Tornadoes

Any tornado can be dangerous. An F5 tornado is extremely dangerous. Hit by the full force of an F5 tornado, even the strongest houses will be swept away. Many F5 tornadoes are quite large, capable of leveling whole neighborhoods and killing dozens in a matter of minutes.

Tornadoes kill 60-80 people in an average year.

The main application is to use the data to study patterns in wind speed, wind direction, and baromentric pressure at ground level in a tornado. This holds an advantage as Doppler radar, which is also used in studying tornadoes, generally cannot gather data from the 50 feet or so portion of a tornado. The behavior of winds at ground level is worth studying because that is where damage occurs.

Alabama gets plentiful warm, moist air from the Gulf of Mexico. This is essentially the fuel for thunderstorms. These storms are often triggered when a cold front moves through. When these storm emerge, wind shear, or differences in wind speed and direction at different altitudes, sets the storms rotating, turning them into supercells. The rotation in these supercells can then lead to the formation of tornadoes.

Keeping track of where and when tornadoes occur, among other things, helps verify the accuracy of predictions. Patterns in tornado occurence are also useful in risk assessment.

Tornado studies now currently involve trying to examine the tornado with scientific instruments. Chief among them is Doppler radar, which can analyze wind speeds in a storm from a distance. Other work has involved trying to take measurements directly from inside the funnel using probes placed in the path. Other scientists have built computer models to try to understand tornado dynamics. Analysis has also been done on patterns in damage and debris in tornadoes.

The closest match appears to be an event on March 21, 1932. As part of a major outbreak, a series of tornadoes skipped across several counties in Tennessee. Estimates of the path show it going across the southern part of Nashville, near Brentwood.

No. The storm that spawned the Moore tornado was not seeded; there was no reason to. There is also no substantial evidence that cloud seeding affects tornadoes. Violent tornadoes are a natural occurence that will happen and strike communites regardless of any of our attempts to influence the weather.

Yes, there are quite a few. Alabama averages about 45 tornadoes per year and rivals Oklahoma in the number of F5 tornadoes it has recorded.

Immediately go to a protected location. If you have a basement or storm cellar, go there. If you don't have one, then go to an interior room, hallway, or closet on the lowest floor with no windows. If you have a sturdy table, you can crawl underneath the table. If the house collapses, you have a chance that the table can protect you. A bathroom and bathtub may also be recommended if other suitable rooms are not available. Mobile homes should be abandoned for nearby sturdier shelter. Contrary to popular belief, you should should not open windows. This does nothing to protect your house and only wastes valuable time.

Tornadoes can form in most parts of the world and over almost any terrain. They are somewhat more likely to form over flat areas, but contrary to popular belief, they can and do strike hilly and mountainous areas. Tornado activity is influenced more by climate than by topography. Areas of high tornado activity include North America between the Rockies and Appalachians, Bangladesh and India, Australia, parts of Europe, northern Argentina, and South Africa.

They are generally not as strong as the tornadoes that occur in the Great Plains, with comparatively few tornadoes reaching more than F2 strength. That said, a few tornadoes in Florida have been significant killers. One the the most notable was the Kissimmee F3 tornado of 1998, which struck two trailer parks, killing 25 people.

The of April 25-28 2011. There were over 350 tornadoes in the whole outbreak with 207 in a 24 hour period on April 27.

If you have insurance that include tornado damage, the insurance company will pay. If you haven't, the property owner has to pay himself. Cost of life.

Tornadoes do not recieve formal names like hurricanes do, but are generally referred to by the place they hit. The Joplin tornado is referred to as such because it hit the city of Joplin, Missouri.

No. A tornado is a microscale storm, as very few tornadoes get to be over 2 kilometers in diameter.

colloquial means 'slang' e.g 'watssup'

Tornadoes can strike anywhere in the Philippines.

Yes. Tornado warnings are now a common part of severe weather alerts.

Yes. Tornadoes are often made visble by condensation in their funnels and by dust and debris. However, some tornadoes may be obsured from view by rain or the dark of night.

There is no single color associated with tornadoes. The sky will often have the typical gray of storm clouds. However, in some instances the clouds may appear black, green, yellow, or blue. Even when such cloud colors do occur, they do not necessarily indicate a tornado, just that the storm is intense.

mostly strong but verry little weak and violent tornados

That depends on which tornado you are referring to. St Louis has been hit by many tornadoes.

The St. Louis tornado of 1896 had a cost of about $20 million at the time, which is equivalent to a bout $570 million in modern amounts.

The St. Louis tornado of 1927 cost about $22 million at the time, equivalent to about $300 million today.

The St. Louis tornado of 2011 had a cost of about $30 million.

Typical damage for each level of the Enhanced Fujita scale is given below. Damage in a given scenario may recieve a different rating from what is presented here based on quality of construction and other factors.

Note that only a single instance of a given level of damage is needed for a rating, i.e. if a single house takes EF3 damage, and there is no higher damage, then the tornado will be rated EF3.

EF0: Shingles and siding peeled from houses. Weak trees may be toppled. Some tree limbs may snap. Some fences knocked down. Very weak structures may be destroyed.

EF1: Houses suffer severe roof damage, with large sections of surface removed. Poorly connected roofs may be completely torn off. Trailer homes may overturned or partially destroy. Barns and garages destroyed.

EF2: Roofs torn from well-built houses. Some exterior walls may collapse. Trailer homes completely demolished. Barns blown away. Utility poles snapped or flattened.

EF3: Exterior and interior walls fail in well-built houses. Upper stories may be removed. Weaker houses completely leveled. Steel transmission towers crumpled. Weak or poorly anchored structures blown away.

EF4: Well-constructed houses completely leveled and left as piles of debris. Some houses may be blown away. Trees debarked and denuded. Asphalt may peel from some roads.

EF5: Well-constructed, well-anchored houses blown away with foundations wiped clean. Steel-reinforced structures completely destroyed. High-rise buildings deformed.

In an area hit by an F0 tornado you are likely to see broken tree limbs and a few downed trees. Roof tiles, vinyl siding, and gutters may be peeled from some structures, but usually not in significant amounts. Fences and unanchored objects may be overturned. Some very weak structures such as sheds may be destroyed.

You will see much of the same from an F1 tornado, though with more severe damage in some places. Roofs can be severely damaged and porches collapsed. Structures such as garages and barns may be destroyed. Roofs that are not well secured may be torn off.
