When Water Starts Spinning
Few events look as cool as a waterspout stretching between a cloud and the water below. Often described as the ocean’s tornado, this rotating column of air and mist can appear over seas, lakes, and even rivers. Though there’s nothing wrong with admiring one from a safe distance, the science behind that funnel is every bit as fascinating as the spectacle itself!
1. Not Every Waterspout is a Tornado
Meteorologists divide waterspouts into fair-weather and tornadic varieties. Tornadic waterspouts develop from severe thunderstorms and are more closely related to land tornadoes, while fair-weather versions usually form beneath growing cumulus clouds in calmer conditions.
2. Some of Them Build From the Water Up
A tornadic waterspout descends from a thunderstorm, but a fair-weather waterspout doesn’t. Those begin near the water’s surface and develop upward toward the cloud. By the time you can clearly see its funnel, it may actually be close to maturity.
3. The Funnel Isn’t Full of Ocean Water
Despite appearances—and its name—a waterspout doesn’t lift a solid tube of seawater into the sky. What you’re mostly seeing is a rotating column of air that’s only made visible by condensed moisture. So, don’t worry, it isn’t draining the ocean one spinning funnel at a time.
4. They Aren’t Limited to the Ocean
The name may bring tropical coastlines to mind, but waterspouts have also been observed over rivers and large lakes. Keep an eye out; they’re regularly seen over the Great Lakes, while the Florida Keys are considered one of the world’s busiest locations for sightings.
5. They Can Become Land Tornadoes
Don’t just assume that a waterspout will vanish when it reaches the shore. Some can move onto land, and the National Weather Service may even issue a tornado warning if the danger is imminent enough. The transformation is impressive, sure, but it’s also your cue to stop watching and find shelter.
