Presentation transcript:

* Weather maps are used to show current weather conditions in an effort to predict future weather conditions. * You need to know what each symbol means and how to interpret them to forecast the weather.

* Cold, dense air is moving toward warm, less dense air. * The warm air is pushed up to cool and form clouds as the cooler air replaces it. * The air on the front side of the boundary line is warmer than the air on the back side of the boundary line. * These fronts are usually fast moving and bring stormy weather and heavy precipitation followed by clearing skies and higher pressure.

* Warm air is moving toward cold air. * The warm, less dense air slides over the cold, more dense air. * The air on the front side of the boundary line is cooler than the air on the back side of the boundary line. * These fronts usually move slowly and bring steady rain or snow over many days.

* These fronts occur when neither the cool or warm air masses are strong enough to replace each other. * They tend to stay in an area for a long period of time, often bringing long periods of precipitation and clouds.

* Cooler, dense air close to the surface of the Earth. * Surrounded by winds flowing in a clockwise direction. * Usually brings dry conditions and fair skies.

* Warmer, less dense air above the Earth’s surface * Surrounded by winds moving in a counterclockwise direction. * Associated with the formation of storms.

Why does the Earth have weather? How do weather maps show how global patterns of atmospheric movement influence local weather?
