Tornadoes

The Tri-State tornado of March 18, 1925. This tornado tore through parts of Missouri, Illinois, and Indiana, killing 695 people.

A tornado warned storm is a thunderstorm for which a tornado warning has been issued, meaning that the storm is producing rotation that can spawn a tornado.

There is only one tornado that is known to have killed more than 1,000 people; the Daultapur-Saturia tornado of April 26, 1989. This tornado struck central Bangladesh, killing 1,300 people. Headlines initially reported 1,000 deaths in the Tri-State tornado of 1925, but the total was later revised to 695.

Thunderstorms arise from what is called convective instability which is a condition in which a parcel of air will become warmer than its surroundings if lifted. As the air rises it cools and the moisture in it condenses, forming clouds and eventually precipitation. The condensation also releases energy. Most thunderstorms are not severe. Thunderstorms are an important source of rainwater in many regions, and so are vital to life. In some cases the rain can lead to flooding. Lighting can kill people and animals, destroy trees, and start fires. Severe thunderstorms canse produce large hail that can damage crops and property and can kill and injure people and animals. Damaging wind gusts can also be dangerous. Severe thunderstorms can also produce tornadoes.

A tornado is a product of a thunderstorm, with most coming from an especially powerful type of storm called a supercell. Supercells develop when wind shear, differences in wind speed and direction wit altitude, sets the updraft of the storm rotating, turning it into a mesocyclone. This mesocyclone can tighten and intensify to form a tornado. A tornado produces violent winds that, in some cases, can severely damage or destroy man-made structures and pose a very serious threat to life and property. In some cases entire towns may be destroyed with dozens, or in very rare cases, hundreds killed. Large swaths may be essentially deforested.

Hurricanes (generically known as tropical cyclones) are the result of clusters of thunderstorms that organize and intensify as they feed on the evaporation of warm ocean water. These are large storm systems that produce torrential rain and violent winds. Even when they don strike land, hurricanes create large ocean waves that can pose a hazard to boats and create rip currents on nearby shores. When they hit land, the wind pushes the ocean onto shore in what is called the storm surge. This can cause severe coastal flooding. The rain on top of that can lead to severe inland flooding. 90% of people who die in hurricanes drown. The winds of hurricanes can also cause significant damage, though it is rarely as severe as damage from significant tornadoes. Thunderstorms in a hurricane's rain bands may becomes severe, with tornadoes being a common threat.

Some people believe that the tall buildings of a major city would interefere with the airflow of a tornadoes. This is not true. This myth is perpetuated by the fact that major tornadoes hitting major cities are relatively rare, simply for the fact that cities make rather small targets and the chances of any given location being hit by a major tornado are small.

Kansas aveages 95 tornadoes per year.

The Super Tornado Outbreak occurred on April 3-4 1974.

Minnesota gets tornadoes but not hurricanes. Hurricanes form over wam ocean water and do not last very long over land. Minnesota is much too far from the ocean.

Tornadoes in the United States are generally associated with collisions of air masses. In mmany cases there is a warm, moist air mass that originates over the Gulf of Mexico. This meets a cool air mass from Canada, a warm, dry air mass from the Rocky Mountains, or both.

-i was looking up the same thing!

Meteorologists knew that severe thunderstorms were possible and that some might produce tornadoes and so issued a severe thunderstorm watch. They did not include any mention of tornadoes in the forecast as they clung to the notion still prevalent at the time that forecasting tornadoes would start a panic. As a result the people were not warned of the Worcester tornado.

A Tornado to happen and then it is named after the person that reports it first :-)

Tornadoes produce a large pressure drop over a short distance. The exerts a great force on the air and cause it to reach great speeds. On top of this, on one side of the tornado, its forward speed will be added to its rotational speed. In northern hemisphere (counterclockwise) tornadoes this will be the right side, and in southern hemisphere (clockwise) tornadoes it will be on the left side. In some tornadoes, smaller vortices can develop that move with the rotation, rotating at up to 100 mph.

So that means if a tornado is moving at 30 mph (a typical speed), rotating at 100 mph, and has a subvortex rotating at 100 mph, winds on the right side of the tornado will at times reach 230 mph.

The most tornado-prone area in the U.S. is Tornado Alley, which extends from northern Texas to Iowa. The worst portion of it covers parts of Oklahoma and Kansas.

