IPA: /bəˈrɒmətri/
KK: /bæˈrɑːmətri/
The method of measuring air pressure to help predict weather changes.
Meteorologists use barometry to forecast storms and changes in the weather.
Barometry → It is formed from "baro-" (from Greek "baros", meaning weight) and "-metry" (from Greek "metron", meaning measure). The word refers to the measurement of atmospheric pressure, which is related to weight.
Think of measuring 'weight' ('baro-') to understand how barometry relates to measuring atmospheric pressure.
