6 How often do tornadoes occur in the United Kingdom?
On average, 33 tornadoes are reported each year in the United Kingdom. This average is based on a 30 year period, though in reality the actual yearly figures may vary dramatically from year to year.
8 How does this compare with other nations?
In order to accurately compare tornado frequencies between different countries, land area must be taken into account - after all, a large nation will report many tornadoes simply because of its large land area. When land areas are taken into account, the United Kingdom actually has the highest frequency of reported tornadoes per unit area in the world. This was first recognised by an American meteorologist, Dr. T. Fujita, in 1973.

NON-TORNADIC WATERSPOUTS
Waterspouts that are not associated with a rotating updraft of a supercell thunderstorm are known as "non-tornadic" or "fair-weather waterspouts", and are by far the most common type. Fair-weather waterspouts occur in coastal waters and are associated with dark, flat-bottomed, developing convective cumulus towers. Waterspouts of this type rapidly develop and dissipate, having life cycles shorter than 20 minutes.[7] They usually rate no higher than EF0 on the Enhanced Fujita scale, generally exhibiting winds of less than 30 m/s (67 mph).[8] They are most frequently seen in tropical and sub-tropical climates, with upwards of 400 per year observed in the Florida Keys.[9] They typically move slowly, if at all, since the cloud they are attached to is horizontally static, being formed by vertical convective action instead of the subduction/adduction interaction between colliding fronts.[9][10] Fair-weather waterspouts are very similar in both appearance and mechanics to landspouts, and largely behave as such if they move ashore.[9]
TORNADIC
"Tornadic waterspouts", also accurately referred to as "tornadoes over water", are formed from mesocyclonic action in a manner essentially identical to traditional land-based tornadoes in connection with severe thunderstorms, but simply occurring over water.[11] A tornado which travels from land to a body of water would also be considered a tornadic waterspout.[12] Since the vast majority of mesocyclonic thunderstorms occur in land-locked areas of the United States, true tornadic waterspouts are correspondingly rarer than their fair-weather counterparts in that country. However, in some areas, such as the Adriatic, Aegean and Ionian seas, tornadic waterspouts can make up half of the total number.[13]
SNOWSPOUT
A winter waterspout, also known as a snow devil, an icespout, an ice devil, a snonado, or a snowspout, is an extremely rare instance of a waterspout forming under the base of a snow squall.[14][15] The term "winter waterspout" is used to differentiate between the common warm season waterspout and this rare winter season event. Very little is known about this phenomenon and only six known pictures of this event exist to date, four of which were taken in Ontario, Canada. There are a couple of critical criteria for the formation of a winter waterspout. Extremely cold temperatures need to be present over a body of warm water enough to produce fog resembling steam above the water's surface; this requires a 19 °C (66 °F) temperature difference between the water and the invading surface air mass. Like the more efficient lake-effect snow events, winds focusing down the axis of long lakes enhance wind convergence and likely enhance their development.[16]
