| aerostatics |
(used with a sing. verb) the branch of aeromechanics that deals with gases in equilibrium and with the equilibrium of airborne bodies or aircraft under changing atmospheric conditions. |
| ambient |
a type of instrumental music characterized by patterns of sound rather than melodic form or rhythmic structure, and which can be explicitly listened to or serve as background or atmospheric sound. [1/3 definitions] |
| aneroid barometer |
a barometer that uses a thin metal disk covering a partial vacuum, such that a change in atmospheric pressure results in a corresponding change in the shape of the disk and moves the indicator needle. |
| atmospherics |
(used with a sing. verb) static in radio reception caused by atmospheric electrical activity. [1/2 definitions] |
| barogram |
a visual record of atmospheric pressure over time, produced by a barograph. |
| barograph |
a barometer that automatically records the atmospheric pressure. |
| barometer |
a meteorological instrument that measures atmospheric pressure, esp. used to predict weather changes. [1/2 definitions] |
| barometric pressure |
the pressure of the earth's atmosphere, as measured by a barometer; atmospheric pressure. |
| baroscope |
an instrument that indicates changes in atmospheric pressure. |
| boiling point |
the temperature at which the vapor pressure of a liquid equals atmospheric pressure and the liquid boils. [1/2 definitions] |
| decompression sickness |
a painful and sometimes fatal condition caused by the formation of nitrogen bubbles in the blood, resulting from returning to atmospheric pressure too quickly from deep water or a compression chamber; aeroembolism; bends. |
| dehumidify |
to reduce the level of atmospheric moisture in. |
| depression |
a region with lower atmospheric pressure than nearby regions. [1/7 definitions] |
| element |
(pl.) the atmospheric conditions that constitute the weather. [1/6 definitions] |
| force of nature |
a hurricane, an earthquake, or other such powerful natural event, esp. one that is highly destructive, usu. generated by atmospheric or lithospheric conditions. [1/3 definitions] |
| greenhouse gas |
any atmospheric gas that absorbs and emits radiant energy and contributes to the greenhouse effect. |
| high |
an atmospheric condition of high pressure, often indicating fair weather. [1/14 definitions] |
| high-pressure |
of, concerning, or characterized by a pressure much higher than normal atmospheric pressure. [1/4 definitions] |
| hygroscopic |
attracting or easily absorbing atmospheric moisture. |
| low1 |
an atmospheric condition of low pressure, often indicating storms or violent weather patterns. [1/16 definitions] |
| meteorograph |
an instrument that measures and records several atmospheric or weather conditions at the same time. |
