Tornadoes

The word tornado coms from the Spanish word "tornada" meaning thunderstorm and "tornar," meaning "to turn."

Tornadoes are a type of severe weather phenomenon that occurs due to specific atmospheric conditions, such as warm, moist air colliding with cooler, drier air. They are a natural occurrence and are not directly caused by human activities. However, climate change may influence tornado formation by altering weather patterns, but it does not directly cause tornadoes.

The 1979 Wichita Falls, TX tornado formed along a stationary front near the Red River and quickly intensified into a powerful F4 tornado. The tornado traveled through residential areas in Wichita Falls, causing significant damage and loss of life.

There have been estimated at least 109 F5 tornadoes in the U.S. Since the introduction of the Enhanced Fujita scale there have been 9 EF5 tornadoes, which is essentially equivalent to an F5.

Note that this number should be taken with a grain of salt as it can be difficult to distinguish between F4 and F5 damage, especially in records that must be evaluated based on historical accounts.

Hurricanes cover larger areas than tornadoes. Hurricanes are large, rotating storms that can span hundreds of miles, affecting wide regions with strong winds and heavy rain. Tornadoes, on the other hand, are usually much smaller in size with a narrow path of destruction, affecting a more localized area.

Tornadoes can occur along a warm front, but you are more likely to find them along a cold front or dry line. Tornadoes can also occur in the absence of any sort of front. Warm fronts often produce precipitation but don't usually result in severe weather.

No. The Tuscaloosa tornado of 2011 was a high-end EF4. According to the survey results published from the National Weather Service the winds in that tornado fell about 10 mph short of an EF5.

Interestingly, one article suggests that had the Tuscaloosa tornado occurred before the Enhanced Fujita scale was implemented in 2007 it would likely have been rated F5. However, the newer scale has more precise standards for ratings, and, by the slimmest of margins this tornado did not meet the EF5 standard. Looking at what this storm did, it was about as bad as a tornado can get without being an EF5.

4 other tornadoes that occurred on the same day were rated EF5.

Yes, tornadoes can occur in Norristown, Pennsylvania. The area is not immune to tornado activity, although occurrences may be less frequent compared to regions in the central United States known as "Tornado Alley." Residents should remain prepared and informed about severe weather alerts in the area.

It varies from year to year, but on average Kentucky gets 22 tornadoes annually.

Eventually, yes. New York, both the state and the city, get tornadoes. However, there is no way of known when these tornado will happen.

They don't. Washington and Oregon are among the ten states that get the least tornadoes. This is because the cold water of the Pacific Ocean stabilizes the atmosphere, making it difficult for the storms that produce tornadoes to form.

No. There wasn't even a warning. The tornado was detected, but due to communication problems the warning was never issued.

Additionally, when a tornado is coming the advice is usually to take cover rather than evacuate, as there usually isn't enough time for an evacuation.

Fort the most part that is limited to tornadoes in the northern hemisphere. Nearly all southern hemisphere tornadoes rotate clockwise.

Tornadoes are formed from thunderstorms called supercells, and get their counterclockwise rotation from the rotation in those storms. The storms get their rotation from wind shear, or differences in wind speed and direction with altitude. In the northern hemisphere the wind shear is usually counterclockwise with increasing altitude. For example the wind at ground level may be out of the west while higher up it is out of the south, so it shifts in a counterclockwise manner. This can impart a counterclockwise spin on the updraft, or rising air current of a thunderstorm.

Non-examples of a tornado:

- hurricane

- dust devil

- wind storm

- blizzard

It varies from year to year, but on average Indiana gets 24 tornadoes annually.

A thunderstorm has to be pretty strong in most cases, though strength alone isn't enough. A thunderstorm needs to have rotation to produce a tornado, though the strongest thunderstorms, called supercells, rotate anyway. A tornado warning is usually issued if doppler radar detects a difference between inbound and outbound winds of 100 mph or greater, though a warning may be issued in lseer conditions.

Tornadoes are most prevalent during the spring and early summer months in the United States, typically from March to June. The peak season varies depending on the region, with Tornado Alley experiencing the highest frequency in late spring. Conditions that favor tornado formation include warm, moist air colliding with cold, dry air, usually in the presence of a strong jet stream.

You can study tornadoes at home by researching online resources, reading books or scientific articles about tornadoes, and watching documentaries. You can also follow meteorologists on social media for updates and monitoring severe weather patterns. Additionally, you can participate in citizen science projects that involve reporting weather observations.

In most cases the "fuel" for thunderstorms, including the ones that produce tornadoes is warm moist air.

Such air is more common in spring than winter. The cold air more common in winter usually does not have enough energy to produce severe thunderstorms.

Tornado do happen near and on the coast. It just so happens that the areas that get strong tornadoes (the tornadoes that get all the attention) happen to be inland. The strong thunderstorms that produce most tornadoes form most easily when warm, moist air collides with cool and/or dry air along with a few other conditions. These meet most ideally in inland areas but tornado outbreak along coasts have also ocurred.

Seek shelter. If you can get yourself underground, that's the best place to be. Although many people assume overpasses provide a safe haven this is far from the truth; they are by far the worst place to be as a large tornado will easily suck you out. See related links for video of the infamous 1991 tornado in which a group survived a small tornado under an overpass, and a link to tornado myths.

Fast-moving clouds can indicate turbulent atmospheric conditions, which may be associated with thunderstorms and potential tornado formation. However, it is not a definitive sign of a tornado on its own. Other factors, such as low-hanging or rotating clouds and severe weather warnings, are important to consider in determining tornado risk.

Hurricanes and tornadoes are different weather phenomena.

A hurricane is a tropical storm, developed over warm seas and form into large wind patterns of 100 miles or more across. It is the warm water that sustains a hurricane so it will lose energy and die out as it travels inland.

A tornado develops over land and is a funnel of spiraling air, rarely more than a few hundred feet across where it touches the ground. As well as being much more localized, they do not rely on large bodies of water to form.
