Tornado over water or waterspout as is also known, is a very intense vortex in the form of a column, phenomenon with a funnel-shape, which occurs over a body of water, connected to a cumuliform cloud. Tornadoes at sea may be very dangerous and they are usually accompanied with thunderstorms.
Only seafarers (the blessed ones only) may have the chance to see such a rare prodigy at sea. There is an amazing video of tornado at sea below, captured by Capt. Sarakatsianos Chrysovalantou with his camera, caught from the very beginning. The waterspout was captured in Bohai Sea in China while Capt. Chrysovalantou passed with his ship along the rare phenomenon.
If you look closely at the end of the video, you can even see another tornado formation in the distance.
Don't miss to watch the video of tornado formation as the ship passes by in Bohai Sea.
