WebAs long as an air parcel is unsaturated (relative humidity < 100%), the rate at which its temperature will change will be constant. A 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. WebThe dynamic tropopause is based on potential vorticity (PV), rather than the WMO defined lapse rate definition that states (Lapse rate < 2K/km and does not exceed 2K/km for 2 …
