What is the standard temperature lapse rate in the troposphere?

The standard temperature lapse rate in the troposphere is defined as a decrease of approximately 2°C for every 1,000 feet of altitude gained. This rate is important for pilots and meteorologists because it helps predict changes in temperature with altitude, which can affect aircraft performance and weather phenomena.

In the troposphere, the temperature typically decreases as altitude increases, due to the decreasing pressure and density of the air. The lapse rate is crucial for understanding how atmospheric conditions will change during flight, particularly with respect to altitude, as well as for calculating aircraft performance metrics such as true airspeed and altitude corrections.

The values provided in the other options do not accurately reflect the standard lapse rate. While other lapse rates can occur due to specific atmospheric conditions, the established standard rate is most commonly accepted as 2°C per 1,000 feet in the troposphere.
