Tornadoes

Yes, tornadoes are not a significant factor in the weathering of rocks. Tornadoes mainly cause physical erosion by moving and transporting rocks and sediment. Other factors like water, wind, and temperature fluctuations play a larger role in the chemical and mechanical weathering of rocks over time.

The Doppler radar itself does not predict tornadoes, meteorologists do.

Doppler radar can detect the signature of a possible tornado, but it usually takes reports from weather spotter to confirm a tornado is occurring.

The meeting of warm, humid air and cool, dry air is not the direct cause of tornadoes. The boundary where these air masses meet is called a cold front, as the cooler air mass is advancing. Cool, dry air is denser than warm, moist air. As a result, the cooler air mass acts as a wedge, forcing the warm, moist air upward. As the warm air rises it cools and the moisture in it condense. If it is unstable enough, this will lead to the formation of thunderstorms. If a few other conditions are right, these storms may go on to produce tornadoes.

There does not appear to be such an incident based on a look at available data. Such a situation is unlikely to arise, since the Storm Prediction Center is in charge of issuing both severe weather outlooks and tornado watches. If it saw fit to issue a PDS tornado watch, it would likely issue a moderate or high risk outlook as well.

No, tornadoes are typically associated with dark or black funnels due to the debris they pick up. The color of a tornado is determined by the materials it has sucked up and the lighting conditions around it.

This means that there is a chance of tornadoes occurring in a few isolated areas. It suggests that tornadoes may form sporadically and not affect a wide area. Residents in the affected areas should stay alert and be prepared to take necessary safety precautions.

No, a tornado could not have lifted up the Titanic as it was a massive ship weighing over 46,000 tons. Tornadoes are powerful weather phenomena but they do not have the force to lift such a heavy object out of the water.

It is difficult to determine, but the heaviest objects lifted by a tornado appear to be a set of three oil tanks, each weighing 90 tons. The tornado struck Pecos County, Texas on June 1, 1990. The tornado was officially rated F4 as it hit few structures, but of ground scouring and the carried oil tanks suggests that the tornado's intensity was well into the F5 range.

It is safer than flat ground or flimsy structures, because a) you are less directly in the wind flow, and b) you are out of the path of some of the debris being carried by the wind. An enclosed underground or concrete structure is the only truly safe refuge, as bridges and culverts can funnel the wind, dust, and debris.

No, not one that is full of fuel. Rockets weigh tens or hundreds of tons, and it is much more likely that it could blow one over. Even then, they are typically connected quite strongly to a gantry until just before launch.

Tornadoes may lift trucks and train cars briefly, but that is because of their lower average density and large surface areas. Heavier vehicles such as locomotives, bulldozers and steamrollers are seldom if ever lifted airborne.

I searched and I found out that since 1851, when hurricane record keeping began, Florida has seen most of the nation's hurricane action. No other state even comes close. Of the 277 hurricanes that have hit the U.S. coastline, 112 hit Florida. Of the 96 major hurricanes (a Category 3, 4 or 5) to batter the United States, 37 barreled into Florida. ................(source: sarasotamagazine.com) According to Hurricane City.com Sarasota has the following history (br)=brush (ts)=Tropical Storm (bd)=Back Door,meaning coming from over land from opposite coast.Not all names are noted,also storms before 1950 were not named.Not every stat on every storm description is given(since 1871).

Louisiana averages 38 tornadoes per year, but the number of tornadoes in any given year can vary significantly.

Yes. The storm prediction center has specifically mentioned the threat of tornadoes and anticipates that the threat will increase as the front shifts. Given the large area placed under a moderate risk (though this may be due to the hail threat), there is likely some potential for strong tornadoes. More information will become available when the first Day 1 outlook for April 3 is issued at around midnight central time.

No. Supercomputers are used to run forecast models, which are used for longer time frames of hours to days. Such models can predict that tornado activity may occur across a region on a given day, but cannot predict where or when individual tornado will form.

