  • Great walls could eliminate major tornado threat in Tornado Alley, expert says
    on June 23, 2014 at 4:03 pm

    Can we eliminate major tornadoes in Tornado Alley? Devastating tornadoes over there start from violent clashes between northbound warm wind and southbound cold wind. If engineers built three east-west great walls, 300 meters high and 50 meters wide, one in North Dakota, one passing Oklahoma and one in Texas, such barriers would weaken such air mass clashes and diminish major tornado threat, according to one expert. […]

  • 2013 Tornadoes: Numbers Low, Destruction High
    on May 28, 2014 at 7:04 pm

  • Small changes could save structures, lives during tornadoes: Safe rooms, quality garage doors...
    on May 1, 2014 at 5:25 pm

    Surviving a tornado in a wood-frame residential home is enhanced by an intact roof and standing walls, but light-weight garage doors can be the weak link to allowing high winds and pressure changes into a home that can lead to the removal of the roof and collapsed walls, according to a study of damage left behind by a powerful tornado in Moore, Oklahoma, in 2013. […]

  • Multiple consecutive days of tornado activity spawn worst events
    on April 30, 2014 at 6:30 pm

    Significant tornado outbreaks and especially strong tornadoes are more likely occur within periods of activity lasting three or more days, according to a tornado expert. An examination of 30 years of US weather records found that an outbreak of 20 or more reported tornadoes had a 74 percent probability of occurring during a period of tornado activity lasting three or more days. During those same periods, a tornado rated three or higher on the Enhanced Fujita scale had a 60 percent probability of hitting. […]
