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?
