Waterspouts that are not associated with a rotating updraft of a supercell thunderstorm are known as "non-tornadic" or "fair-weather" waterspouts. By far the most common type of waterspout, these occur in coastal waters and are associated with dark, flat-bottomed, developing convective cumulus towers.

2024年6月16日 · Tornadic waterspouts are tornadoes that form over water, or move from land to water. They have the same characteristics as a land tornado. They are associated with severe thunderstorms, and are often accompanied by high winds and seas, large hail, and frequent dangerous lightning.

2024年4月26日 · A tornado over an ocean, lake – or even a river – is considered to be a waterspout. Waterspouts are typically weaker than most tornadoes. And they’re usually short-lived.

2021年4月27日 · The big difference between this and a tornado is that the tornado starts in the clouds and works its way down while a waterspout starts on the surface of the water and goes up. According to the National Weather Service , the funnel goes through five stages, starting with a dark spot on the water, followed by a spiral pattern, then a spray ring ...

Tornadic waterspouts are simply tornadoes that form over water, or move from land to water. They have the same characteristics as a land tornado. They are associated with severe thunderstorms, and are often accompanied by high winds and seas, large hail, and frequent dangerous lightning.

Waterspouts are almost always produced by a swiftly growing cumulus cloud. They may assume many shapes and often occur in a series, called a waterspout family, produced by the same upward-moving air current. Waterspouts are closely related to other atmospheric phenomena such as tornadoes, whirlwinds, and fire storms.

Waterspouts and tornadoes are both rotating columns of air, but they differ in their location and formation. Waterspouts form over bodies of water, while tornadoes typically form over land. Waterspouts are also typically weaker than tornadoes.

2024年8月21日 · Are waterspouts essentially tornadoes on water? While waterspouts and tornadoes both involve rotating columns of air, there are important differences in how they form, their environment and...

2024年2月15日 · Tornadic waterspouts begin as true tornadoes and are influenced by winds associated with severe thunderstorms. As the air rises, it rotates on a vertical axis. This makes the tornadic waterspouts...

2023年6月9日 · Waterspouts are tornado-like columns of water and air that form over water, or have moved to water after forming on land [source: NOAA]. They're accompanied by tornado conditions, too — huge hail, stormy conditions and dangerous lightning. That means the usual tornado warnings apply. Stay away from waterspouts if you see them.
