Dragon hoses chase each other in America

Two cannons appeared at the same time on American waters last week and a scientist captured this amazing scene.

Tim Osborn, a researcher from the US National Oceanic and Atmospheric Administration (NOAA) discovered dual cannons when he arrived at Grand Isle in the Gulf of Mexico and near the state of Louisiana on 9 May. They formed at the edge of a strong storm, Livescience said.

"Everyone can clearly see their formation in the sky , " Osborn said.

The two cannons formed on the clouds in the north of Grand Isle and their altitude gradually decreased until they reached the sea surface. Water splashed as the pair of dragons moved towards the island.

Compared to the cannons that Osborn had observed, the pair of dragonheads near Grand Isle had many special features."Their size increases, they move in a sticking pattern and the time lasts about 10 to 15 minutes - much longer than other cannons," Osborn explained.

The underwater water cannons usually only exist for a very short time and "fly" into the sky. They are usually smaller and have less destructive power than those formed on clouds. The power of the dragon-shaped hose in the clouds is almost unchanged if they move to the land. So they can destroy what they meet.

One of the two cannons in Osborn's image moved into the island. It broke the power line, flipped the roof of a house and damaged seven other houses, before moving to the Gulf of Mexico. The US National Weather Agency said the area suffered the devastation of a water cannon about 400m long and 122m wide.
