environmental lapse rate: the rate of decrease of air temperature as altitude increases. Is compared to the dry adiabatic lapse rate or moist adiabatic lapse rate to determine vertical motions of an air parcel.
Environmental Lapse Rate
The rate of decrease of air temperature with height, usually measured with a radiosonde.
Environmental Temperature Sounding ...
Environmental Lapse Rate - The rate of temperature decrease with height in the troposphere.
Equatorial Low - A quasi-continuous belt of low pressure lying near the equator and between the subtropical highs.
Environmental lapse rate - the rate of temperature change actually measured in the atmosphere.
Advection - air and its properties, such as temperature, moving across something. Like a lake, or a map.
Environmental Lapse Rate
The actual change of temperature with height through the atmosphere.

If the environmental lapse rate is less than the moist adiabatic lapse rate, the air is absolutely stable -- rising air will cool faster than the surrounding air and lose buoyancy.
..
normal lapse rate is a global average rate of temperature reduction with elevation (6.4 °C/1000 m)
environmental lapse rate is the actual lapse rate on a given day at a specific location ...
Neutral StabilityAn atmospheric condition that exists in unsaturated air when the environmental lapse rate equals the dry adiabatic rate, or in saturated air when the environmental lapse rate equals the moist adiabatic rate.
absolutely stable airAn atmospheric condition that exists when the environmental lapse rate is less than the moist adiabatic lapse rate.
where V is the current speed, T the Kelvin temperature, g the acceleration of gravity, and γd and γ the dry-adiabatic and environmental lapse rates, respectively.
An atmospheric condition that exists when the environmental lapse rate is less than the moist adiabatic lapse rate.

tension of the water becomes negligible at wavelengths of greater than a few centimeters (see capillary wave). 2) Heterogeneous fluids, such as the atmosphere, have static stability arising from a stratification in which the environmental lapse rate ...
