A temperature inversion would most likely result in which weather condition?
A
Clouds with extensive vertical development above an inversion aloft.
B
Good visibility in the lower levels of the atmosphere and poor visibility above an inversion aloft.
C
An increase in temperature as altitude is increased.✓ Correct Answer
Explanation
A temperature inversion is a layer in which temperature increases as altitude increases, the reverse of the normal lapse rate (PHAK Chapter 12). Because inversions are stable, they suppress vertical development and trap haze below them, so visibility is typically poor beneath the inversion and better above it, the opposite of the other option.
