Waterspouts — Formation, Types & Difference from Tornadoes


What is a Waterspout?

A waterspout is a rotating column of air associated with a water body, often appearing as a funnel containing water spray/mist.

Types

1. Fair-weather waterspout

  • Usually develops over relatively calm/open water.

  • Often associated with developing cumulus clouds.

  • Generally weaker.

  • Develops from the water surface upward.

2. Tornadic waterspout

  • Essentially a tornado occurring over water.

  • Associated with thunderstorms.

  • Can produce strong winds, hail and lightning.

  • Can move from land to water.

Prelims Pointers

  • Waterspout ≠ necessarily a conventional tornado.

  • Common over warm tropical/subtropical waters.

  • Tornadic waterspouts are generally more destructive.

  • If a waterspout moves ashore, it can cause tornado-like damage.
