A hurricane location and time is usually predictable, but the problem is that when it started it cannot be stopped. So scientists try to find a way to block them in origin - warm ocean surface, as without hot water a hurricane cannot be formed. The warm layer is very thin, while under it is much colder water. One interesting solution I read about is an inner tube with a skirt, a large floating ring, anywhere from thirty to three hundred feet across, with a long flexible cylinder affixed to the inside. Now warm waves splashes over the top, the water level inside the ring rises until it is higher than the surrounding ocean. It will push the warm surface water down into the long plastic cylinder, ultimately flushing it out at the bottom, far beneath the surface, which inevitably lowers the ocean’s surface temperature and thus prevent hurricanes.
