気圧
Meanings
1
atmospheric pressure; air pressure
General term for the pressure exerted by the atmosphere; used in weather reports, science, and everyday contexts.
The atmospheric pressure near the center of the typhoon is 950 hectopascals.
Changes in air pressure can sometimes cause headaches.
2
Technical unit of pressure used in physics and engineering; often abbreviated as atm.
One atmosphere is equivalent to about 1013 hectopascals.
Usage patterns
- 気圧が上がる／下がるatmospheric pressure rises/falls
Atmospheric pressure drops suddenly as a typhoon approaches.
- 〈数〉気圧X atmospheres (unit of pressure)
In the deep sea, water pressure can exceed 10 atmospheres.
- 気圧が低い／高いatmospheric pressure is low/high
In this area, the atmospheric pressure has been low for a while now.
- 気圧を測るto measure atmospheric pressure
You measure atmospheric pressure with a barometer.
Expressions
- 気圧の谷low pressure trough
