What equipment do ecologists use?
Meterology is the study of what the weather is, will be, and the
causes of weather change.
Of primary interest to our bodies (and bodies of any animal or
plant) are temperature, humidity and wind speed. So a thermometer,
hygrometer and anemometer are good tools.
In predicting change, change of air pressure is of interest, so
a barometer is a good tool.
Also, a study of past weather is a good predictor of future
weather. Plus you can develop mathematical models combining all of
the above to predict weather. So a computer is a good tool for
modern meteorology.
