barometric scale
1barometric scale — A scale on the dial of a sensitive altimeter. A pilot sets the barometric pressure level and uses it to measure the altitude shown on the altimeter. When existing pressure (QNH) is set, the altimeter reads the indicated altitude, and when the… …
2Barometric formula — The barometric formula, sometimes called the exponential atmosphere or isothermal atmosphere , is a formula used to model how the pressure (or density) of the air changes with altitude.Pressure equationsThere are two different equations for… …
3Saffir-Simpson Hurricane Scale — The Saffir Simpson Hurricane Scale is a classification used for most Western Hemisphere tropical cyclones that exceed the intensities of tropical depressions and tropical storms, and thereby become hurricanes. The scale divides hurricanes into… …
4International Temperature Scale of 1990 — The International Temperature Scale of 1990 (ITS 90) is an equipment calibration standard for making measurements on the Kelvin and Celsius temperature scales. ITS–90 is an approximation of the thermodynamic temperature scale that facilitates the …

6altimeter — /al tim i teuhr, al teuh mee teuhr/, n. 1. a sensitive aneroid barometer that is graduated and calibrated, used chiefly in aircraft for finding distance above sea level, terrain, or some other reference point by a comparison of air pressures. 2.… …
7sensitive altimeter — A form of pneumatic altimeter that is more accurate than a simple altimeter. It has an adjustable barometric scale by which the instrument can be adjusted to the existing barometric pressure. The altimeter pointer makes a complete revolution for… …
8Mittelgebirgslage — Höhenstufe steht für: die kartografische Höhenstufe, als vertikalen Abstand zwischen den Niveauflächen zweier Höhenlinien; siehe Äquidistanz (Kartografie) die barometrische Höhenstufe (engl. barometric scale factor) als vertikale Strecke, die… …
9pneumatic altimeter — An aneroid barometer whose dial is calibrated in feet or meters. It has a barometric scale that can be adjusted to any desired reference pressure. Its calibration is based on the specific lapse rate or the change in pressure with height …
10GEOGRAPHICAL SURVEY — Names The name Ereẓ Israel (the Land of Israel) designates the land which, according to the Bible was promised as an inheritance to the Israelite tribes. In the course of time it came to be regarded first by the Jews and then also by the… …
