a Doppler rader tracks a tornado and will tell the wearther people if it's coming
A single smart person on a motorcycle with a cell phone link to another smart person at a computer connected to the internet could track a tornado. About 99% of the other stuff is just sensationalism and a means to produce some kind of "documentary" that can be sold to television. Those who are really serious about tracking down a tornado have a truck with a Doppler radar unit on it. Everyone else is just a "pretender" who in interested in film production rather than meteorology. In this light, one truck would be enough. A second truck could Cary "chasers" and the larger unit with the radar could stay out of harm's way. In that case, two trucks would do it. The use of a vehicle hauling a Doppler radar unit separates the "real players" from the "wannabes" out there - and there are a lot of the latter.
The longest tornado path ever recorded was 219 miles long.
The tornado's direction of movement is northwest at a speed of 30 miles per hour. This information helps to track and predict its path and potential impact on the area. It is important to take immediate safety precautions in response to the tornado warning.
The Tri-State Tornado, which occurred in 1925, caused widespread destruction to the environment by leveling forests, uprooting trees, and disrupting ecosystems along its path. The tornado's impact on the environment was severe due to its intensity and long track, altering landscapes in Illinois, Missouri, and Indiana.
The Great Natchez Tornado was a devastating tornado that struck Natchez, Mississippi, on May 6, 1840. It remains one of the deadliest tornadoes in U.S. history, killing at least 317 people and causing widespread destruction in the area. The tornado had a long track and reached estimated wind speeds of over 300 mph.
The widest track was that of the El Reno, Oklahoma tornado of 2013. It was 2.6 miles wide. The longest damage track was that of the Tri-State tornado of 1925. It was 219 miles long.
People might need it for evidence. The government also needs to keeps track of the tornado occurrences.
Meteorologists track tornadoes using Doppler radar, which can detect rotation in a storm, and reports from eyewitnesses.
That depends on where you are relative to the tornado. Most tornadoes travel in an easterly direction, so if you are watichng a tornado and are south of it, it will move to your right, and if you are north of it, it will move to your left.
The worst tornado damage of 2010 appears to have been in Mississippi, particularly from long-track EF4 tornado that move across the state on April 22.
That would be a tornado. Once the process starts, a tornado can form in a matter of seconds. Hurricanes, by contrast, usually take several days to form and are easy to track.
Scientists study tornadoes by scanning them with Doppler radar, measuring conditions near and before a tornado with instruments, and deploying probes inside a tornado. The last approach has met with little success.
The are various instruments that scientists have deployed. Most tornado probes carry barometers to measure the pressure inside a tornado. Some have held a variety of anemometers to measure wind speed. A few have had cameras.
The Tri-State Tornado of March 18, 1925 claimed the most lives of any single tornado, killing 689 people in 3½ hours on its 219-mile long track. This tornado also was the third-fastest tornado on record, traveling at nearly 60 miles per hour.
Packages of instruments put into tornadoes are generically called probes.
In some ways, yes. Most often the damage a tornado causes is used to estimated its peak wind speed. The peak wind estimated in turn is used to assign it a rating on the Enhanced Fujita scale. In some instances mobile Doppler radar has remotely obtained wind speed measurements from inside a tornado, though this method is limited in that it cannot measure winds near the ground where damage occurs. In a handful of cases instruments have been place in the path of a tornado and taken direct measurements. This is difficult, as most instruments cannot withstand the extreme winds of a tornado, and even then the tornado misses the instruments in most cases.
The most valuable tool is doppler radar, which can detect the rotation in a thunderstorm that can produce a tornado, and even the rotation of the tornado itself. The introduction of dual polarization in these radars can be used to detect debris lifted into the air.
