What is a temperature inversion?

• A. A drop in temperature with altitude
• B. When temperature increases with altitude
• C. A rise in temperature with daylight
• D. A decrease in temperature during nighttime

Answer: (B)

A temperature inversion occurs when the normal temperature gradient of the atmosphere is disturbed, resulting in a scenario where temperature increases with altitude instead of decreasing. Typically, in the troposphere, temperatures decrease with rising altitude due to the thinning of the atmosphere and loss of heat. However, during a temperature inversion, a layer of warm air traps cooler air below it. This phenomenon can lead to various weather conditions, including hazy skies and pollution accumulation near the surface. Understanding temperature inversions is crucial for dispatch operations, as they can affect aircraft performance and flight safety. For example, inversions can impact visibility and lead to turbulence. This fundamental knowledge is essential for making informed decisions regarding flight planning and operations.
