In particular, two elements are needed: an upward trend (the showers) and winds from different directions. (…) It remains very impressive to watch. ”
A waterspout is a rotating column of air mixed with water, forming a cloudy funnel, under a convective cloud above a body of water. These micro-scale phenomena are formed when conditions are very unstable as cold air passes over warm water. Usually less intense than a tornado, they dissipate once on land.
