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

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

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

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

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

AIR MASSES & FRONTS Chapter 19

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

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

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

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
