Imagine air molecules flying around in a chamber. Cp expresses the specific heat content of a parcel of air at constant pressure. This region has few molecules of gases such as oxygen. For instance, the temperature falls from 15 degrees Celsius on the earth's surface to around -57 degrees Celsius in the tropopause. Stratos Jet Charters Is Not A Direct Or Indirect Air Carrier. A lapse rate is a rate of change of temperature with altitude. The Effects of Semi-Permanent Pressure Cells. The dry adiabatic lapse rate for the Earths atmosphere equals 9.8 C per kilometre (28.3 F per mile); thus, the temperature of an air parcel that ascends or descends 5 km (3 miles) would fall or rise 49 C (85 F), respectively. At 3,000 meters, the air reaches its dew point of 2 degrees Celsius. This is the rate at which the temperature changes with altitude. The rate at which the temperature of a rising air parcel changes without changing or losing heat to its surrounding is called the adiabatic lapse rate. As it rises farther, the air parcel continues to cool by expansion, but it cools at a slower or wet adiabatic rate. Beyond the lifting condensation level, air parcels cool at the moist adiabatic lapse rate. Find Out What Others Have Said About Stratos Jets. Lapse rates help determine atmospheric stability. You can use the print button to print out the tape. If an air parcel has a higher density than its surrounding air, it will sink towards the Earths surface.
