups (or, sometimes, families). The rows are called periods.
periods are the rows and families are the columns
Tornadoes are called "twisters." Hurricanes are sometimes called "tropical storms" before they reach violent wind speeds, and are referred to as "typhoons" in the Pacific. Both tornadoes and hurricanes can be called "cyclones" because they both have violently rotating wind.
A tornado is a violently rotating column of air extending from the base of a thunderstorm to the ground, often made visible by a funnel or cone shaped cloud. A tornado occurs when rolling air called wind shear is turned vertical by a thunderstorm. This creates a supercell, a storm with a strong, rotating updraft called a mesocyclone. Under the right conditions a downdraft can wrap around the mesocyclone, forcing the rotating into a tighter, more intense vortex: a tornado.
The columns are known as groups.
