2. Weather Forecasting

3. Weather Forecasting Weather balloon Weather Forecasting Technology
Carries electronic equipment into upper atmosphere
Wind sock or vane
Indicates wind directions
Doppler radar
Tracks precipitation
Weather satellites
Provides images/data of weather systems over large areas
Weather Forecasting Technology

4. Weather Forecasting Barometer
An instrument that measures atmospheric pressure
One end open so air pressure can move the mercury level within
The higher the air pressure, the better the weather

5. Weather Forecasting Anemometer
An instrument used to measure wind speed
Faster the cups spin, the faster the wind is moving

6. Weather Forecasting Thermometer How does temperature effect weather?
An instrument that measures and indicates temperature
Warm temperatures can bring humidity and rain
Cold temperatures can bring dry air and snow

7. Temperature
Isotherms
Lines that connect areas of similar temperature.

8. Temperature

10. Temperature Questions to Consider:
How do the isotherms help you to understand what weather is like in different parts of the country?
How might this be useful in forecasting the weather conditions in a particular area?
What patterns can you see in temperatures? Where is it typically warmer? Where are the temperatures typically cooler?
What reasons can you think of to explain the temperature patterns you notice?
