Barometer Meaning: Definition, Examples, and Translations
📉
barometer
[bəˈrɒmətər ]
Definition
weather measurement
A barometer is an instrument used to measure atmospheric pressure. It provides essential information for weather forecasting and helps meteorologists predict changes in weather conditions. By monitoring pressure changes, barometers can indicate approaching storms or fair weather. There are different types of barometers, including mercury and aneroid, each functioning on principles of pressure variation.
Synonyms
pressure gauge, weather gauge.
Examples of usage
- The barometer dropped significantly before the storm.
- He checked the barometer to see if the weather would change.
- The barometer in the cabin indicated clear skies.
- Using a barometer, she accurately predicted the rain.

Interesting Facts
Science
- Barometers can be used to predict short-term changes in weather, as air pressure is closely related to storm patterns.
- There are mainly two types: mercury barometers, which use liquid mercury, and aneroid barometers, which use metal chambers.
History
- The first practical barometer was invented by Evangelista Torricelli in 1643, providing a breakthrough in meteorology.
- During the 19th century, barometers became essential tools for sailors to predict weather changes at sea.
Pop Culture
- In literature, a barometer has been metaphorically used to gauge the mood or stability of a situation or environment.
- Songs often reference barometers as symbols of change, tying weather to emotional shifts.
Applications
- Painters and artists sometimes use barometric pressure to determine the best conditions for their work.
- Modern barometers are also found in smartphones and can be used for activities like hiking or planning outdoor events.
Origin of 'barometer'
Main points about word origin
- The word comes from the Greek words 'baros,' meaning weight, and 'metron,' meaning measure.
- It was in use since the early 17th century, reflecting advancements in scientific understanding of atmospheric pressure.
The word 'barometer' originates from the early 17th century, coming from the Greek roots 'baro-' meaning weight or pressure, and '-meter' meaning measure. The concept of measuring atmospheric pressure was critical for advancements in meteorology during the period. The first barometer was developed by Evangelista Torricelli in 1643, who used mercury to create a vacuum above mercury in a tube. This invention allowed for more scientific methods of observing weather patterns, leading to the early foundations of modern meteorology. Over time, different types of barometers evolved, allowing for increased portability and practicality in various fields, including meteorology, aviation, and even sailing.
