Tornadoes

Yes. The worst tornado to have hit the UK in modern times was a T5 (equivalent to a strong F2) which hit Birmingham in July of 2005, costing £40 million (about $70 million US). This is a rather significant tornado, even by US standards. The strongest known British tornado struck Portsmouth in 1810. It was estimated to have been a T8, equivalent to an F4.

There are actually six levels of tornado intensity. The EF0 (formerly F0) category is often forgotten. Tornadoes in the U.S. are rated on the Enhanced Fujita (EF) scale, which relplaced the Fujita (F) scale in 2007. While there have been adjustments to the wind speed estimates, ratings are essentially equivalent.

EF0 (65-85 mph): Shingles, siding, and gutters peeled from structures. Tree limbs broken with some trees toppled. Fences are blown down and some very weak structures may be destroyed.

EF1 (86-110mph): Roofs of houses severely damaged with some poorly secured roofs removed. Trailers homes are overturned or badly damaged. Barns and garages may collapse.

EF2 (111-135 mph): Roofs are torn from well-built houses but most walls remain standing. Trailer homes and sturdy barns are completely destroyed. Some cars are tossed short distances.

EF3 (136-165 mph): Roofs and walls torn from well-built houses. Sometimes only a few interior walls remain. Many weaker structures are destroyed or blown away.

EF4 (166-200 mph): Well constructed houses are leveled and left as piles of rubble. Weaker homes may be blown away. Trees may be debarked. Asphalt may be peeled from roads.

EF5 (over 200 mph): Well contructed houses are completely swept away, leaving empty foundations. Reinforced concrete structures are destroyed. Severe ground scouring may occur.

The appears to be asking about multiple vortex tornadoes. The process of how a tornado becomes multiple vortex is called vortex breakdown. Thi occurs when the wind in a tornado is spinning so fast that it cannot reach the center. The low pressure instead draws air down the middle. This causes the tornado to expand. When the downward moving air reaches the ground it spreads out. Complex interactions between this outward moving air and air flowing into the tornado leads to the formation of smaller vortices within the tornado.

The Great Natchez tornado was never rated. The Fujita scale, which rates tornadoes, was crated in 1971, but has been used to rate tornadoes retrospectively. To rate a tornado you need information on the severity of the damage it did and the quality of construction of the buildings it hit. Unfortunately, as you look at older records, there is generally less useful information. Because of this, no tornado that occurred before 1871 has received a rating. The Natchez tornado was in 1840.

That said, by comparing this tornado with other major killers, it is reasonable to say that it was probably an F4 or F5.

Meteorologists use a variety of tools to predict and detect tornadoes, such as weather radar, satellites, weather balloons, and computer modeling. Doppler radar is especially important as it can detect rotations within storms that may indicate the formation of a tornado. Additionally, meteorologists rely on storm spotters, tornado sirens, and public alerts to provide warnings to the public when a tornado is approaching.

A tornado is short term, usually lasting minutes to hours. It forms as a result of rapidly rotating air associated with severe thunderstorms and typically moves quickly along a narrow path. Once a tornado dissipates, it no longer exists.

The primary destructive force in a tornado is wind. The intensity varies, but the wind in a strong enough tornado can easily carry more force than most structures can withstand. Some pieces of destroyed structures can then turn into high-speed debris, which adds to the destruction.

Tornadoes are relatively rare in Europe compared to regions like the United States. The frequency of tornadoes in Europe varies by country, but they typically occur a few times a year in the most tornado-prone areas. Further research and analysis are needed to better understand the dynamics of tornado occurrence in Europe.

Florida generally experiences more tornadoes than Arizona. This is due to the geographical location and climate of Florida, which is prone to severe weather conditions that are conducive to tornado formation, such as strong thunderstorms and hurricanes. Arizona, on the other hand, has a drier climate and is less prone to tornadoes.

The extremely powerful winds of a tornado cause the most damage. Debris carried by the wind is also very damaging, but exactly how much of the damage is caused by debris or wind is unclear and likely varies considerably depending on the tornado and where it occurs. Debris is a more significant factor for a tornado that goes through a town than for one that only hits isolated farms.

Tornado season in Fort Myers, Florida typically occurs from late spring to early summer, peaking in June. However, tornadoes can occur at any time of the year due to the region's warm and humid climate. It's important to stay informed and have a plan in place to stay safe during tornado season.

It varies widley. Most tornadoes last a few minutes, with many lasting just a few seconds. However, the most destructive tornadoes can last half an hour or more. The longest-live tornado on record lasted for 3 hours and 29 minutes.

Tornadoes are most frequent in the central plains of the United States, often referred to as "Tornado Alley." This region includes parts of Texas, Oklahoma, Kansas, and Nebraska. Tornadoes can occur throughout the year, but peak season typically falls between April and June.

There is no solidly set minimum wind speed for a tornado. The Enhanced Fujita scale starts an EF0 at 65 mph, but tornadoes have occurred with estimated winds lower than that. Tornadoes are defined by the amnner in which the air moves rather than the wind speed. A tornado is a rotating vortex of strong wind that onnects to both the ground and the cloud base.

There are six levels on the EF (Enhanced Fujita) scale running from EF0 at the weakest to EF5 at the strongest.

There is a good chance of one happening some time in the future, as Garden City has been hit several times in the past 65 years. However, there is no way of knowing when the next one will hit.

Yes, there have been tornadoes in Wolcott, Connecticut. The most recent tornado in Wolcott occurred on May 15, 2018, rated EF1. Wolcott has experienced a few tornadoes in its history, with varying intensity levels.

There were 325 tornadic fatalities from the April 25-28 2011 tornado outbreak of which 320 were on April 27.

Yes, a snow tornado, also known as a snow devil or snow whirlwind, can form in certain conditions where a vortex of air picks up snow from the ground. However, snow tornadoes are not as common as their warm-weather counterparts.

It is too early to tell. Currently the area under the high-risk outlook is covered by two tornado watches, which discuss the non-tornadic threats that would be covered by a severe thunderstorm watch.

No. The apparent increase in tornado activity through the 20th century is the result of improved detection of smaller, weaker tornadoes. The activity of strong to violent (F2-F5) tornadoes in the United States has actually decreased overall since the 1950s and 1960s.

Low-topped cumulonimbus clouds can easily bring thunderstorms. Tornadoes are less likely than in a high-topped storm, but are still possible.

If you are referring to cumulonimbus clouds with a low base, then yes. In fact, tornadoes develop mor easily in low-based storms.
