Document Summary
Geog 2050 test 3 notes this will be the hardest exam of the entire course. March 12: - (chapter 6) air pressure, mercury barometer, aneroid barometer, wind, anemometer, wind vane, Pinatubo eruption in hong kong 1992 same bright colors: atmospheric circulation, mt. Pinatubo erupts in june 1991 2nd largest in 20th century with a vei of 6: satellites track where all of the ash and soot travels it increases and almost encircles the whole. In the absence of other forces, air moves from high pressure to low pressure via the pressure gradient force: typically this occurs over shorter differences c. = 20 mbar / 2070 miles = about 0. 01 mbar/mile this small slope means smaller/slower winds: ex: (1020 mbar 1000 mbar) / (35 degrees 45 degrees) 20 mbar / (10 degrees x 69 miles) = 20 mbar/690 miles = about 0. 03 mbar/mile this steeper slope means faster winds.
