![]() ![]() “The data that I’ve seen has persuaded me that we are in this experiment and living it right now,” Ashley said in an interview three days before the EF-4 tornado killed more than 20 people in Mississippi on Friday. But Ashley said that stormier future seems like it’s already here. The study used computer simulations to predict what will happen by the end of the century with different levels of global carbon pollution levels. Supercells spawned the 2013 Moore, Oklahoma, tornado that killed 51 people, the 2011 Joplin, Missouri, tornado outbreak that killed 161 people and the 2011 super outbreak that killed more than 320 people in Alabama, Mississippi and Tennessee, the Mid-South. Tall, anvil-shaped and sky-filling, supercells have a rotating powerful updraft of wind and can last for hours. Supercells are nature’s ultimate storms, so-called “Finger of God” whoppers that are “the dominant producers of significant tornadoes and hail,” said lead author Walker Ashley, a professor of meteorology and disaster geography at Northern Illinois University. That includes Rolling Fork, where study authors project an increase of one supercell a year by the year 2100. But in certain areas in the South the increase is much higher. The study in the Bulletin of the American Meteorological Society predicts a nationwide 6.6% increase in supercells and a 25.8% jump in the area and time the strongest supercells twist and tear over land under a scenario of moderate levels of future warming by the end of the century. ![]() And the season will start a month earlier than it used to. But it fits that projected and more dangerous pattern, including more nighttime strikes in a southern region with more people, poverty and vulnerable housing than where storms hit last century. The supercell storm that devastated Rolling Fork, Mississippi is a single event that can’t be connected to climate change. It does not store any personal data.(AP) - America will probably get more killer tornado- and hail-spawning supercells as the world warms, according to a new study that also warns the lethal storms will edge eastward to strike more frequently in the more populous Southern states, like Alabama, Mississippi and Tennessee.
