With an average energy of roughly 1 million pounds of TNT, tornados are one of nature’s most powerful phenomena. And while atmospheric scientists know a great deal about tornados, such as the conditions in which they are most likely to form, no one yet understands exactly what makes a tornado or how to accurately predict their creation.
