A new study by researchers at the University of Illinois at Urbana-Champaign has found that hills can provide shelter from tornadoes. The study, published in the journal Physics of Fluids, used computer models to simulate the flow of air around hills and found that a region of low pressure can form behind the hill. This region of low pressure can provide shelter from the high winds and debris that are associated with tornadoes.

The study found that the size of the sheltering region depends on the size and shape of the hill. The larger the hill, the larger the sheltering region. The study also found that the sheltering region is most effective when the tornado is approaching the hill from the side.

The researchers say that their findings could help to improve tornado safety. They say that people who live in areas that are prone to tornadoes should consider building hills or other structures that could provide shelter from tornadoes.

The study is the first to use computer models to simulate the flow of air around hills and tornadoes. The researchers say that their findings are a significant step forward in understanding how tornadoes interact with the environment.

Tornadoes are one of the most destructive forces of nature. They can cause widespread damage and loss of life. In the United States, tornadoes kill an average of 70 people each year.

The findings of this study could help to save lives by providing people with a safe place to shelter from tornadoes.
