Now that students have learned about local winds, they will learn about the coriolis force which drives global winds and storm systems.  To do this, students cut out globes and tacked them to a sheet of paper.  When viewed from space, the northern and southern hemispheres rotate counter-clockwise and clockwise, respectively.  To simulate this, students will draw lines on the hemispheres while rotating them the appropriate directions.  After this, students can see that the coriolis effect deflects wind to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

Students are learning about local winds through notes, discussions and problems.  We relate these to the previous topics of convection and our P.O.E.  Here is an example of the problems they have to do.
