Week 2 of Weather

 This week we talked about wind. When air is moving vertically, it’s called an updraft. Air motion is caused by 3 forces. The first force is the pressure Granite Force also known as PGF. This is when high pressure areas force the air into low pressure areas. The second force is the Coriolis Force this is when the rotation of the Earth causes air to turn. In the Northern hemisphere hurricanes spin in one direction and in the southern hemisphere they spin in the opposite direction. And last but not least the third force is friction which slows the flow of wind.
