No. Waterspouts are generally smaller than most tornadoes. Though a few are in the same size range that tornadoes typically fall into.
Tornadoes are generally more dangerous as they are stronger than waterspouts.
"Water tornadoes," which are called waterspouts, are divided into two categories. Fair-weather waterspouts, are structured differently and generally weaker than classic tornadoes. Tornadic waterspouts are ordinary tornadoes that happen to be on water, they are just as strong as ordinary tornadoes.
Not really. Waterspouts require a much larger body of water to form, such as a lake. However, there are land based cousins of waterspouts called landspouts. In structure they are more like waterspouts than normal tornadoes. It is possible for one to strike a swimming pool, but it would be purely coincidental.
There are no categories for waterspouts specifically. However, waterspouts that hit land are counted as tornadoes. Tornadoes are rated on the Enhanced Fujita scale, which has six levels from EF0 to EF5. Very few waterspouts are stronger than EF1.
No. They are usually slower.
"Rope" and "wedge" are just terms to describe the appearance of a tornado; they are not distinct phenomena. A rope tornado is a tornado that has a very narrow, often winding appearance. Tornadoes often go through a rope stage as they dissipate. A wedge is a very large tornado that appears wider than it is tall. Such large tornadoes are often strong. Waterspouts come in two varieties. Tornadic waterspouts are simply tornadoes that happen to be on water. Fair-weather waterspouts, which are more common, are a product of small-scale convection rather than rotation in a severe thunderstorm. These waterspouts are generally much weaker than ordinary tornadoes but they can still be dangerous to boaters.
No, in fact, they are much less powerful. ----- A waterspout is a tornado that forms over water instead of land. Unless you are on water, in its path, a tornado would be worse, because more people live on land.
Waterspouts
Tornadoes on water are called waterspouts.
On average waterspouts are thinner than tornadoes, though the ranges of size overlap.
Water tornadoes, properly called waterspouts, form best when the water temperature is higher than the air temperature.
