Presentation Transcript

  1. LAND BREEZE • OCCURS AS A LOW PRESSURE SYSTEM DEVELOPS OVER WATER AT NIGHT DUE TO SPECIFIC HEAT DIFFERENCES. GOES FROM THE LAND OUT TO THE WATER

  2. SEA BREEZE • OCCURS AS LOW PRESSURE AREA DEVELOPS OVER LAND DURING HEAT OF DAY. AIR FLOWS FROM OCEAN TO LAND BRINGING IN COOLING WINDS.

  3. KATABATIC WIND • COLD DRY MOUNTAIN WIND • ALSO KNOWN AS MISTRAL & BORA • CAN CAUSE EXTREMELY COLD TEMPERATURES IN A RELATIVELY SHORT PERIOD OF TIME.

  4. CHINOOK WINDS • WARM AND DRY MOUNTAIN WIND BRINGING RAPID TEMPERATURE INCREASES • ALSO KNOWN AS ZONDA, FOEHN, & SANTA ANA

  5. MONSOON • SEASONAL REVERSAL OF WIND • DRY MONSOON OCCURS IN WINTER WITH LOW PRESSURE OVER WATER • WET MONSOON OCCURS IN SUMMER WITH LOW PRESSURE OVER LAND

  6. AIR MASSES & FRONTS • Chapter 19

  7. AIR MASS • A LARGE BODY OF AIR THAT IS CHARACTERIZED BY THE SAMENESS OF TEMPERATURE & HUMIDITY

  8. SOURCE REGION • THE AREA WHERE AN AIR MASS ACQUIRES ITS PROPERTIES OF TEMPERATURE AND MOISTURE • CONTINENTAL – LAND [DRY] • MARITIME OR MARINE – WATER [MOIST]

  9. AIR MASSES

  10. FRONTS • BOUNDARIES THAT SEPARATE AIR MASSES OF DIFFERENT DENSITIES • WARM – OVER RUNNING • COLD • OCCLUDED - PINCHING • STATIONARY

  11. WARM FRONT

  12. COLD FRONT

  13. OCCLUDED

  14. STATIONARY FRONT

  15. MID-LATITUDE CYCLONES • PRIMARY WEATHER PRODUCERS IN MID- LATITUDES [30 –60 DEGREES] • LARGE CENTERS OF LOW PRESSURE THAT GENERALLY TRAVEL FROM WEST TO EAST LASTING FROM A FEW DAYS TO MORE THAN A WEEK • COUNTERCLOCKWISE MOTION
