WebLapse rate is the rate of temperature decrease with height in the atmosphere. If we consider the hypothetical case of a bubble of air rising through a dry atmosphere with no mixing or heat exchange between the bubble and its environment, the bubble will expand and cool. The cooling is said to be at the dry adiabatic lapse rate (DALR). WebA decrease in temperature with height is called a lapse rate and while the temperature decreases with altitude, it is defined as positive because it is a lapse rate. Recall from …

This rate applies only if the air is not condensing. Dry does not mean that no water vapor is in the parcel, only that the parcel is not condensing. b) Wet adiabatic lapse rate (WALR) - 0.6° C for every 100 meters. This rate applies whenever condensation occurs within the parcel. improve my writing ai