Down to the minute forecasts are made using Doppler radar images and, in some cases, eyewitness reports. Human meteorologists then judge, based on this information, whether a tornado warning is warranted. Computer forecast models are useless in these scenarios, as they take too long to run.

A tornado is a localized and violently destructive windstorm occurring over land characterized by a funnel-shaped cloud extending toward the ground, coming into contact with this can literally tear a building to pieces.

Yes. Tennessee is a tornado-prone state, and no location is "safe" from them. Knoxville has had 3 or 4 recorded tornadoes since official records began in 1950, with more tornadoes occuring in the surrounding areas.

The 2013 Moore tornado happened in much the same way that other violent tornadoes happen.

A slow-moving low-pressure system moved out over the Great Plains. The collision of warm, moist air from the Gulf of Mexico, cool air from Canada, and dry air from the Rockies associated with this system caused severe thunderstorms to develop across the Great Plains. Strong wind shear set some of these storms rotating, turning them into supercells, the kind of thunderstorm most likely to produce a tornado. Some of these did go on to produce tornadoes. On May 20, a particularly intense supercell spawned a tornado near Newcastle, Oklahoma. The west-northwest track of this tornado, a common direction to take, sent this tornado straight through Moore.

The central region of the US, known as "Tornado Alley," has the highest incidence of tornadoes. States like Texas, Oklahoma, Kansas, and Nebraska experience a high frequency of tornadoes due to the clash of warm, moist air from the Gulf of Mexico and cool, dry air from the Rockies.

Scientists keep track of the number of tornadoes that hit each month to monitor trends, patterns, and changes in tornado activity. This data helps improve forecasting and preparedness efforts, as well as study the impacts of climate change on tornado frequency and severity. Tracking tornadoes also helps identify high-risk areas and develop strategies to mitigate potential damages.

There can be a few explanations for this. Most tornadoes start developing a few miles above the ground and descend from the clouds to make contact for the ground. This usually results in a visibly descending funnel cloud. However, if the air under the parent storm is dry, the funnel, which is formed from condensed moisture, may not form. In such a case, the developing tornado may be invisible until it reaches the ground and starts lifting dust, giving the ppearance that it is forming upwards.

Another potetial case of this is with landspouts. These are relatively weak tornadoes that develop without a larger mesocyclone. Landspouts form as low-level rotation in the atmosphere gets caught in the updraft of a thunderstorm and is stretched and intensified into a tornado.

Some data from Doppler radar suggests that some tornadoes in supercells form from the ground up rather than the clouds down as conventional thinking goes. Scientists are still unsure of how this happens.

6pm is typically considered to be evening, as it is after 12pm (noon) and closer to nighttime.

There is no real set lower limit for the wind speed of a tornado. The Fujita scale starts wind speed estimates for an EF0 tornado at 65 mph, but some tornadoes have had estimated winds as low as 55 mph. On the original Fujita scale, F0 wind estimates start at 40 mph. Actual wind measurements from tornadoes are rare, so winds are usually estimated from damage. Many tornadoes, expecially some short-lived, weak ones, stay in open fields and never cause damage, making it impossible to estimate wind speed.

Generally speaking, you want to be as low to the ground as possible during severe tornado conditions. A basement is ideal, as particularly powerful tornadoes can tear buildings apart. If you don’t have access to an underground space, being near the center of the building is the next best plan, staying away from any windows, as flying debris is one of the greatest dangers during these storms. If your interior bathroom has a bathtub, that can also be a sturdy place to stay safe.

Tornadoes generally do not form over large bodies water and usually only cross lakes, ponds and rivers. Their brute strength is equally powerful over land and these small bodies of water. Tornadoes have been known to dry lakes on occasion and cause fish to rain on people's houses in rare instances.

No. Tornadoes have been recorded in Girardville since official records began in 1950 and no significant tornadoes (F2 or stronger or causing a death) have ever been recorded in Girardville. However, at least one tornado has been recorded near the town: an F0 that touched down just outside Fountain Springs in 1954. Tornadoes as strong as F2 have been recorded elsewhere in Schuylkill County, so even if it hasn't been hit yet, that doesn't meant it can't be hit.
