Hurricanes are known for the damage they can cause on land. But the massive, swirling storms can also cause big changes offshore. A recent study by scientists at the University of California San Diego found that hurricanes and typhoons (as these storms are known in the western Pacific) create underwater waves that push warm water deep into the ocean. This heat remains trapped long after the storm has passed. Moving ocean currents can then transport the heat around the globe, affecting climate and warming the habitat of marine animals in other parts of the world.
