atmospheric pressure
81pressure altimeter — Meteorol. an aneroid barometer adapted for measuring altitude by converting the indicated atmospheric pressure to altitude according to a standard relationship. Cf. standard atmosphere. * * * …
82pressure cooker — noun A sealed cooking vessel that allows cooking in greater than atmospheric pressure and at a temperature above the boiling point of water …
83pressure cabin — compartment in the craft of a vessel whose atmospheric pressure can be regulated …
84pressure suit — specially sealed garment that protects a pilot s body in situations of low atmospheric pressure …
85Atmospheric reentry — refers to the movement of human made or natural objects as they enter the atmosphere of a planet from outer space, in the case of Earth from an altitude above the edge of space. This article primarily addresses the process of controlled reentry… …
86Atmospheric physics — is the application of physics to the study of the atmosphere. Atmospheric physicists attempt to model Earth s atmosphere and the atmospheres of the other planets using fluid flow equations, chemical models, radiation balancing, and energy… …
87Atmospheric circulation — is the large scale movement of air, and the means (together with the smaller ocean circulation) by which heat is distributed on the surface of the Earth. The large scale structure of the atmospheric circulation varies from year to year, but the… …
88Atmospheric refraction — is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of altitude. Atmospheric refraction near the ground produces mirages and can make… …
89Atmospheric tide — Atmospheric tides are global scale periodic oscillations of the atmosphere. In many ways they are analogous to ocean tides. Atmospheric tides can be excited by:*The regular day/night cycle in the insolation of the atmosphere *The gravitational… …
90Atmospheric instability — is a condition where the atmosphere is generally considered to be unstable and as a result the weather is subject to a high degree of variability through distance and time [ [http://www.ace.mmu.ac.uk/eae/Weather/Older/Stability of Air.html… …
