Barometer \Ba*rom"e*ter\, n. [Gr. ba`ros weight + -meter: cf. F. barom[`e]tre.] An instrument for determining the weight or pressure of the atmosphere, and hence for judging of the probable changes of weather, or for ascertaining the height of any ascent.
Note: The barometer was invented by Torricelli at Florence
about 1643. It is made in its simplest form by filling
a graduated glass tube about 34 inches long with
mercury and inverting it in a cup containing mercury.
The column of mercury in the tube descends until
balanced by the weight of the atmosphere, and its rise
or fall under varying conditions is a measure of the
change in the atmospheric pressure. At the sea level
its ordinary height is about 30 inches (760
millimeters). See Sympiesometer.

Aneroid barometer. See Aneroid barometer, under Aneroid.
Marine barometer, a barometer with tube contracted at bottom to prevent rapid oscillations of the mercury, and suspended in gimbals from an arm or support on shipboard.
Mountain barometer, a portable mercurial barometer with tripod support, and long scale, for measuring heights.
Siphon barometer, a barometer having a tube bent like a hook with the longer leg closed at the top. The height of the mercury in the longer leg shows the pressure of the atmosphere.
Wheel barometer, a barometer with recurved tube, and a float, from which a cord passes over a pulley and moves an index.
Douglas Harper's Etymology Dictionary
1660s, from Greek baros "weight" (see grave (adj.)) + -meter. Probably coined (and certainly popularized) by English scientist Robert Boyle (1627-1691).

Wikipedia
A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems and frontal boundaries.
Barometers and pressure altimeters (the most basic and common type of altimeter) are essentially the same instrument, but used for different purposes. An altimeter is intended to be transported from place to place matching the atmospheric pressure to the corresponding altitude, while a barometer is kept stationary and measures subtle pressure changes caused by weather. The main exception to this is ships at sea, which can use a barometer because their elevation does not change. Due to the presence of weather systems, aircraft altimeters may need to be adjusted as they fly between regions of varying normalized atmospheric pressure.
Barometer is a 2013 sculpture by Devin Laurence Field, to be installed at the newly constructed Hillsboro Ballpark in Oregon, United States. The stainless steel sculpture, commissioned by the City of Hillsboro, stands fifteen feet (4.6 meters) tall at the stadium's entry plaza. Installation of the work began on June 10, 2013.
Usage examples of "barometer".
According to the hypsometer and our aneroid barometer we were at a height of 11,075 feet -- this was in lat.
On the wall to my right were the instruments for measuring atmospheric pressure - a barograph and two mercury barometers.
It was a cold, grey day with low cloud, but the wind had veered and although he had seen neither barometer nor barograph he guessed the depression was passing north.
Overhead hung an ordinary tell-tale compass, and compactly placed on other parts of the wall were barometers, thermometers, barographs, and, in fact, practically every instrument that the most exacting of aeronauts or Space-explorers could have asked for.
When the barometer begins to fall, it is a sure warning of an approaching north-westerly wind, which is always accompanied by precipitation, and increases in force until the fall of the barometer ceases.
When this occurs, there follows either a short pause, or else the wind suddenly shifts to the south-west, and blows from that quarter with increasing violence, while the barometer rises rapidly.
The hypsometer and barometer, however, were not to be deceived, and both fell in precisely the same degree as they had risen before.
Outside the same state of things continues, and the barometer is going down.
Although I look at it at least every half-hour, the barometer will not go up.
A slight rise of both barometer and thermometer tells us that at last we are on the eve of the change we have been longing for.
This, together with the heavy swell and the pronounced fall of the barometer, showed that something might be expected.
The meteorological outfit on the Fram consisted of the following instruments and apparatus Three mercury barometers, namely: One normal barometer by Fuess, No.
The Adie standard barometer is so arranged that it is only necessary to read the summit of the mercury.
On the other hand, the normal barometer is not suited to daily observations, especially in the Polar regions, and the double reading entails greater liability of error.
That the Adie barometer is rather less sensitive than the other is of small importance, as the variations of atmospheric pressure at Framheim were not very great.
