Weather Symbols and Station Models

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.

Fronts Four types  Warm  Cold  Occluded  Stationary Boundaries where air masses meet

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

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

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

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

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

Air Masses High Pressure Weather is usually sunny clear and dry

Station Models 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 Temperature Air Pressure Observed Weather Dew Point Cloud Coverage Wind Speed

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