  1. Weather Symbols and Station Models

  2. Why do we use Symbols? • Less space • Universal language • Why do we use station models • Gives us a small picture of weather in a certain location.

  3. Fronts • Four types • Warm • Cold • Occluded • Stationary • Boundaries where air masses meet

  4. Fronts • Cold Fronts • Cold air forced down • Warm air rising • Fast • Stormy rainy • Cumulonimbus clouds

  5. Fronts • Warm Fronts • Warm air gradually replaces cold air • Slower • Light rain then clear skies • Warmer temps.

  6. Fronts • Occluded • Air mass over taken by cold air mass • Rainy • Cool temps

  7. Fronts • Stationary Fonts • A cold air mass meets a warm air mass and nothing really happends • Weather is like that of a warm front • Light rain • Warm temps • Then clear

  8. Air Masses • Low Pressure • Weather is usually rainy, cloudy • Air pressure is around 29.ish

  9. Air Masses • High Pressure • Weather is usually sunny clear and dry

  10. Station Models Air Pressure Temperature • These are blocks that contain a glimpse of weather information about a certain location at a specific time. • Includes • Temperature • Air Pressure • Cloud Coverage • Wind speed & Direction • Dew Point • Observed Weather 32 30.46 Observed Weather Cloud Coverage 15 Wind Speed Dew Point

  11. Station Models • There are a number of symbols to represent different information on a station model
