Editing Tornado Box (section)

== Why This Works ==

''Meteorology'' is the study of the weather and weather systems, like hurricanes, tornadoes and cyclones. Tornadoes and cyclones are powerful spinning winds that can topple houses and send trees flying. In order for them to form, however, there are a few things that need to happen. First, there needs to be '''''warm, moist air'''''. Warm, moist air is ''less dense'' than dry air, so it will want to rise above the air around it. This is part of the reason why you will see a shelf cloud in front of a storm, or a wall cloud form inside of a storm; that area is an area with a strong updraft, due to the warm, humid air rising above the air around it. Second, there needs to be a cross breeze. A '''''cross breeze''''' means that there is air blowing in more than one direction, and these breezes are colliding with each other. You may haven already seen what a small cross breeze can do; If you have ever seen a little "leaf tornado" or a small whirlwind, those are created by two breezes colliding. Lastly, these two things need to happen close to the same spot. If these conditions are all met, you will see a cyclone form!

For our tornado box, you can adjust the size of the cyclone by changing how big the slots are. if the slots are wide open, then the cross breeze will be weak, so the cyclone might not form, or if it does then it will be really wide and slow spinning. If the slots are mostly closed, then the cross breeze will be strong, and you should see a thin and fast spinning cyclone!
