Tornadoes

First there must be an abundant source of moisture in the lower levels of the atmosphere,Next there has to be some mechanism must lift the air so that the moisture can condense and release latent heat.Last the portion of the atmosphere through which the air continue to cool with increasing altitude for the growing cloud to stay warmer than the surrounding air.

Yes. Missouri is very prone to tornadoes. On average, Missouri averages about 45tornadoes per year. Missouri was affected by three of the ten deadliest tornadoes in U.S. history, including the devastating Joplin tornado of 2011.

That usually is a factor in tornado development but more is needed. When warm and cold air collide this is usually called a front. Thunderstorms can develop along these fronts, but most never produce tornadoes.

In order to produce a tornado a storm must rotate. This rotation usually comes from something called wind shear.

Even then, most storms like this don't produces tornadoes. Why some do and some don't is the subject of ongoing research.

A tornado is a violently rotating column of air extending from the base of a thunderstorm to the ground.

Lightning is a massive discharge of static electricity that occurs during a thunderstorm.

Without a doubt the worst tornado of the past 10 years was the Joplin, Missouri EF5 tornado of May 22, 2011. This tornado killed 158 people, making it the 7th deadliest in U.S. history and the deadliest U.S. tornado since 1947. In addition, over 1,100 people were injured and damage total reached $2.8 billion, making it the costliest tornado in U.S. history.

No. A tornado is a violently rotating column of air extending from the base of a thunderstorm to the ground.

A tornado is often, but not always made visible by a funnel cloud. But the tornado is not the cloud itself.

This kind of cloud is typically called a wall cloud. Wall clouds are often associated with severe thunderstorms and can be a precursor to the development of a tornado.

A tornado's funnel cloud forms when warm, moist air rises rapidly and creates a rotating column of air. This spinning motion causes the air to condense into a funnel shape, which is visible as the iconic tornado funnel cloud.

In the Tornado Alley mostly in the mid temperatures are often70's or 80's prior to the formation of a tornado. Some other places higher or lower .

Tornadoes have been recorded in temperatures even inf the 50's.

No, sleet is a type of precipitation consisting of small ice pellets that form when raindrops freeze before reaching the ground. Tornadoes are violent rotating columns of air that form in severe thunderstorms. The formation of a tornado requires specific atmospheric conditions that sleet does not provide.

A severe thunderstorm has the potential to spawn a tornado due to the rotating updraft within the storm. Tornadoes are violent, rotating columns of air that extend from a thunderstorm to the ground and can cause significant damage. It's important to take shelter immediately and follow guidance from local authorities during severe weather events.

F5 refers to the highest rating a tornado can achieve. Such tornadoes have occasionally been referred to as the "Finger of God."

In terms of tornadoes B5 doesn't mean anything at all. However, in some tornado outbreaks supercells (the thunderstorms which produce most tornadoes) are labeled with letters and their tornadoes labeled with numbers. So B5 would indicate the fifth tornado produced by the second supercell. This says nothing about a tornado's traits.

The states that have had known F5 and EF5 tornadoes are: North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Texas, Minnesota, Iowa, Missouri, Arkansas, Louisiana, Wisconsin, Illinois, Kentucky, Tennessee, Mississippi, Indiana, Alabama, Ohio, and Pennsylvania have all had at least one F5 tornado.

Two other states worth mentioning are Georgia and Massachusetts. In 2011 a tornado rated EF5 crossed into Georgia from Alabama. However, it was in its dying stages when this happened, and was only at EF1 intensity in Georgia.

The tornado that hit Worcester, Massachusetts in 1953 was officially rated F4, but some experts believe it may have been an F5.

tornado. Tornadoes are violent, dangerous rotating columns of air extending from a thunderstorm to the ground, forming a destructive vortex.

The MOST powerful tornado that causes total destruction. Strong frame houses lifted off foundations and carried considerable distances to disintegrate; automobile sized missiles fly through the air in excess of 100 m (109 yd); trees debarked; steel reinforced concrete structures badly damaged; incredible phenomena will occur.

there are electromechanical sirens or there are sirens that have a combination of one or more loudspeakers (usually used for broadcasting voice messages). they also are either rotational sirens (horn rotates 360), or omni-directional sirens (points in all directions).

See the related links below for examples.

Tornadoes are associated with cumulonimbus clouds, which are tall, dense clouds capable of producing severe weather. Hurricanes are associated with cumulonimbus clouds as well, but they also have a distinct type called the tropical cyclone, characterized by a large circular area of low pressure with spiraling bands of thunderstorms.

When two F5 tornadoes collide, the stronger tornado would likely absorb the weaker one, leading to even more destructive winds and intensity. This collision could result in a wider and more devastating path of destruction. Additionally, it may lead to erratic and unpredictable behavior, further increasing the danger to anything in its path.

You cannot see the air itself, but you can see things that are in the air. The funnel itself is condensation. It consists of tiny droplets of water just like an ordinary cloud. Air entering tornado undergoes a rapid pressure drop which in turn causes a temperature drop. Since the air flowing into a tornado is usually moist, this causes the moisture to condense.

Tornadoes can also lift significant amounts of soil and occasionally larger debris into the air, forming a debris cloud which can sometimes engulf the funnel.

No, hurricanes do not have funnel-shaped clouds. They have a wide expanse of swirling clouds that form a dense, circular shape around the storm's center called the eye. Funnel clouds are typically associated with tornadoes, not hurricanes.

My client has asked that I fix a 4-plex basement apartment cold space under the front concrete porch that is being used as a clothes closet. Presently there are 2 - 2'' Gas lintewa through the space that contributed to some condensation on one corner of the space. They would like the space finished. What is the best approach to doing that?

Since official record keeping began in 1950 there have been 229 tornadoes recorded in Arizona. The true figure may be higher than this as in the earlier part of this period the majority of weak (F0 and F1) tornadoes were likely missed.

Thunder is created by the rapid expansion of air surrounding a lightning bolt, causing a shock wave. The four mixtures of wind involved in thunder formation are updrafts, downdrafts, horizontal winds, and wind shear. Updrafts carry warm, moist air upward; downdrafts are cold, dense air descending; horizontal winds help in the propagation of the thunder sound; and wind shear contributes to the formation of lightning.

It is possible. On the original Fujita scale wind estimates for an F0 tornado went as low as 40 mph.

On the new scale EF0 winds start at 65 mph (though some EF0 rated tornadoes have had estimated winds as low as 60 mph) as winds below 60 mph are unlikely to cause any notable damage. Some tornado touchdowns that were sighted but did not produce damage may have had winds below 50 mph. Winds in the funnel aloft will, of course, be stronger.

No. Hurricanes are massive storm systems that require large amounts of moisture to form. If there is not enough moisture for clouds to form there can't possibly be a hurricane.

Tornadoes form from thunderstorms and by definition must be in contact with both the cloud base and the ground.

There is a different sort of phenomenon, however, called a dust devil. These are whirlwinds that often form on clear, sunny days. They are not tornadoes, but they look like them. Dust devils are much weaker than tornadoes and are usually harmless.
