Presentation transcript:

Fronts An area where air masses meet and do not mix Four Types Cold Warm Stationary Occluded

Cold Front Rapidly moving cold air running into slow moving warmer air Summer -Violent Thunderstorms Winter : Cold dry air

Warm Front Rapid moving warm air moving into slow moving cooler air Usually brings rainy weather

Stationary Front A warm air mass and a cold air mass meet and neither is moved

Occluded Front A warm air mass is caught between two cold air masses and forced up. Clouds form, may cause snow or rain.

Reading a weathermap

Meteorologist A scientist who studies the causes of weather and attempts to predict it.

Cyclone An area of low pressure Clouds/Rain Winds spin counterclockwise (N.H.)

Anticyclone An area of high pressure Dry/Clear weather Winds spin clockwise (N.H.)

News Weather Maps (cyclone) (anticyclone) Standard symbols include: Areas of high and low pressure (cyclone) (anticyclone)

Weather Maps Fronts Temperature Types of precipitation

Reading Weather Maps Isobars: lines that connect areas with equal pressure. Isotherms: lines that connect areas of equal temperature.

Weather Technology Weather Balloons: measure conditions in the atmosphere

Satellites: Provide Photos

3. Radar: track areas of rain and snow

4. Computers: make forecasts from collected data
