have a large vertical and horizontal extent which are often said to look

Waterspout off the southeast coast of Australia
So, what excatly is a waterspout? Waterspouts are intense vortex funnels, which can sometimes be destructive, with a small width, that occur over water. Like dust devils and tornadoes, waterspouts are convective vortices whose circulations are driven by convection forming rising shafts of air. Proper waterspouts form over the water and will dissipate almost immediately upon touching any landmass. You can also get Tornadic waterspouts which are tornadoes which have been produced by severe thunderstorms and touch down onto or cross a body of water.
