Radiation fog can only form as long as no temperature inversions exist in the lower troposphere.

Question

Quizplus · Accepted Answer

Radiation fog forms when the ground cools rapidly, causing the air to cool and reach its dew point, creating fog. Temperature inversions can actually enhance the formation and persistence of radiation fog by trapping the cool, dense air close to the surface. Therefore, radiation fog can form even when temperature inversions exist in the lower troposphere.
