Presentation Transcript

  1. WINDS

  2. DIFFERENCES IN AIR PRESSURE UNEQUAL HEATING OF AIR

  3. LOCALWINDS LAND BREEZE SEA BREEZE MONSOON

  4. MONSOONS SEASONAL WINDS CARRIES WARM MOIST AIR

  5. GLOBAL WINDS UNEQUAL HEATING EQUALS GLOBAL PATTERN OF AIR CIRCULATION

  6. CORIOLIS EFFECT SHIFT IN WIND DIRECTION DUE TO EARTH’S ROTATION

  7. 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.

  8. Responsible for triggering the initial movement of air.

  9. DOLDRUMS CALM SURFACE WINDS AT EQUATOR (0 degrees latitude)

  10. TRADE WINDS AIR MOVING BACK TO THE EQUATOR FORMING A BELT OF WARM, STEADY WINDS

  11. HORSE LATITUDES 30 degrees North and South of Equator Warm air cools and sink; clear skies; winds are calm

  12. PREVAILING WESTERLIES 40-60 degrees Latitude (West to East) Strong Winds

  13. POLAR EASTERLIES COLDBUT WEAK WINDS EAST TO WEST

  14. JETSTREAMS “rivers of air" ABOVE 12 KMS 180-350 Km/Hr (speed)
