What is the standard lapse rate of temperature in the troposphere?

In the troposphere, the standard lapse rate of temperature is generally recognized as approximately 2°C for every 1,000 feet of altitude gain. This means that as an aircraft ascends, the temperature typically drops by this amount, reflecting the relationship between altitude and temperature in the lower layer of the atmosphere.

This standard lapse rate is used as a baseline for pilots and meteorologists to understand how temperature changes with altitude, which can impact aircraft performance and weather patterns. Deviations from this standard lapse rate can occur due to various atmospheric conditions, but the 2°C per 1,000 feet is an important benchmark in aviation and meteorological practices. Understanding this concept is crucial for pre-flight planning and assessing performance factors in flight operations.
