How does a waterspout form?

Answer 1

Scientists believe that tornadoes and waterspouts begin in severe thunderstorms called a supercells and are caused by a vertical wind sheer; a wind that changes direction as it gets higher. This change of direction and height causes the air to begin spinning which results in a tornado or waterspout.

Any intense vortex (AKA funnel clouds) made a touch down on the water body will called waterspout.

There are two types of waterspout:

Non-Tornadic:

This type of waterspout rarely rated higher than F1 in Fujita scales. It usually forms at the bottom of strata-cumulus or developing towering cumulus. It must form over a unstable environment, low vertical windshear area, but strong convergences near the boundary levels (lower level). This is the most common waterspout. This type of waterspout usually associate with vertical convection, rather than rotating updraft.

Tornadic:

As answered above in the previous answer, it's formed by rotating updraft. This kind of Waterspout could be potentially deadly.

Answer 2

A waterspout is an intense columnar vortex (usually appearing as a funnel-shaped cloud) that occurs over a body of water. Most waterspouts form from an ordinary thunderstorm, or even a towering cumulus cloud.

Answer 3

Most waterspouts form from an ordinary thunderstorm, or even a towering cumulus cloud. Both thunderstorms and cumulus clouds generate an updraft. If they occur over a relatively warm body of water the updraft at the surface can be strengthened. If there is any hint of rotation in the air, which can occur on its own, it can get caught up in the updraft, tightened, and intensified to produce a waterspout. This mode of formation is more like that of dust devils than it is of tornadoes.

Answer 4

A water sprout is a tornado over water. Most waterspouts occur when the water is significantly warmer than the air above it. This causes thunderstorms to start developing.

At the same time, convection occurs near the surface as well. If there is localized rotation in the area the surface level convection itself could start rotating. As this convective vortex grows and intensifies it connects to the updraft of a developing storm and strengthens even further.

Answer 5

Waterspouts are very similar to tornadoes, except they're not that powerful, but if it moves on shore, then it's a tornado. Like all tornadoes, they would usually thin out like a big piece of rope, then vanish.

Answer 6

Known officially as tornadoes" by the National Weather Service, they form during the growth stage of convective clouds by the ingestion and tightening of boundary layer vorticity by the tower's updraft. most often occur in drier areas with storms and considerable instability. They generally are smaller and weaker than tornadoes, though many persist in excess of 15 minutes and some have produced F3 damage. They bear an appearance and generative mechanism highly similar to that of waterspouts, usually taking the form of a translucent and highly laminar helical tube. Like waterspouts, they are also technically considered tornadoes since they are defined by an intensely rotating column of air in contact with both the surface and a cloud. Not all are visible, and many are first sighted as debris swirling at the surface before eventually filling in with condensation and dust.

Answer 7

A waterspout forms when a rotating column of air over water connects with a cumulus cloud above. The spinning motion causes water droplets to be lifted into the air, creating a visible funnel-shaped cloud. Waterspouts are typically weaker than tornadoes and usually dissipate once they move onshore.

Answer 8

Waterspouts can occur on most bodies of water in a temperate or tropical climate area. The key factor in waterspout formation is that the water is warmer than the air up above.
