A vortex, when we are taking about tornadoes is the centre of the tornado. This is where the rapid movement of the air in the tornado is its strongest as there is the most force in this area. As the air has less of a distance to travel to make a full rotation, the speed of the vortex is a lot stronger than the outer areas of the tornado.
You can look at a vortex and how it moves by making your own tornado and you will be able to see how it works. This is how you do it:
First of all, you need to take two bottles and take the labels, lids and any other plastic that may be around the neck off the bottle off.
You then need to fill one of the bottles between half way and two thirds of the way full with water. Put sand in the water to see more clearly how it moves.
You then turn the empty bottle upside down so that the bottles are neck to neck and attach them with tornado tube. These tornado tubes are easy to use and help to prevent leaks but you can also use tape instead and this is just as good. Using tape, you have to make sure that this does not let the water out so you may need to use quite a lot.
Once they are attached you can turn the bottles upside down, a bit like an egg timer, and your tornado will begin.
The reason for getting the tornado to work in the bottles is the displacement of air when the water flows through the small area in the neck of the bottles. This rush of water and the displacement of the air produce the tornado.
