well at firs they used what is called a meltoregeon to build it and now they use
A reading of the air pressure. It's handy for rough weather predictions.
When air pressure increases, the aneroid barometer contracts, causing the needle to move clockwise or indicate a higher pressure reading. Conversely, when air pressure decreases, the aneroid barometer expands, causing the needle to move counterclockwise or indicate a lower pressure reading.
how do meteorologist use a barometer
It is called a barometer, first developed in the 1600's
I chipped the glass tabletop when I dropped the barometer.
no
no
meteorologists use barometers
i checked the barometer to see the air pressure
Since the barometer read that the air pressure was high, the boy brought an umbrella outside.
The device used to measure air pressure is called a barometer. It can be either an aneroid barometer or a mercury barometer, both of which are commonly used to measure atmospheric pressure.
