The Fujita Scale Is Used to Rate the Intensity of a Tornado by Examining the Damage Caused by the Tornado After It Has Passed Over a Man-Made Structure
The Fujita Scale is used to rate the intensity of a tornado by examining the damage caused by the tornado after it has passed over a man-made structure. The "Percentage of All Tornadoes 1950- 1994" pie chart reveals that the vast majority of tornadoes are either weak or do damage that can only be attributed to a weak tornado. Only a small percentage of tornadoes can be correctly classed as violent. Such a chart became possible only after the acceptance of the Fujita Scale as the official classification system for tornado damage. It is quite possible that an even higher percentage of all tornadoes are weak. Each year the National Weather Service documents about 1000 tornado touchdowns in the United States. There is evidence that 1000 or more additional weak tornadoes may occur each year and go completely undocumented. The "Percentage of Tornado-Related Deaths 1950-1994" pie chart shows that while violent tornadoes are few in number, they cause a very high percentage of tornado-related deaths. The Tornado Project has analyzed data prior to 1950, and found that the percentage of deaths from violent tornadoes was even greater in the past. This is because the death tolls prior to the introduction of the forecasting/awareness programs were enormous: 695 dead(Missouri-Illinois-Indiana, March 18, 1925); 317 dead(Natchez, Mississippi, May 7, 1840);.255 dead(St. Louis, Missouri and East St. Louis, Illinois, May 27, 1896); 216 dead(Tupelo, Mississippi, April 5, 1936); 203 dead(Gainesville, GA, April 6, 1936). In more recent times, no single tornado has killed more than 50 people since 1971. -
Tornado Safety Q & A
TORNADO SAFETY Q & A The Prosper Fire Department Office of Emergency Management’s highest priority is ensuring the safety of all Prosper residents during a state of emergency. A tornado is one of the most violent storms that can rip through an area, striking quickly with little to no warning at all. Because the aftermath of a tornado can be devastating, preparing ahead of time is the best way to ensure you and your family’s safety. Please read the following questions about tornado safety, answered by Prosper Emergency Management Coordinator Kent Bauer. Q: During s evere weather, what does the Prosper Fire Department do? A: We monitor the weather alerts sent out by the National Weather Service. Because we are not meteorologists, we do not interpret any sort of storms or any sort of warnings. Instead, we pass along the information we receive from the National Weather Service to our residents through social media, storm sirens and Smart911 Rave weather warnings. Q: What does a Tornado Watch mean? A: Tornadoes are possible. Remain alert for approaching storms. Watch the sky and stay tuned to NOAA Weather Radio, commercial radio or television for information. Q: What does a Tornado Warning mean? A: A tornado has been sighted or indicated by weather radar and you need to take shelter immediately. Q: What is the reason for setting off the Outdoor Storm Sirens? A: To alert those who are outdoors that there is a tornado or another major storm event headed Prosper’s way, so seek shelter immediately. I f you are outside and you hear the sirens go off, do not call 9-1-1 to ask questions about the warning. -

Temperature Change and Its Effects on the Great Lakes Climate
Temperature Change and its Effects on the Great Lake’s Climate. Ross Ellet Professor: Matthew Huber April 28, 2005 Temperature change and its effects on the Great Lakes climate. The Great Lakes create a very unique sub climate zone that is unlike most areas in the world. The Great Lakes act as a climate moderator. They contain some of the biggest fresh water lakes in the world. This allows temperature moderation to occur. Typically the lakes keep the eastward coastlines more humid. Since there is more humidity, clouds are more frequent. Thus the temperature fluctuation on a daily basis is a little less than areas not affected by the Great Lakes. This in turn affects the precipitation that falls, when it falls, and where it falls. In the winter time the cold air masses blow over the relatively warm water which creates lake-effect snowfall. This is a very important social and economical impact the climate has on the Great Lakes region. So what happens when a climate change occurs in this area? What types of impacts will it have on the Great Lakes region? Will it be any different than those areas directly west of the Great Lakes? Theory and Research Aral Sea In order to understand climate change in the Great Lakes, first one must understand the dynamics of what is already occurring. The Great Lakes is unlike most lakes in the world due to its size, power, and potential to affect climate. However, there is another body of water that is just as significant. The Aral Sea, which is located in Uzbekistan and Kazakhstan, is an important tool to see how much a large body of water affects climate. -

Severe Weather: Thunderstorms and Tornados
Health and Safety Alert January 2020 Severe Weather Watches and Warnings: Thunderstorms and Tornados A severe weather watch alerts people that severe weather is expected or that conditions are favorable for the development of severe weather. A severe weather warning means that severe weather is occurring, imminent, or likely in the location indicated and is a threat to life and property. People in the warning area need to take action immediately. Severe Weather Watches and Warnings are issued by the National Weather Service. When a watch is issued: A watch may be issued hours before a storm. The sky may be sunny when you first hear a severe thunderstorm or tornado watch. After you learn of a watch, check weather information frequently: While watches may be issued before storms form, thunderstorms may be developing when the watch is posted, or thunderstorms may be ongoing and moving into the area. By checking the weather information again, you will be aware of what is going on around you. Options for staying informed about the weather include: • Weather radios • TV news channels • AM/FM radio • Internet • Emergency alerts via phone, e-mail or text When a severe thunderstorm warning is issued: Do not ignore severe thunderstorm warnings! Severe thunderstorm warnings often precede tornado warnings, providing you with extra time to prepare for a dangerous storm. If there is a severe thunderstorm headed your way, you should monitor it closely, especially if a tornado watch is also in effect. Move inside and away from windows. Severe thunderstorms can produce damaging straight- line winds and large hail.
