Understanding Weather and Climate: Key Differences and Influences
This presentation explores the differences between weather and climate, focusing on how different atmospheric factors influence them. Weather pertains to the state of the atmosphere at a given time and place, driven by heat, air pressure, wind, and moisture. It can change rapidly, especially with the movement of air masses and fronts. Climate, on the other hand, is the long-term pattern of weather in a region, shaped by elements such as latitude, elevation, and geographic features. Understanding these concepts is essential for interpreting forecasts and climate impacts.

Weather • Weather is the condition of theatmosphere 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 inair 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 fromwater, global winds, and ocean currents.
