Tornadoes

Tornadoes can vary in size, but a 16-mile-wide tornado would be extremely rare and considered an exceptionally large and destructive tornado. Most tornadoes are much smaller, typically ranging from tens to a few hundred yards wide.

The United States averages about 1200 tornadoes per year, which would work out to about 3600 tornadoes in an average 3-year period.

Not exactly. A collision between a warm moist air, usually from the east, with cool, dry air, usually from the west, often results in thunderstorms. Other factors are needed for these storms to produce tornadoes.

Bulkheads are not typically designed to serve as storm shelters during tornadoes. It is safer to seek shelter in an interior room on the lowest level of a building, preferably away from windows and doors. Tornado shelters are specifically constructed to protect individuals during tornadoes, and it is important to follow safety guidelines during severe weather events.

Yes, tornadoes can strike big cities. While less common than in rural areas, tornadoes have been known to hit major cities like Oklahoma City and Dallas. Urban areas may experience less frequent tornadoes due to the presence of buildings and infrastructure, but they are not immune to tornado activity.

The U.S. experiences an average of 1200 tornadoes each year. This may sound like a lot, but it still makes tornadoes relatively rare compared to other weather events with only about 1% of thunderstorms producing tornadoes. Hundreds more tornadoes touch down worldwide, but exact statistics are unknown as many countries do not keep extensive records like the U.S. does.

The most tornado prone city in the U.S. is Oklahoma city.

Most severe thunderstorms do not produce tornadoes. If a tornado is detected or it is believed a storm might produce one a tornado warning is issued, which is more serious than a severe thunderstorm warning. A thunderstorm that produces a tornado is automatically classified as severe even if other severe weather (damaging non-tornadic wind or large hail) does not occur.

The damage is primarily wind damage, though damage can also occur from debris impacts.

Weak tornadoes (EF0 and EF1) cause minor to moderate damage. Tree branches are broken with some trees uprooted or snapped. Houses may lose roof tiles or even part of the roof structure. Weakly built structures such as barns may collapse.

Strong tornadoes (EF2 and EF3) cause considerable to severe damage. Most trees are uprooted or snapped. Well built houses will loose their roofs and even same walls. Cars can be lifted up and thrown.

Violent tornadoes (EF4 and EF5) causes devastating to incredible damage. The few trees that remain standing will be stripped of their bark and have only stubs of their larges boughs. Well constructed houses will be leveled to the ground or even wiped clean off their foundations.

A tornado warning means that a tornado has been spotted or indicated by weather radar in your area. This is a time to take shelter immediately and follow safety precautions to protect yourself from the approaching tornado.

Dayton, Ohio is located in the region known as Tornado Alley, but it is considered to be on the eastern edge of Tornado Alley. While tornadoes can and do occur in this area, they are less frequent and intense compared to the central United States.

Yes, an EF1 tornado can uproot trees. EF1 tornadoes are capable of producing winds between 86 to 110 mph, which can be strong enough to uproot trees, especially if the trees are not healthy or have shallow root systems.

After a tornado has happened, prioritize safety by checking for injuries and helping others if needed. Stay tuned to local news for updates and follow emergency instructions. Assess damage to property and contact insurance providers. Follow any evacuation orders and seek shelter if necessary.

Hurricanes are measured through a combination of satellite imagery, manned flights into the storms, Doppler radar, and ground ad seas surface based observations.

Tornadoes are more difficult because they are smaller, shorter lived, and overall less predictable. Measurements have been made using Doppler radar and ground and ground based probes. Even then, most tornadoes do not have any measurements taken, so strength is estimated based on the damage caused.

you would call it, 1. Geophysicist - They measure, examine, and explore the physical properties of earth, from below the ground to the atmosphere, from the depths of the ocean to the tops of mountains

or, 2. Atmospheric Scientist - They study the atmosphere's physical characteristics, motions, and processes, and the way in which these factors affect the rest of our environment.

and last 3. Meteorologist - They explain, understand, observe or forecast the earth's atmospheric phenomena and/or how the atmosphere affects the earth and life on the planet.

Tornadoes are produced by thunderstorms. Warm moist air has vast amounts of latent heat stored in water vapor. As this warm air rises, often due to an encounter with a front, it cools but so does the air around it. When this air reaches a certain temperature called the dew point the moisture condenses, releasing its heat energy and slowing the rate of cooling. This mass of air becomes warmer than its surroundings and thus less dense and more buoyant, creating a thunderstorm. If enough of this energy is present and if a few other conditions are right, this thunderstorm may have the potential to produce tornadoes.

No, that is a complete myth. It is the wind and debris in a tornado that destroys buildings.

First the pressure drop is not enough to cause significant damage to a building. The largest reliably recorded pressure drop in a tornado was 100 millibars, but a pressure difference of about 350 millibars is needed to destroy most buildings.

Second, buildings are not airtight so pressure will equalize quickly.

Third, even if the two statements above were not true the winds and debris in moderate to strong tornado would create enough holes to equalize pressure, if not destroy the building before the center of the tornado (where the lowest pressure is) reaches it. A tornado with a 100 millibar pressure drop would produce winds strong enough to completely level most structures.

After a tornado destroys their house, people may seek temporary shelter in emergency shelters set up by local authorities or relief organizations. They may also stay with friends or family members if possible. Insurance coverage may also help with finding temporary accommodation or rebuilding their home.

A Tarasoff warning is where a mental health professional is required to warn of a credible danger to a reasonably identifiable victim. It was derived from the 1976 case Tarasoff v. Regents UC Berkeley.

No, the center of a tornado is known as the "eye" and it is actually an area of low pressure where air is rising, not descending. The strongest winds in a tornado occur around the edge of the eye in a region known as the "eyewall."

The peak months for tornadoes in Texas are typically April, May, and June, with May being the busiest month. This is when warm, moist air from the Gulf of Mexico interacts with cooler, drier air from the north, creating the conditions for severe weather outbreaks.

There is no such thing as an F6 as damage maxes out at F5. F5 damage consists of the complete destruction of nearly all structures. Well-constructed houses are wiped clean off their foundations.

Tornadoes can form near a variety of boundaries. They can form along a cold front, dry line or, less often, a warm front. Two prime locations for tornado formation are Larko's triangle and the triple point. Larko's triangle is an area near the center of a mid-latitude low between the cold front and the warm front. The triple point marks where a cold front and dry line intersect.

In any case, the fronts are not the direct causes of the tornado and are not absolutely necessary for one to form. Some tornadoes can form away from fronts, such as in the outer bands of hurricanes. In almost all cases, however, a warm, moist (maritime tropical) air mass is present.

Most likely not, as the chances of having two tornadoes close enough to merge is unlikely. However, some tornadoes, especially large, violent ones, somtimes have a series of smaller vortices inside the main vortex of the tornado. Under the right conditions these vortices can become visible, resulting in a tornado with multiple funnels. Tornadoes with four or more funnels have been observed. In some instances, these vortices will be visible for a time and then suddenly become hidden within the main funnel or debris cloud, making it look like they have merged.
