Tornadoes

Tornadoes are violently rotating clouds of air that come into contact with the ground. Tornadoes develop from a special type of cloud called a funnel cloud and will develop a swirling tail that will get closer and closer to the ground The spiraling wids will rotate in speeds over 100 mph and cause vast destruction upon reaching the ground. Most tornadoes are associated with thunderstorms and the immediate oncoming of a cold front during warmer months of the season.
Tornadoes frequently occur in the Midwestern United States in what is commonly referred to as Tornado Alley. Tornado Alley stretches across the midwest ranging from Oklahoma to Illinois.
On the map above you can see that Tornado Alley stretches across the midwest and is pretty much relocated to this area. It is very important for us to understand as much information as we can about this natural disaster as we are living in this region.
Tornado season is generally from late spring to summer as this is prime conditions for the thunderstorms needed to produce this devastating disaster.
Oklahoma 2013:
The last major tornado to affect the United States was in Oklahoma in the spring of 2013. The tornado was a registered F-5 and did damage across a wide area. There were approximately 50 deaths while over 350 were injured. The estimated amound of damage was around 2 billion dollars. Located below are a couple of links to articles and pictures of the devastating earthquake that swept through Oklahoma on this late spring day. The stories from this national disaster are extremely tragic and let's us know that tornadoes are nothing to be messed with.
The devastation in Moore, Oklahoma is still being felt today as many people's lives changed forever that day. Tornadoes truly are terrible disasters to occur and sometimes it takes a very long time for communities to heal.
We rely heavily on the information that meteorologists present to us. The weathermen are going to utilize a device called a Doppler Radar. They utilize this radar to detect the ways the weather is moving and general information about the current weather coniditions. The Doppler Radar information then is presented to the public of the general area and it can be placed under Tornado Warning or Watch. The difference between a watch and a warning is that during a warning the piece of weather is actively occurring.
There is also a group of people who are chasing these storms to try to capture photos that will better understand how tornadoes work. The chases may use homemad device that are sucked up and released within a tornado to get a better idea of the internal conditions within a tornado.
