What is the standard temperature lapse rate?

The standard temperature lapse rate is defined as the rate at which temperature decreases with an increase in altitude in the Earth's atmosphere. This rate is typically observed to be about 6.5°C for every 1,000 meters, which translates to approximately 2°C for every 1,000 feet. This relationship is significant for various fields, including aviation, meteorology, and environmental science, as it helps in predicting changes in weather patterns and understanding atmospheric behavior.

Recognizing the correct lapse rate is critical for pilots and meteorologists because it affects aircraft performance, flight planning, and weather forecasting. Understanding the lapse rate is also essential in explaining phenomena like thermal inversions and mountain wave conditions. The other temperature changes provided do not align with the established standard lapse rate, making them less relevant in this context.
