Dry Adiabatic Lapse Rate (DALR)
Dry Adiabatic Lapse Rate (DALR) : A meteorological term referring to the rate of decrease of temperature with height of a parcel of dry air ascending in the atmosphere without mixing or heat exchange. Numerically, the DALR is equal to about 1 degree Celsius per 100 metres (1 OC /100 m) or 3 degrees Celsius per 1000 feet (3 OC /1000 ft). Conversely, dry air descending in the atmosphere warms at the same rate. Note: Atmospheric Stability
