What effect does high relative humidity have under a low-level temperature inversion?

High relative humidity under a low-level temperature inversion typically leads to the formation of fog and low stratus clouds. A temperature inversion occurs when a layer of warm air traps cooler air at lower altitudes, which can create stable atmospheric conditions. In this scenario, as the relative humidity rises, the air becomes saturated, allowing condensation to occur. This process can result in the creation of fog, which forms when the moisture in the air condenses into tiny water droplets close to the ground, limiting visibility. Additionally, low stratus clouds may form as moisture accumulates in the cooler, stable air beneath the inversion layer. This relationship between high humidity and the presence of an inversion is significant in aviation, as it directly impacts visibility conditions and flight safety.
