About the Author
There are many different signs of a tornado. By watching out for these things, you can be better prepared for one!
Doppler radar can see not only the precipitation in a thunderstorm, but motion of the precipitation along the radar beam. In other words, it can measure how fast rain or hail is moving toward or away from the radar. Make sure that when a storm occurs, you are checking your weather stations Doppler radar.
Watch out for debris in the air in your neighborhood or outside of where you are located. Debris in the air is a warning sign of a tornado coming.
If it starts raining outside, watch for hail. Tornados follow the coming of hail. Or if a hailstorm is followed by a dead calm, that is also a sign of the tornado drawing near.
If you hear a noise that sounds like a dull roar, or the sound of a train coming, that may be the sign of a tornado rapidly approaching.
Two different types!
There are many different types of tornadoes! Today we are going to explore two of these types: waterspout and Multivortex tornadoes!
What to do in a tornado
Whether you are in a building, a car, or in your own house, there are many things you need to do to ensure your safety in a tornado!
When you are in a house, make sure that you go down to your basement, or to an area that is enclosed with hardly any windows. When you are there, get away from any breakable items.
In a building
When in a school or business building, make sure that you stay away from all windows. Get under a sturdy table or chair and get into a crouching position.
In a Car
When inside of a car, and a tornado is spotted, the best thing to do is park the car safely and get out. Go into a lower ditch or inside a safe building. Cars can be easily flipped over by high winds.

A waterspout is a tornado that occurs over water, usually meaning non-super cell tornadoes over water. Waterspouts are common along the southeast U.S. coast and especially off southern Florida and the Keys. They can happen over seas, bays and lakes worldwide. They are smaller and weaker than the most intense Great Plains tornadoes, but still can be quite dangerous. Waterspouts can overturn small boats, damage ships, do significant damage when hitting land, and kill people.
Multivortex tornadoes contain two or more small, intense sub vortices orbiting the center of the larger tornado circulation. When a tornado doesn't contain too much dust and debris, they can be very visible. These vortices may form and die within a few seconds, sometimes appearing to train through the same part of the tornado one after another. They can happen in all sorts of tornado sizes.
What is a Tornado?
A tornado is defined as: a violently rotating column of air, pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud.
How is a tornado formed? Tornadoes can form out of many kinds of storms, but the type most likely to produce tornadoes is the super cell . A super cell has an area of rotation within the storm called a mesocyclone that can create a tornado. The storm itself can rotate when winds at different levels of the atmosphere come from different directions. If the winds are lined up just right, with just enough strength, the storm turns like a top. Air circulations within the storm combined with a strong updraft contribute to tornado formation. Quit
A tornado is only a tornado if it's in contact with the ground. Otherwise, it's a funnel . Some tornadoes don't have a visible funnel, but if debris is visible at the ground, it is considered a tornado. Because big storms can suck up dust or kick up dust even when there's no tornado, sometimes they can be confusing to observers. If there is rotation in the cloud above the dust, then it may very well be a tornado.
