It represents the tropopause  Can predict which have a higher aptitude in the season  Summer time, exchange of energy between high and low latitudes are different than winter  Position of Polar Jet Stream over North America and Atlantic Ocean in Winter (Horizontal Shear: creates significant clockwise movement of air)  Interaction between polar air and subtropics air include: pressure gradients, and second have to do with an interaction northeasterlies, and westerlies air o Causing disturbance along the border, colder air moving opposite of warmer air creating horizontal stress TWO DRIVERS: Latitudinal pressure gradients, Cyclogenisis  Meridional flow, vortex of wind being created by rotation of cold and warm air creating high pressure systems in north and low in south, reason why exchange of power systems o Good process f
