Aneroid barometer, a barometer the action of which depends on the varying pressure of the atmosphere upon the elastic top of a metallic box (shaped like a watch) from which the air has been exhausted. An index shows the variation of pressure.

A movement of the atmosphere opposite in character, as regards direction of the wind and distribution of barometric pressure, to that of a cyclone. -- An`ti*cy*clon"ic, a. -- An`ti*cy*clon"ic*al*ly, adv.

The upper, contrary-moving current of the atmosphere over a monsoon.

The revelation delivered to St. John, in the isle of Patmos, near the close of the first century, forming the last book of the New Testament.

Associated with them are certain painters of animals, as Troyon and Jaque, and of peasant life, as Millet and Jules Breton.…

Of or pertaining to weight, esp. to the weight or pressure of the atmosphere as measured by the barometer.

A tracing, usually made by the barograph, showing graphically the variations of atmospheric pressure for a given time.

An instrument for recording automatically the variations of atmospheric pressure.

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.

arometer so constructed as to inscribe of itself upon paper a record of the variations of atmospheric pressure.

Any instrument showing the changes in the weight of the atmosphere; also, less appropriately, any instrument that indicates - or foreshadows changes of the weather, as a deep vial of liquid holding in suspension some substance which rises and falls with atmospheric changes.

An instrument for recording both pressure and temperature, as of the atmosphere.

defense. Such a barricade as would greatly annoy, or absolutely stop, the currents of the atmosphere. Derham.
