it means it is going to rain
A barometer that uses mercury measures air pressure by monitoring the height of the mercury column in a tube. As air pressure changes, the mercury level rises or lowers in response. This instrument is called a mercury barometer.
When air pressure increases, the mercury in a barometer rises.
The reading on a barometer rises when the air pressure increases. This typically occurs when a high-pressure weather system moves into an area, leading to clearer skies and more stable weather conditions. Conversely, a falling barometer reading indicates decreasing air pressure, often associated with stormy or unsettled weather.
A mercury barometer is an instrument which can be used to forecast the weather. The fact that there is a barometer does not affect the weather. You need to see what the barometer shows and interpret it.

barometers with mercury measure air pressure. when the air pressure is high the mercury rises
The mercury rises. The lower atmospheric pressure allows the mercury to drop in level.
Do you mean the old barometer?

That is how you attach an arrow to the bow.
When air pressure goes up, the liquid in a mercury barometer goes down. This is because as air pressure increases, it pushes the mercury in the tube to rise, indicating higher pressure.
In case of an aneroid barometer with a spiral, there is an adjusting screw on the back. This screw can loosen or increase tension of the spiral.First you need to know the atmospheric pressure in your area, which can be found on meteorological sites. For example: 1005 mbar(hPa):change. This equals a rating of 753.8mm. There is an easy conversion method between the two, hPa/1.333= mm AND mm *1.333= hPa.(simplified but still very accurate)Thenjust adjust the screw to the right atmospheric pressure on the scale of the barometer, the arrow will be calibrated. (in fact you set the pressure of the vacuum inside the barometer.)Now every change in pressure will be pointed out by the arrow correctly.
