Tornadoes

Tornado Alley is a region in the central United States that is particularly prone to tornadoes. It includes parts of Texas, Oklahoma, Kansas, Nebraska, and South Dakota. This area experiences a high frequency of tornadoes due to the clash of warm, moist air from the Gulf of Mexico and cool, dry air from the Rocky Mountains.

That record is held by the dates running from Friday, April 22 to Thursday, April 28, 2011 during which there were 392 recorded tornadoes in the U.S. More than half of these occurred on April 27.

Dallas is at least 250 miles inland. By the time a hurrricane reaches Dallas it usually becomes a tropical storm (lots of wind & rain). Its not impossible (though quite improbable) that a hurricane could sustain enough strength to be classified as such when it reaches Dallas, such a storm would be extremely rare.

In Canada tornadoes are most likely to occur in Saskatchewan,MANITOBA and Ontario.So it does,but these are just Canadian places.No need to worry because they don't happen often...if they do they last around a couple of minutes(or a little longer)and they usually happen around may-august

Hurricanes produce large waves, heavy rain, and extensive flooding, all of which can cause severe erosion, especially along coasts.

Tornadoes, especially strong ones can lift large amounts of soil into the air and pull vegetation from the ground, leaving the soil vulnerable to further erosion.

During a tornado, go to a basement or an interior room on the lowest floor of a sturdy building. Avoid windows, doors, and outside walls. Do not stay in a mobile home or seek shelter under a bridge or overpass.

Fist you need air that is warm and moist. Air like this is often unstable, which allows it to produce thunderstorms. Then you need something to trigger these storms. Usually it is a mass of cooler or direr air colliding with the original air mass, though sometimes the storms may be triggered by a hurricane or other storms system moving in. You also need wind shear. This is ultimately what gives the storms the rotation they need to produce tornadoes.

Yes, tornadoes and hail can occur together during severe thunderstorms. The strong updrafts and turbulent conditions within a thunderstorm can create hail, while the rotating updraft required for a tornado can also contribute to hail formation.

Most likely it is part of an assessment of the actual risk involved. The hatched area refers to significant severe weather, meaning wind gusts to hurricane force and tornadoes of EF2 or higher intensity. It is these events which pose the greatest risk to life and property.

No tornado hit Joplin, Missouri in 2012. However, Joplin was devastated by an EF5 tornado on May 22, 2011. That tornado directly killed 158 people, the deadliest to hit the U.S. since 1947. Three or four other people died due to indirect effects.

Tornado Activity is monitored by the National Weather Service.

Yes, tornadoes have occurred on all continents except Antarctica and have occurred in virtually all climates except for some regions of polar climate or extreme desert.

Countries other than the U.S. with high tornado activity include Canada, Australia, Argentina, Bangladesh, and South Africa.

Tornadoes can cause widespread destruction by uprooting trees, damaging buildings, and hurling debris at high speeds. They can also result in injuries and fatalities, as well as leave behind a path of devastation. Additionally, tornadoes can disrupt infrastructure, such as power lines and transportation systems, leading to further challenges for affected communities.

There are a number of factors. One of the major factors is how hard a building is hit. Most tornadoes are technically classified as "weak" with ratings of EF0 and EF1 and estimated winds of up to 110 mph. While a 110 mph wind can be very damaging, most decently sturdy structures will remain standing. The tornadoes that cause destruction worthy of national headlines account for a small percentage.

Even when a tornado is given a higher rating, the intensity only refers to the worst of the damage caused. Buildings not hit by the worst winds are likely to be less heavily damaged. Peak winds inside a tornado can vary greatly over short distances. One house may be impacted by a 250 mph wind, which almost nothing can withstand, while a nearby structure may experience winds of less than 100 mph.

Quality of construction is a major factor as well. When it comes to tornadoes, the buildings that are most likely to survive are those that have their parts strongly held together

That can have several answers.

The strongest (though not necessarily the largest) tornadoes are EF5 tornadoes with estimated winds over 200 mph.

The strongest tornado recorded (or at least to have its wind speed measure) had winds of 318 (some say 302) mph.

The widest tornado ever recorded struck Hallam, Nebraska tornado in 2004. It was 2.5 miles wide.

A tornado can cause significant damage to Earth's surface by uprooting trees, demolishing buildings, and tossing debris. The high winds and intense pressure changes can also alter the landscape by flattening vegetation and creating new paths through the terrain. Additionally, tornadoes can contribute to soil erosion and disrupt ecosystems in the affected areas.

The Gulf of Mexico provides warm, moist air.

Man-made structures and vegetation may be severely damaged or destroyed, but the land itself is generally not directly affected. In some instances the most violent tornadoes will scour away the topsoil, but this is a very rare occurrence.

EF5 (formerly F5) tornadoes cause the most severe damage. In these tornadoes well-constructed houses are completely swept away, leaving behind empty foundations. Some steel reinforced concrete structures are destroyed. Trees are completely stripped of their bark, roads may be peeled up, and the topsoil can be scoured away.

Meteorologists and weather professionals monitor tornado activity using a variety of tools and technologies, including Doppler radar, satellite imagery, and ground-based weather stations. They also rely on storm spotters, who are trained individuals that report tornado sightings in real-time to help keep communities safe. Additionally, the National Weather Service issues tornado warnings based on the data and observations gathered from these sources.

The Waco, Texas tornado of 1953 killed 114 people.

Much of the central U.S. is in Tornado Alley, a region of the United States that has the highest amount of tornado activity in the world. The region is the site of frequent collisions of warm, moist air from the Gulf of Mexico, cool air from Canada, and dry air from the Rockies. These collisions result in very strong thunderstorms, with the moist air acting as their "fuel." Additionally, the region often has a layer of stable air called a cap that suppresses storms. This behaves like the lid on a pressure cooker, allowing the atmosphere below it to become increasingly unstable until storms develop explosively. Finally, the region often sees strong vertical wind shear, or a variation of wind speed and direction with altitude. This tilts them in such a way that the updraft and downdraft portions becomes separated and don't interfere with one another, letting the already strong storm further strengthen and last longer. The wind shear also sets the storms rotating, turning them into supercells, the most powerful thunderstorms on earth. It is the rotation within these supercells that can develop into a tornado.

Other parts of the world do see such conditions and thunderstorms at least occasionally, but not with the same frequency as in Tornado Alley.

A scale-based strategy involves increasing production or expanding operations to reduce costs and increase efficiency. This approach relies on economies of scale to achieve lower unit costs as the volume of production increases. By maximizing output and taking advantage of bulk discounts, companies can improve their competitiveness and profitability.

On a field map, the winds are the strongest when the isobars are very close together, and the pressure gradient is high.
