Weatherglass

A weatherglass is an instrument, specifically a barometer or sometimes a thermometer, used to forecast or observe changes in the weather. Historically, weatherglasses relied on the principle that changes in air pressure (measured by a barometer) or temperature (measured by a thermometer) often correlate with impending weather shifts. While the term can encompass both instruments, the barometer is most commonly associated with the term weatherglass. The readings are typically observed, recorded, and interpreted to predict future atmospheric conditions, such as rain, sunshine, or changes in wind. Though more sophisticated and precise meteorological tools exist today, the term retains a historical charm and is often used in antique or traditional contexts. The simple observation of changes in the weatherglass, as with a slow drop in atmospheric pressure indicating a storm on its way, can provide a good indicator of current and future conditions.

Weatherglass meaning with examples
