Waterspout - In general, a tornado occurring over water. Specifically, it normally refers to a small, relatively weak rotating column of air over water beneath a Cb or towering cumulus cloud.
Waterspout - a funnel-shaped or tubular column of rotating cloud-filled wind usually extending from the underside of a cumulus or cumulonimbus cloud down to the surface of an ocean or lake ...
WATERSPOUT: A column of rotating air over a body of water (ie. a tornado over the water).
Waterspout- a column of rapidly spiraling air that develops over warm, usually shallow, water in seas or large lakes.
WATERSPOUT - A violently rotating column of air usually forming a pendant from a cumulus/cumulonimbus cloud, occurring over a body of water, and having circulation reaching the water.
waterspout—See tornado.
water vapor—Water in the invisible gaseous form.
Waterspout- A rapidly rotating column of air extending from a cumulonimbus cloud with a circulation that reaches the surface of the water, (i.e. a tornado over water).
Waterspout: Phenomenon similar to the tornado that occurs over the sea.
Weakening: In synoptic meteorology, the weakening of a high- pressure center means a decrease in its central pressure in time.
Waterspout- A tornado-like formation over water, usually much smaller and less vigorous than a true tornado.
Waterspout
A small whirling storm over water which can either be spawned from the base of a thunderstorm, or formed in a cold outbreak of Arctic air. They are similar, but generally no as severe as tornadoes.

Waterspout - A tornado occurring over water.
Weather - It describes the condition of the air at a particular time and place. Weather also tells how the air moves (wind) and describes anything it might be carrying such as rain, snow or clouds.
WATERSPOUT - A vortex of tornado structure and velocities over water. The rotation must reach the water surface to classify as a waterspout.
See: waterspouts
Dust devils are small vortexes that form near the ground. Larger vortexes not associated with a thunderstorm are sometimes called landspouts.

What are Waterspouts?
Is a water spout a tornado? Learning how tornadoes form could save your life. Would you know what to look for? Find out everything you need to know about the formation of these violent twisters.
issued for potentially hazardous weather conditions usually of short duration (up to 2 hours) producing sustained marine thunderstorm winds or associated gusts of 34 knots or greater; and/or hail 3/4 inch or more in diameter; and/or waterspouts ...
WATERSPOUT A small, weak tornado, which is not formed by a storm-scale rotation. It is generally weaker than a supercell tornado and is not associated with a wall cloud or mesocyclone.
The exact definition of waterspout is debatable. In most cases the term is reserved for small vortices over water that are not associated with storm-scale rotation (i.e., they are the water-based equivalent of landspouts).
Tornado: Waterspout: Tornado are over water. 20. Tornado: A funnel cloud which touches the ground. 21. Tornadic Activity: When a Tornado/Funnel Cloud or Waterspout may occur or has been sighted. ...
Note particularly the development of the cloud/s giving rise to the thunderstorm/tornado/waterspout/etc. What we are looking for is the rapidity of build of the cloud; its vertical extent in a noted time.
This is issued by the National Weather Service for hazardous weather conditions (thunderstorms over water, thunderstorms that will move over water, cold air funnels over water, or waterspouts) usually of short duration (2 hours or less) and producing ...
In general use the term cyclone is applied to any storm, especially violent, small-scale circulations such as tornados, waterspouts, and dust devils.
England has the most tornadoes in Europe, about 50 per year, including waterspouts, mostly in the south and east. These are mainly F0 and F1, with only a few F3's reported, and no F4's or F5's. The Netherlands is second with 35 per year.
Listed weather types include tornado, waterspout, funnel cloud, thunderstorm and severe storm, liquid precipitation (drizzle, rain, rain showers), freezing precipitation (freezing drizzle, freezing rain), and frozen precipitation (snow, snow pellets, ...
Funnel clouds have no detectable debris or damage at ground level. The same is true for waterspouts. If there is a dark spot appearing on the sea surface underneath a condensation funnel, than it is a waterspout. If not, it's a funnel cloud.
Landspouts typically are observed beneath Cbs or towering cumulus clouds (often as no more than a dust whirl), and essentially are the land-based equivalents of waterspouts.

Funnel Cloud
Cloud formed at the core of a waterspout or tornado vortex, sometimes extended right down to the ground, caused by the reduction of pressure at the center of the vortex.
Gale
Wind with a speed between 34 and 40 knots.
Special Marine Warning (SMW) This is issued by the National Weather Service for hazardous weather conditions (thunderstorms over water, thunderstorms that will move over water, cold air funnels over water, or waterspouts) usually of short ...
SNOW DEVIL
A small, rotating wind that picks up loose snow instead of dirt (like a dust devil) or water (like a waterspout). Formed mechanically by the convergence of local air currents. May be called a snowspout.
It is generally weaker than a supercell tornado and is not associated with a wall cloud or mesocyclone. It may be observed beneath cumulonimbus or towering cumulus clouds and is the land equivalent of a waterspout.
is not associated with a wall cloud (visually) or a mesocyclone (on radar). Landspouts typically are observed beneath Cb's or towering cumulus clouds (often as no more than a dust whirl), and essentially are the land-based equivalents of waterspouts.
winds in the funnel can reach 300 mph, the strongest winds on Earth. Funnels usually travel at 20 to 40 mph, moving toward the northeast. When tornadoes form over lakes or oceans they suck water into the funnel cloud and are called waterspouts.
In the central plains of the United States they are most frequent in spring during the late afternoon. See also supercell tornado, nonsupercell tornado, gustnado, landspout, waterspout. 2.
This is usually associated with severe thunderstorms or waterspouts.SprayAn ensemble of water droplets torn by the wind from an extensive body of water, generally from the crests of waves, ...
