Whirlpools are most commonly associated with tornadoes, but can also occur in other types of storms, such as hurricanes and waterspouts. They are formed when the air currents within the storm become unstable and begin to rotate, creating a vortex. This vortex can then draw in more air and debris, causing it to grow in size and strength.
Whirlpools can cause significant damage to property and infrastructure, and can also be deadly. If you see a whirlpool, it is important to take shelter immediately and stay away from the area until the storm has passed.
Here are the steps on how whirlpools occur:
1. Thunderstorm formation: A thunderstorm cloud forms when warm, moist air rises from the ground and meets cooler, drier air at higher altitudes. The rising air cools and condenses, releasing energy that causes the cloud to grow and develop.
2. Updraft: As the thunderstorm cloud grows, it creates an updraft of warm air. This updraft can be very strong, and can reach speeds of up to 100 miles per hour.
3. Rotation: The updraft of air within the thunderstorm cloud can cause the cloud to begin to rotate. This rotation can be caused by a number of factors, such as the wind shear between the rising and sinking air, or the Earth's rotation.
4. Whirlpool formation: As the cloud continues to rotate, a whirlpool can form. A whirlpool is a column of rotating air that extends from the base of the cloud to the ground. Whirlpools can be very destructive, and can lift objects and people into the air.
5. Dissipation: Whirlpools typically dissipate when the thunderstorm cloud loses its energy. This can happen when the updraft of air weakens, or when the cloud encounters a change in wind direction.
