What is the standard temperature lapse rate in the troposphere?

The standard temperature lapse rate in the troposphere is approximately 6.5 degrees Celsius per 1,000 meters of altitude, which is roughly equivalent to about 2 degrees Celsius per 1,000 feet. This average lapse rate is crucial for understanding how temperature decreases with altitude, influencing weather patterns, aircraft performance, and atmospheric stability.

The lapse rate reflects the cooling of the air as altitude increases due to the decreasing atmospheric pressure and density, leading to a reduction in the air's capacity to hold heat. This characteristic of the troposphere is essential for pilots and meteorologists as it impacts flight operations and weather predictions. It's important to remember that while the lapse rate varies under different atmospheric conditions, the standard rate provides a reliable baseline for a variety of applications in aviation and meteorology.
