adiabatic lapse rate

См. также в других словарях:

  • adiabatic lapse rate — The rate at which the temperature changes as the air rises or falls without the heat being taken away from or given to the air mass. The standard adiabatic lapse rate is 3°C/1000 ft, 5.4°F/1000 ft, or 9.8°C/km when air is dry (dry adiabatic lapse …   Aviation dictionary

  • adiabatic lapse rate — noun The rate of decrease of temperature with height of a parcel of dry air lifted upward through the atmosphere with no addition or deletion of heat …   Wiktionary

  • adiabatic lapse rate — …   Useful english dictionary

  • dry adiabatic lapse rate — The rate of decrease of the temperature with the height of a parcel of dry air lifted adiabatically through the earth’s atmosphere in hydrostatic equilibrium. This lapse rate is g/cp, where g is the acceleration of gravity and cp is the specific… …   Aviation dictionary

  • saturated adiabatic lapse rate — The rate of cooling of ascending saturated air. It is approximately 1.5°C/1000 ft but may reduce to as little as 1°C/1000 ft in the warm saturated tropical regions. It also may exceed 2°C/1000 ft when the temperature of the air falls below the… …   Aviation dictionary

  • Lapse rate — The lapse rate is defined as the rate of decrease with height for an atmospheric variable. The variable involved is temperature unless specified otherwise.[1][2] The terminology arises from the word lapse in the sense of a decrease or decline;… …   Wikipedia

  • lapse rate — Meteorol. the rate of decrease of atmospheric temperature with increase of elevation vertically above a given location. [1915 20] * * * ▪ meteorology       rate of change in temperature observed while moving upward through the Earth s atmosphere …   Universalium

  • lapse rate — The rate of decrease of an atmospheric variable with height. However, the term normally refers to the fall of temperature with height. The three types of lapse rates referred to in meteorology are dry adiabatic lapse rate, saturated adiabatic… …   Aviation dictionary

  • dry adiabatic lapse rate — (DALR)   the rate of fall in air temperature by adiabatic change as unsaturated air gains altitude. Approximately 1蚓 per 100m …   Geography glossary

  • saturated adiabatic lapse rate —   the rate of fall in air temperature by adiabatic change as saturated air gains altitude. Varies between 4 and 9蚓 per 1000m. is slower than the DALR as latent heat is released during condensation …   Geography glossary

  • environmental lapse rate — The lapse rate in the surrounding air within which a volume of air is being lifted. The average rate is 2°C/1,000 ft. This should not be confused with dry adiabatic lapse rate (DALR) and saturated adiabatic lapse rate (SALR), in which the lapse… …   Aviation dictionary
