Question

Anticyclones generally bring clear skies and calm conditions because
a. a strong polar front keeps cold air well to the north.
b. adiabatic warming prevents condensation and latent heat release.
c. adiabatic cooling prevents condensation and latent heat release.
d. adiabatic warming promotes condensation and latent heat release.

Answer 1

Answer:

b. adiabatic warming prevents condensation and latent heat release.

Explanation:

"The subsiding air compresses as it descends, causing adiabatic warming. The eventually warmer and drier air suppresses cloud formation and thus anticyclones are usually associated with fine weather in the summer and dry, cold, and sometimes foggy weather in the winter. Calm settled weather is usually synonymous with anticyclones in temperate latitudes. Anticyclones are typically relatively slow moving features."
