Sorry, no winner this week. Here is my weekly weather quiz question for the last time. When tornadoes strike they have very strong winds. It is not possible to actually measure the winds created by tornadoes, so Dr. T. Ted Fujita created a scale of wind speeds based on the damage caused by the tornado. As of 2007  his designations have been changed. For example a tornado was listed as an F4 and now might be designated as an EF4. What does the “E” stand for and what does it mean? The Enhanced Fujita Scale (EF Scale) rates the strength of tornadoes in the United States based on the damage they cause. Implemented in place of the Fujita scale introduced in 1971 by Ted Fujita, it began operational use on February 1, 2007. The scale has the same basic design as the original Fujita scale: six categories from zero to five representing increasing degrees of damage. It was revised to reflect better examinations of tornado damage surveys, so as to align wind speeds more closely with associated storm damage. Better standardizing and elucidating what was previously subjective and ambiguous, it also adds more types of structures, vegetation, expands degrees of damage, and better accounts for variables such as differences in construction quality. The new scale was publicly unveiled by the National Weather Service at a conference of the American Meteorological Society in Atlanta on February 2, 2006. It was developed from 2000 to 2004 by the Fujita Scale Enhancement Project of the Wind Science and Engineering Research Center at Texas Tech University, which brought together dozens of expert meteorologists and civil engineers in addition to its own resources. To see the Fujita scale and the Enhanced Fujita Scale go to: http://www.ncdc.noaa.gov/oa/satellite/satelliteseye/educational/fujita.html

I’ll have another weekly weather quiz question for you next Monday. Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count.

Sorry, no winner this week. Here is my weekly weather quiz question for the last time. When tornadoes strike they have very strong winds. It is not possible to actually measure the winds created by tornadoes, so Dr. T. Ted Fujita created a scale of wind speeds based on the damage caused by the tornado. As of 2007  his designations have been changed. For example a tornado was listed as an F4 and now might be designated as an EF4. What does the “E” stand for and what does it mean? The Enhanced Fujita Scale (EF Scale) rates the strength of tornadoes in the United States based on the damage they cause. Implemented in place of the Fujita scale introduced in 1971 by Ted Fujita, it began operational use on February 1, 2007. The scale has the same basic design as the original Fujita scale: six categories from zero to five representing increasing degrees of damage. It was revised to reflect better examinations of tornado damage surveys, so as to align wind speeds more closely with associated storm damage. Better standardizing and elucidating what was previously subjective and ambiguous, it also adds more types of structures, vegetation, expands degrees of damage, and better accounts for variables such as differences in construction quality. The new scale was publicly unveiled by the National Weather Service at a conference of the American Meteorological Society in Atlanta on February 2, 2006. It was developed from 2000 to 2004 by the Fujita Scale Enhancement Project of the Wind Science and Engineering Research Center at Texas Tech University, which brought together dozens of expert meteorologists and civil engineers in addition to its own resources. To see the Fujita scale and the Enhanced Fujita Scale go to: http://www.ncdc.noaa.gov/oa/satellite/satelliteseye/educational/fujita.html

I’ll have another weekly weather quiz question for you next Monday. Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count.
