what do mean by waterspout and describe one of its type briefly?
Waterspouts are tornadoes over water. But scientific work over the last 30 or so years has led to a more complicated picture with waterspouts differing in some ways from tornadoes over land, especially large ones. Waterspouts and all the different kinds of tornadoes have a similar basic structure with air moving upward. At the ground or ocean surface, winds are rushing faster and faster as they swirl into the vortex and then upward. Often with both tornadoes and waterspouts, the vortex is seen coming down from the cloud, but not obviously touching the ground or ocean. Such vortices that don’t seem to touch the ground are called “funnels” or “funnel clouds.” It’s important to say “seems” not to touch because often, especially in the beginning, the vortex is invisible along part of its path. We begin to see the vortex when its lower air pressure cools the air enough to condense water vapor in the air into tiny water droplets. Beginning in the late 1960s when he investigated waterspouts i
