Root Breakdown
Root-derivedbaro- (weight, pressure, from Greek baros) + meter (measuring device) = a tool that measures the weight/pressure of the air. Because falling pressure signals storms, 'barometer' became a metaphor for any indicator of trends.

A barometer measures air pressure, and because pressure changes foretell the weather, the word leaped into metaphor: a 'barometer of public mood' is whatever reliably signals which way things are heading. The instrument that predicts storms became a word for anything that predicts change.
