    Weather Maps Weather Maps Presentation Transcript

    • Weather Maps Investigation 5-4
    • Weather Forecasting
      • How do we know what the weather is like today?
        • Weather is the condition of the atmosphere right now
      • What will the weather be tomorrow?
      • How can we get some idea of what will be going on with the atmosphere tomorrow?
      • Predicting weather is called forecasting .
      • Meteorologists study and measure weather data
      • Weather forecasting
        • How do you think meteorologists are able to forecast the weather?
    • Weather Maps
      • Tool used by forecasters
      • Information about weather variables
      • Meteorologists study variables and the patterns they make
      • Able to predict weather tomorrow
        • Based on today and yesterday
        • Look for patterns of change
    • 3-Day Weather Map Study
      • Look for information you recognize on the map
      • Look for changes from one day to the next
      • See if you can predict what the weather map for the next day might look like
    • Weather Maps
      • The end product of data gathering and organizing
      • Includes:
        • Weather variables - temperature, wind, pressure, moisture
        • Surface measurements
        • Atmospheric measurements with radiosondes
        • Satellite imagery
        • Structure of cold, warm, and stationary fronts
        • High- and low-pressure centers
        • General weather trends: major systems move west to east, air flows from high- to low-pressure, high-pressure centers are colder than low-pressure centers
    • Weather Maps Questions
      • What weather variables do meteorologists measure when preparing weather forecasts?
      • Describe three kinds of fronts and the weather they produce.
      • What causes wind?
      • Where do you think it is raining on the sample weather map? Where will it rain tomorrow?
      • Where do you think the wind is blowing on the sample weather map?
      • Where is it likely to be cold and dry?
    • Weather Prediction
      • Review your set of three weather maps.
      • Use the data and changes seen from day to day to forecast the weather for the next day again.
      • Where will the fronts be? Where will the wind and precipitation be?
      • Check your prediction against map 4.
      • What predictions were correct? What were you unable to anticipate?
    • Global Trends in Weather
      • Weather systems tend to move from west to east in North America
      • Wind tends to blow from areas of high pressure to areas of low pressure
      • Air tends to be cool and dry in high-pressure areas; warm and moist in low-pressure areas
    • Vocabulary
      • Surface measurements
        • weather data collected at Earth’s surface with weather instruments.
      • Atmospheric measurements
        • weather data collected in the atmosphere with radiosondes attached to balloons.
      • Weather map
        • a picture of weather data displayed on a map of part of Earth’s surface
    • Vocabulary
      • Cold front
        • occurs when a mass of cold air collides with a mass of warm air and pushes the warm air high into the upper atmosphere
      • Warm front
        • occurs when a mass of warm air collides with a mass of cold air and slides up over the cold air mass
    • Content
      • How are weather data obtained?
        • Weather instruments on the ground
        • Radiosondes on balloons
        • Satellite images
      • What kinds of data are displayed on weather maps?
        • Atmospheric pressure
        • Weather fronts
        • Precipitation
      • I-check 5 on Wednesday/Thursday (3/23-24)
      • Unit Test on Wednesday/Thursday (3/30-31)
