  1. Air Masses and Fronts Mrs. Wharton’s Science Class

  2. Air MAss • Huge body of air that has similar temperature, humidity and air pressure • Scientists classify air masses by TEMPERATURE AND HUMIDITY

  3. Tropical v Polar • Tropical ( warm) air masses- form in the tropics and have LOW air pressure. • Polar (cold) air masses- form north of 50 degrees north latitude, and south of 50 degrees south latitude. Have HIGH air pressure.

  4. Maritime V Continental • Maritime- air masses that occur over water. Are HUMID. • Continental- air masses that occur over land. Are DRY.

  5. Front • When air masses meet, and do not mix a front is formed. • When air masses meet at a front, the collision causes storms and changeable weather.

  6. Cold Front • Moves quickly under a warm front. • Brings cold, dry air.

  7. Warm front • When warm air moves over cold air • Move slowly and bring warm, humid air.

  8. Stationary front • Forms when cold and warm air masses meet but neither one has enough force to move the other. • It may bring many days of clouds and precipitation.

  9. Occluded front • Forms when a warm air mass is caught between two cooler air masses. • Warm air is cut off from the ground. • May cause clouds and precipitation.

  10. Cyclone • A swirling center of low pressure • CYCLONES AND DECREASING AIR PRESSURE ARE ASSOCIATED WITH STORMS AND PRECIPITATION. • Anticyclone- are HIGH pressure centers of dry air.
