Weather Forecasting Technology
Weather balloon 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
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
Weather Forecasting
Anemometer An instrument used to measure wind speed
Faster the cups spin, the faster the wind is moving
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
Temperature
Isotherms Lines that connect areas of similar 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?
