what is a Barometer?
 |
| Water Barometer |
A
barometer is a scientific
instrument that is used to measure
air pressure in a certain
environment. Pressure tendency can forecast short term changes in the weather. Many
measurements of
air pressure are used within
surface weather analysis to help find surface
troughs, pressure systems, and frontal boundaries.

Barometers and
pressure altimeters are essentially the same
instrument but used for different purposes. An
altimeter is intended to be used at different levels matching the corresponding
atmospheric pressure to the
altitude, while a
barometer is kept at the same level and measures subtle
pressure changes caused by weather and elements of weather. The
average atmospheric pressure on the earth's surface varies between 940 and 1040 hPa (mbar). The
average atmospheric pressure at sea level is 1013 hPa (mbar).
