Weather and Weather and ClimateClimate
Is there a Difference?
Weather• Weather is the condition of
the atmosphere at a particular time and place.
• Weather is affected by 4 atmospheric factors-
Heat Air Pressure Wind Moisture
Weather Info…..To forecast weather scientists must collect
data.Weather satellites orbit the planet and takes
pictures that are sent to radio and TV stations.
Radar sends out radio signals that are reflected from objects.
There are more than 400 weather stations across the US.
Weather maps and symbols tell us information about the weather we are having, and what kind of weather to expect.
Air Masses• Weather changes when a new air mass
moves over an area.• An air mass is a large body of air that has a
certain temperature and certain amt. of moisture.
• There are 4 kinds of air masses:
maritime tropical- warm, moist, ocean
maritime polar- cold, moist, ocean
continental tropical- hot, dry, land
continental polar- cold, dry, land
Weather Fronts• A front is the leading edge of an air
mass.• There are 4 types of fronts: Warm Front- rain and showers
followed by humid weather Cold Front- violent storms,
followed by fair cool weather
Wind• Wind is caused by a difference in
air pressure.• Wind is moving air (speed +
direction).• Air moves from an area of higher
pressure to and area of lower pressure.
Climate• Climate is the general
weather of an area over a long period of time.
• Climate is affected by Latitude, Elevation, Topography (shape of land), distance from water, global winds, and ocean currents.
