A temperature inversion is a weather phenomenon where a layer of warm air traps cooler air near the ground. In this scenario, the temperature actually increases with altitude, which is contrary to the normal atmospheric conditions where temperature typically decreases with height. This creates a stable atmosphere where the cooler air below is prevented from rising, leading to a variety of potential weather effects.

Inversions can also lead to the formation of fog or low clouds, as the cool air can reach its dew point, forming moisture in the vicinity. While this phenomenon doesn't directly produce thunderstorms and heavy rain, the trapped cooler air can result in stagnant air conditions and may contribute to pollution buildup or haze.

Therefore, recognizing that in a temperature inversion, the temperature increases with altitude is crucial for understanding the implications it has on weather and flight conditions.
