Presentation Transcript

  1. Influences on Weather

  2. EQ: What has an effect on the weather?

  3. Weather: The state of the atmosphere at a particular place and time. The amount of water in the air, the temperature of the air and the precipitation are all used to describe the atmosphere. Climate: The average weather conditions of a particular area.

  4. 5 Things that Influence Weather • Humidity • Temperature • Clouds • Air Pressure • Wind

  5. Water in the Air Humidity is the amount of water in the air. • Summer Days • Hygrometer So how does water in the air affect the weather? • Clouds • Precipitation

  6. Temperature Temperature is how hot or cold the air is. • Thermometer – measures temperature So how does temperature affect the weather? • Warmer air = more water vapor • Precipitation

  7. Clouds Cloud formation is affected by temperature and humidity. • Types • Weather predictors

  8. Air Pressure Air Pressure is the weight of the air. • The sun plays a role • Warmer, lighter, less dense air rises = lower air pressure • Barometer measure air pressure • Low pressure = warm temps, rain and storms • High pressure = cooler temps & clear skies

  9. Wind Windis the natural movement of air. • What causes it? • Air moves from high pressure to low pressure areas. • High pressure area close to a low pressure area = fast wind. • Big temp differences in the areas will make wind blow fast.

  10. Wind Continued • An anemometer measures wind speed. • A weather vane or wind vane tells the direction wind is blowing.

  11. Review Air Pressure, Moisture and Weather.asf

  12. Read About it • Read with a partner about the influences on weather on pages 97-99 in the EOG Science Book • On your own, answer questions 1-4 on pages 99-100.
