What causes a whirlwind?
A vortex is a rotating motion around a center. A vortex can be caused by the winds surrounding hurricanes or tornadoes. They can also form from the wake of boats and liquid and gases in stirred fluids.
Does every tornado have a vortex?
Every tornado is a vortex.
What forms a vortex?
A vortex is form when the whirling motion of the cloud vortex results from a rapid downdraft of cold air replacing rising hot air.
What is a vortex of a water tornado?
A vortex generator is an aerodynamic surface, consisting of a small vane that creates a vortex. Some surfaces on an airplane can result in air flow separating from the surface or skin. A vortex generator creates a tip vortex which draws energetic, rapidly-moving air from outside the slow-moving boundary layer into contact with the aircraft skin. This keeps the flow close to the aircraft surfaces. Vortex generators delay flow separation and aerodynamic stalling; they improve the effectiveness of control surfaces. You may see vortex generators as a row of small vanes that are mounted in a row along a tail surface.
How is a hurricane similar to a vortex?
A hurricane is a kind of vortex. A vortex can be defined as a spiral motion of fluid (liquid or gas) withing a limited area, especially such as motion that pulls in things near it. A hurricane meets this definition.

How do you use vortex in a sentence?
A vortex is a whirling, spiralling mass, whether liquid, gas or flames. Example of sentences would be:When you swirl your hand around and around in water, it creates a vortex.Within the huge tornado was a vortex of dust and debris.

What current brings air from the arctic circle southward?
The polar jet streams are circulating air currents around the poles. In the Northern Hemisphere, the jet stream carries air eastward, and can transport Arctic air southward from the north polar vortex into the lower latitudes.
What causes a whirlwind?
A vortex is a rotating motion around a center. A vortex can be caused by the winds surrounding hurricanes or tornadoes. They can also form from the wake of boats and liquid and gases in stirred fluids.
What is the difference between a multiple vortex tornado and a single vortex tornado?
A multiple vortex tornado has smaller, short-lived vortices moving around inside of it. The suction vortices have stronger winds than the rest of the tornado and are noted for cutting narrow curved swaths of intense damage. A multiple vortex tornado sometimes has the appearance of two or more tornadoes moving circles. A single vortex tornado is simply one vortex of tornadic wind.
Is vortex an adjective?
No. Vortex is a noun.
What is an antonym for vortex?
There is no antonym for vortex.
