The lapse rate is the rate at which an atmospheric variable, normally temperature in Earth's atmosphere, falls with altitude. Lapse rate arises from the word lapse, in the sense of a gradual fall. In dry air, the adiabatic lapse rate is 9.8 °C/km (5.4 °F per 1,000 ft). At Saturated Air Lapse Rate (SALR), where value is 1.1 … See more A formal definition from the Glossary of Meteorology is: The decrease of an atmospheric variable with height, the variable being temperature unless otherwise specified. Typically, the lapse … See more The temperature profile of the atmosphere is a result of an interaction between thermal conduction, thermal radiation, and natural convection. … See more The environmental lapse rate (ELR), is the rate of decrease of temperature with altitude in the stationary atmosphere at a given time and location. As an average, the See more • Adiabatic process • Atmospheric thermodynamics • Fluid dynamics • Foehn wind • Lapse rate climate feedback See more These calculations use a very simple model of an atmosphere, either dry or moist, within a still vertical column at equilibrium.

WebMay 8, 2024 · environmental lapse rate (ELR) The rate at which the air temperature changes with height in the atmosphere surrounding a cloud or a rising parcel of air.The overall average rate is a decrease of about 6.5°C/km, but the rate varies greatly in different regions of the world, in different airstreams, and at different seasons of the year. WebThe discrimination is due to the problematic assumptions (assuming a standard lapse rate) associated with reduction of sea level from high elevations. The Dead Sea, the lowest place on Earth at 430 metres (1,410 ft) below sea level, has a correspondingly high typical atmospheric pressure of 1065 hPa.
