Join the community patreon.com/itsokaytobesmart↓↓↓ More info and sources below ↓↓↓Hurricanes, typhoons, and tropical cyclones are Earth’s most powerful storms, capable of unleashing destruction and death on coastal areas worldwide. As climate change warms Earth’s oceans, we face more risk of storms rapidly intensifying into category 5, sometimes in less than a single day. Being able to predict these rapidly intensifying storms will save lives, but studying hurricanes in detail is difficult and dangerous. So in order to improve our understanding of hurricanes, scientists have built a machine that can create hurricane conditions indoors. #weather #hurricanes Filmed at the Alfred C.
