Question 7

Which weather conditions should be expected beneath a low-level temperature inversion layer when the relative humidity is high?

Smooth air, poor visibility, fog, haze, or low clouds.

A ground based inversion favors poor visibility by trapping fog, smoke, and other restrictions into low levels of the atmosphere. An inversion is a stable air mass and would have smooth air.
