The lapse rate is the rate at which atmospheric temperature decreases with an increase in altitude. It is crucial in meteorology, as it influences weather patterns and cloud formation. The standard lapse rate is about 6.5°C per kilometer in the troposphere, but it can vary. If the air cools faster than this rate, it is considered "unstable," which can lead to rising air and potential storm development. Conversely, a slower cooling rate indicates "stable" air, which discourages vertical movement and generally results in calm weather conditions. Understanding the lapse rate is essential for predicting weather and understanding atmospheric processes.
