A true waterspout forms over the water and is not accompanied by a strong storm. If a severe storm with a tornado happens to pass over a stretch of water, the tornado is sometimes called a tornadic waterspout and would be just as dangerous as if it were over land. The difference is entirely in the weather we see with the waterspout.  2, fiche 1, Anglais, - tornadic%20waterspout

Waterspouts form over (or move across) the coastal waters or intracoastal waters ... They are treated as tornadoes over water. There are two type of waterspouts: "fair weather" and "tornadic". Fair weather waterspouts are usually weaker, move slowly, and may not be associated with a thunderstorm. Tornadic waterspouts form within developing thunderstorms, or severe thunderstorms, and move much faster while being more intense.  4, fiche 2, Anglais, - fair%20weather%20waterspout

The most common type of waterspout is a fairweather waterspout, which arises over warm seas, e.g. near Florida. It lasts for only a few minutes. These waterspouts are generally of F0 intensity, with winds of no more than 30 m/s. They typically occur during the developing stage of an airmass thunderstorm, below the main updraft. These thunderstorms are found in weakly sheared environments, so the spin-up must result mainly from vortex stretching and less from vortex tilting.  2, fiche 2, Anglais, - fair%20weather%20waterspout

La trombe marine véritable se forme au-dessus de l'eau et n’ est pas accompagnée d’un violent orage. Si jamais un orage intense produisant une tornade passe au-dessus d’une masse d’eau, cette tornade présente autant de danger que sur terre. La différence entre la tornade et la trombe marine tient exclusivement aux conditions atmosphériques en présence dans le second cas. Si le temps est frais et nuageux et qu'il y a quelques averses mais pas d’orage comme tel, tout entonnoir ressemblant à une tornade qui pourrait se former au-dessus de l'eau est une trombe marine.  1, fiche 2, Français, - trombe%20marine
