+ the polar high, polar easterlies, and polar front. + the bermuda and pacific highs + the canadian and siberian highs. + the aleutian, icelandic, and southern hemisphere upper mid-latitude lows (polar fronts) Recall: heat is transported from the equator to the poles - how?- diagram c in lecture 6. Around the equator = (itcz) inter-tropical convergence zone. Intense heating causes air to rise, leading to little horizontal motion at times. Down dropt the breeze, the sails dropt down, We stuck, nor breath nor motion; as idle as a painted ship. At high, winds are calm referred to as horse latitudes. + cooled air skins at 30 degrees n & s. The 2 convection cells that form from the itcz and the n&s subtropical pressure belts. Predictable winds form near the surface within the hadley cells trade winds. Cooled air sinks at 30 degrees n&s **draw diagram.
