Transcript of Tornado Presentation
Tornado Alley Tornado Alley is a place where more than the average amount of tornadoes occur. This place is located in the United States between the Rocky Mountains and the Appalachian Mountains. Between these areas, Texas is the top ranking spot for tornadoes; Kansas and Oklahoma come in very close. The reason that this location is the most popular for tornadoes would be because the colder, dry air from Canada and the Rocky Mountains come in direct contact with the warmer, humid air from the Gulf of Mexico and the dry, hotter air from the Sonoran Desert. With all of these things taking place, it creates an unstable atmosphere, as well as heavy precipitation and strong thunderstorms, therefore creating tornadoes. Worst Tornado in Tornado Alley The worst tornado that has ever occurred in Tornado Alley took place in Greensburg, Kansas on March 4th, 2007. This tornado was 1.7 miles wide and was an F5 on the Enhanced Fujita Scale. It was a part of a storm front that went directly through Kansas, causing several different tornadoes in Illinois, Oklahoma, South Dakota, and Nebraska. As you know, the speed of a tornado may vary, and the wind speeds of this one were about 200 miles per hour every three seconds, and traveled at the speed of 22 miles per hour. This tornado that struck Greensburg, Kansas was moving so fast, that the people were only given 20-26 minutes of warning time in order to head to safety and become prepared for what was going to be the biggest storm that has ever hit them. After this storm hit, it flattened out most of Greensburg and 95% of the town was destroyed, building were no longer standing and all forms of vegetation, including trees, were destroyed. Many people were injured and more than eleven people had passed away. This whole storm caused a lot of distress and emotion from people who lost their homes, friends, and family members. Short Term Preparation -Flashlight
-Battery-powered radio/self-powered radio
-First aid kit
-Non-perishable food Long Term Preparation
-Make sure you know all the procedures that you and your family will have to take.
-Attend your community meetings and decide with your community what to do in the event of a disaster.
You could also attend classes that teach you CPR and other important first aid that may come in handy if a tornado occurs in your area.
-Build a storm shelter. This storm shelter should include blankets, water, non-perishable food items battery powered radio, and a first aid kit.
-Making a plan for your family to follow and practice would also be a great idea to prepare everyone that you care about. After the Storm After the storm passes, several things are done. In many cases, bulldozers are brought into the picture to get rid of the debris. After the storm, you should never use your electricity or light candles because there could be gas leaks. Also, keeping away from downed power lines and report it to the utility company. If you see someone injured help them out as best as you could, without moving them because the Red Cross will be on its way to help them, so you have to make sure that you are out of the way. Keep an eye out for unstable beams, cracks, or other kinds of damage and have yourself and other dress in heavy clothing and shoes. Prediction Tornadoes are very hard to predict because there is nothing to measure it exactly. The only way to track these natural disasters would be to track wind currents. You can tell if a tornado has a chance of forming if two wind currents are going towards each other, forming the potential risk of creating an unstable atmosphere. But there are many signs of a tornado you should know, besides the wind currents... This includes: -strong, persistent rotation around the cloud base.
-debris or dust around the cloud base.
-clouds moving very rapidly.
-hail or heavy rain followed by an instant calm. What Should You Do? IF..
You don't have a storm shelter?
-Get to the lowest level of your house. if you do not have a basement, then hide under a stairwell, in an interior hallway with no windows, or in a bath tub with a mattress on top of you to avoid falling debris. You are in a mobile home?
-Get out. Even if you think it is safe and tied down, you need to get out. You are in a public place such as a shopping mall?
-Watch for what others are doing. As soon as you can, make it to the nearest bathroom, or storage room. Just make sure that you stay away from windows! You are outside?
-If possible, get inside. But if not, then lay flat and face down, making sure that you cover your head.
