Meteorologists measure things like temperature, air pressure, wind and
humidity to make a good forecast. They must have good data….and they must
have a lot of it!

6. Tools used by meteorologists
A. Thermometer- measures temperature
B. Barometer- measures air pressure

6. Tools used by meteorologists
C. Anemometer- measures wind speed
Hygrometer- measures relative humidity
Ceilometer- measures cloud height

Radiosonde: sensors carried by a special balloon that gather weather data high up in the atmosphere and send it back by radio signal

Weather radar uses microwaves and a computer to show where rain occurs.
The Doppler Effect shows the change in wave frequency that occurs when light or sound moves toward or away from an
observer (like a siren).

7. Doppler RadarA. Doppler Radar plots how
quickly raindrops are moving towards/away from a radar station.
This helps to provide wind speeds.

Satellites- take pictures of cloud cover
Infrared satellites- special satellites that measure differences in temperature

8. Station model A. It is a record of weather data for
a particular site at a particular time.

8. Station model (Copy this picture and label)
B. Example Temperature
% of cloud cover
Wind Direction and speed

9. IsobarA. Lines that connect points of equal air
pressure. B. The closer the isobars, the higher the
wind!

Digital Forecast: a forecast using high-speed computers to calculate numerical data
Analog Forecast: comparing current events to past events to predict future conditions
** Most weather forecasts get less accurate over time, and are generally most accurate for 1-3 days.**
