Washington: A change in climate may be causing more and deadlier tornadoes that are hitting the US, as revealed by a new study.
The climate change may be playing as a key role in the strength and frequency of tornadoes, according to a research by a Florida State University geography professor. Tornadoes are forming at a greater density and strength than ever before, but they are forming for fewer days per year.
Tornadoes are being experienced more in the United States than any other country. They still remain a hazard to residents in strom-prone areas, despite advances in technology and warning systems.
According to the NOAA/National Weather Service Storm Prediction Center, the 2011 tornado season had nearly 1,700 storms and killed more than 550 people. While in 2014,there have been 189 storms with a death toll of 43.
Many researchers dismissed the impact of climate change on tornadoes because there was no distinct pattern in the number of tornado days per year, as said in the past by James Elser.
In 1971, there were 187 tornado days, but in 2013 there were only 79 days with tornadoes.
The study was published in the journal Climate Dynamics.
