FC: North Texas Tornadoes of April 2012 | By: Madison Brenner
1: On April 3rd and 4th 2012, over a dozen tornadoes touched down throughout the DFW area. Hundreds of homes were damaged. 20 injuries were reported, but there were no deaths.
2: These tornadoes were caused by moisture coming up north from the Gulf of Mexico. There was also a powerful area of low pressure coming down south from the Rocky Mountains. When the moisture and the pressure collided, they created many tornadoes throughout DFW.
4: The tornado in this video was an EF2. http://www.youtube.com/watch?v=Y4pvlt_rrnk | Tornadoes don't really have an instrument used to measure them. We mainly rely on Doppler radars, like we see on the news. The tornadoes are usually indicated by a rotating circle on the spot where a tornado is. However, the Fujita Scale is used to find the intensity of the tornado by the damage that it has caused. This is how all the tornadoes are classified. The data collected after tornadoes is given to the National Oceanic and Atmospheric Association to be recorded.
5: EF0- 40-73 mph (could damage chimneys, break tree branches) EF1- 74-112 mph (mobile homes overturned, cars pushed off roads, peels surface off roofs) EF2- 113-157 mph (mobile homes demolished, large trees snapped or uprooted, roofs torn off of frame houses) EF3- 158-206 mph (trains overturned, roofs and possibly walls torn off of well-built houses) EF4- 207-260 mph (well-built houses leveled, structures with poor foundation can be thrown some distance) EF5- 261-318 mph (strongly-built homes pulled off of foundation and carried large distances, cars flying through air, even concrete structures reinforced by steel could have considerable damage done)
6: There is no specific name for a scientist who studies tornadoes, but a scientist that follows storms is called a meteorologist. Meteorologists use the Doppler radars you saw earlier. To be a meteorologist, you need an education with certain courses, like in high school, you would start with physics, chemistry, and Earth science. In college, you could pursue a degree in meteorology. Many colleges have special classes to take to get here.
7: The meteorologist here is Pete Delkus. He is using a Doppler radar as you can see in the background. The rotating red circles mean a tornado is there. This radar was taken on the day all these tornadoes hit.
8: Tornadoes can be very devastating disasters. Land and trees can be torn up and bunnies and squirrels could lose their homes. Humans can lose their houses too. Ben Blackshear (Lancaster) took 15 years remodeling his home. It was gone n 15 seconds. This all depends on the tornadoes strength. These tornadoes happened in Tornado Alley, a large area in the United States where tornadoes are the most frequent. This happens because this is the area when the warm, moist air from the Gulf of Mexico meets cool, dry air from the Rocky Mountains.
9: On April 3, 2012, 20 people were injured, but luckily no one was hurt. The damage was greatly spread throughout North Texas. Homes and schools were destroyed by snapped trees and wind. Debris littered the streets such as lampposts, wood, and bricks. The schools were soon back up and running, but the homes are still under construction. The cities have to pay for all the home and school damage done by the tornadoes. | The Federal Emergency Management Agency (FEMA) has a mission "to support our citizens and first responders to ensure that as a nation we work together to build, sustain, and improve our capability to prepare for, protect against, respond to, recover from, and mitigate all hazards." They have over 7,000 volunteers helping disaster victims throughout the country recover after natural disasters strike.
