The rate at which air temperature falls with increasing altitude.
‘A lapse rate is defined as the rate of change in temperature observed while moving upwards through the Earth's atmosphere.’
‘This lowering of temperature with altitude is called the ‘lapse rate’ and a standard lapse rate is about 3deg Fahrenheit per 1000 feet.’
‘Precise data on vertical rainfall distribution, temperature lapse rate, and the altitude of the temperature inversion on the windward slope exist for this oceanic wet tropical mountain.’
‘Even though the stratosphere has an opposite lapse rate to the troposphere because of the ozone absorption, the effect of increasing GHGs is the same, i.e. since it is above the effective radiating level, it will cool.’
‘Gale predicted and demonstrated a potential increase of transpiration with altitude when there is less than the average lapse rate of ambient temperature (about 0.6°C / 100 m at mid-latitudes).’
‘For this study a surface temperature of 0°C and a lapse rate of 6.4°C / km, the moist adiabatic, was assumed.’
‘My question is, how can the IGC compare GPS triangulation based on a Geodetic plane to an assumed lapse rate?’
‘Here, the environmental lapse rate, AB, increases with height, a condition known as a temperature inversion.’
‘No matter how favourable the weather may seem to be, stable lapse rates will ensure that no ‘weather’ is in the offing.’
‘Finally, the air-temperature field is reconstructed using elevations obtained from the DEM for each pixel and the specified lapse rate.’
‘The instrument problems uncovered by these papers indicate that there is no longer any compelling reason to conclude that anything strange has happened to lapse rates.’
‘Differences in high-elevation transpiration rates between equatorial and middle-latitude mountains are greater at low lapse rates than at high ones.’
‘I think your readers might be interested in the lapse rate on Mars.’
‘They just don't seem to understand that you cannot compare GPS altitude, which measures by triangulation to a geodetic plane, to a baro-altimeter that measures based on an assumed lapse rate.’