Hi. This is Nikki Longdon. I randomly seen this on google and was like HOLY COW! How weird! LoL! Anyways, I thought I would let you know that we're doing great. It was a tough struggle for the longest time, but, we're good as can get now. We have a beautiful baby daughter now that is 6 weeks old. We've finally got our and feet and appreciate EVERYTHING every's done for us. Thank you all so much! --Nicole Longdon-

The two are not neccessarily related. One describes a political ideology and the other relates to differences based on geographical regions. Very early in colonial development the colonies were divided into New England Colonies, Middle Colonies, and Southern Colonies. The regions had different life styles, economic interests, and cultural interests, but after the Revolution the idea of nationalism was embraced by the entire country, or at least enough of each state to ratify the Constitution.

Thunderstorms are the result of instability, which occurs when the lower atmosphere is warm and moist but temperature drops fairly rapidly with increasing height. Under these conditions air that is set rising will continue to rise. As it rises it cools , causing the moisture in it to condense and form a towering cumulonimbus cloud and then rain. Collisions between water droplets and ice crystals in the cold upper reaches of the storm creates static electricity that discharges as lightning, which produces a loud sound we call thunder. Thunderstorms need some sort of lifting mechanism to trigger them. Often it comes in the form of a weather front, but can come from a lake or sea breeze or interaction with the topography. Any rainstorm that produces thunder and lightning is considered a thunderstorm. Thunderstorms frequently produce heavy rain and can produce strong wind, hail, and tornadoes.

Hurricanes develop when an area of low pressure and disturbed weather, called a tropical disturbance, moves over warm ocean water. The warm, moist air from the water fuels thunderstorms. The rising air of the storms causes the pressure to drop, which then draws in more warm air to fuel the thunderstorms and increases the speed of the wind. As a consequence of Earth's spin the system will start to rotate. Through this cycle the disturbance becomes stronger and more organized. When the sustained winds of the organized circulation reach 74 miles per hour the system is considered a hurricane. A hurricane is an intense tropical cyclone characterized by strong winds, torrential rain, and large waves. Most hurricanes have a calm area at the center called the eye of the storm.

Tornadoes occur when strong thunderstorms encounter wind shear, a difference in wind speed and direction with altitude. Wind shear has two effects on thunderstorm cells. First, it separates the updraft and downdraft portions of the storm. This separation prevents rain-cooled air from choking off the updraft, an occurrence that brings about the end of an ordinary thunderstorm within 30 minutes. This new kind of storm can last for hours. Second, the wind shear sets the storm rotating. Most of the rotation is within an area of the storm called the mesocyclone. Under the right conditions a downdraft can wrap around the mesocyclone, causing it to tighten and intensify to form a tornado. Tornadoes are small but violent rotating storms that connect to both the ground and the cloud base of a thunderstorm. Air rapidly spirals windward and upward. Most tornadoes are made visible by a combination of a funnel of condensed moisture and a cloud of dust and debris kicked up by the winds.

Not necessarily, as school has been in session in areas under a high-risk outlook. However, the decision would be up to the school district, as cancellation policies differ.

No. Ada is never mentioned and the only town portrayed in the movie is Wakita.

An influx of warm, moist air into the tornado's parent thunderstorm may cause the tornado to intensify. Some tornadoes intensify as a result of becoming narrower due to the conservation of angular momentum. There is some evidence to suggest that a tornado may intensify slightly when entering a valley.

Yes to all three. Note, though that the storms that we call hurricanes are only called hurricanes in the Atlantic and parts of the Pacific in the northern hemisphere. When they occur around Australia they are called cyclones.

Yes, storm chasing can be a career for meteorologists, researchers, photographers/videographers, and tour guides who actively track and document severe weather events. They may work for government agencies, research institutions, media outlets, or private tour companies. However, it can be a risky profession that requires specialized knowledge, training, and safety precautions.

The vast majority of tornadoes are cyclonic, though it would be incorrect to call them cyclones.

Anticyclonic tornadoes are rare, accounting for less than 1% of all tornadoes.

Yes. Strong to violent tornadoes can sometimes occur near a formation called a bow echo. In some cases, the north side of a bow echo can develop a circulation similar to the mesocyclone of a supercell. One of the more unusualy cases came on April 4, 1981 when a bow-echo produced an anticyclonic F4 tornado that struck the town of West Bend Wisconsin.
