The temperature in the Earth's troposphere generally decreases as altitude increases. This phenomenon is known as the atmospheric lapse rate.
The standard rate of temperature decrease in the troposphere is approximately 6.5°C per 1000 meters of altitude gained. This value represents an average and can vary based on factors like latitude, season, and specific weather conditions.
Mathematically, this rate can be expressed as:
Rate = −6.5°C / 1000 m
The negative sign indicates a decrease in temperature with an increase in height.
