Climate change can affect the strength of tornadoes, at present or in future, according to a new study by the Florida State University.

"We may be less threatened by tornadoes on a day-to-day basis, but when they do come, they come like there's no tomorrow", said study author and geography Professor James Elsner in a news release.

However, tornadoes are occurring for less days in a year but they are occurring at a greater density and strength than ever before, according to the Researchers from Florida State University.

Elsner and his co-authors Svetoslava Elsner and Thomas Jagger studied tornadoes of EF-1 and stronger in geographic clusters and the density within these clusters. It is essential to be aware of weather destruction as it might get worse if the climate continues to warm, according to the study.

According to Elsner, many researchers have brushed aside the impact that climate change has on tornadoes because there was no distinct pattern in the number of tornado days per year. For example in 1971, 187 tornado days were reported and in 2013, only 79 tornado days were reported. As such, the number of tornado days witnessed a decline.

It is essential for forecasters and the public to know about this. It is the issue of making sure that the public is aware if there is a higher risk of a storm; there can also be many storms in a day, according to Elsner.

The United States has advance technology and warning systems. The occurrence of tornadoes is more in Unites States than in any other country. In 2011, tornado season had about 1,700 storms and over 550 people were killed.

There have been 189 storms with a death of about 43 so far in 2014, according to the NOAA/National Weather Service Storm Prediction Center.
