DIFFERENCES IN AIR PRESSURE UNEQUAL HEATING OF AIR
LOCALWINDS LAND BREEZE SEA BREEZE MONSOON
MONSOONS SEASONAL WINDS CARRIES WARM MOIST AIR
GLOBAL WINDS UNEQUAL HEATING EQUALS GLOBAL PATTERN OF AIR CIRCULATION
CORIOLIS EFFECT SHIFT IN WIND DIRECTION DUE TO EARTH’S ROTATION
As air moves from high to low pressure in the northern hemisphere, it is deflected to the right by the Coriolis force. In the southern hemisphere, air moving from high to low pressure is deflected to the left by the Coriolis force.
DOLDRUMS CALM SURFACE WINDS AT EQUATOR (0 degrees latitude)
TRADE WINDS AIR MOVING BACK TO THE EQUATOR FORMING A BELT OF WARM, STEADY WINDS
HORSE LATITUDES 30 degrees North and South of Equator Warm air cools and sink; clear skies; winds are calm
PREVAILING WESTERLIES 40-60 degrees Latitude (West to East) Strong Winds
POLAR EASTERLIES COLDBUT WEAK WINDS EAST TO WEST
JETSTREAMS “rivers of air" ABOVE 12 KMS 180-350 Km/Hr (speed)
