aneroid barometer
Học thuậtThân thiện
The weather station uses an aneroid barometer to monitor atmospheric pressure.
Definition
Noun: - A barometer that measures atmospheric pressure without using liquids: An aneroid barometer is a scientific instrument for measuring air pressure. Its key characteristic is that it operates mechanically using a small, flexible metal box called an aneroid cell, rather than relying on a column of liquid like mercury or water.
Usage
- This term is used specifically to describe a type of barometer. It is a technical term common in meteorology, aviation, and scientific contexts.
- It is typically used as a countable noun (e.g., , ).
Examples
- Noun:
- The ship's captain checked the aneroid barometer for signs of an approaching storm.
- Modern aneroid barometers are more portable than traditional mercury barometers.
- A sudden drop in the reading of the aneroid barometer often indicates low pressure and bad weather.
Advanced Usage
- "Aneroid" as a descriptive adjective: The word "aneroid" itself means "operating without liquid" and can modify other nouns, though this is less common.
- The device uses an aneroid mechanism to sense pressure changes.
Variants and Related Words
- Barometer (n): The general term for any instrument that measures atmospheric pressure.
- Aneroid (adj): Describing something that operates without fluid, particularly in the context of pressure measurement.
- Barograph (n): A recording aneroid barometer that produces a continuous chart of pressure changes over time.
Synonyms
- Dry barometer: A less common synonym emphasizing the lack of liquid.
- Mechanical barometer: A descriptive synonym highlighting its operational mechanism.
Antonyms
- Mercury barometer: A barometer that uses a column of mercury to measure pressure.
- Water barometer: A barometer that uses a column of water.
