What type of air mass typically brings clear skies and high pressure?

• A. Cumulonimbus
• B. Continental Polar
• C. Tropical Maritime
• D. Maritime Polar

Answer: (B)

The option indicating "Continental Polar" air mass is indeed associated with clear skies and high pressure. Continental Polar air masses originate over cold land areas, leading to their characteristic cool and dry properties. As these air masses move into other regions, they often bring stable atmospheric conditions that result in fewer clouds and clear skies.

This stability is a result of the descending air associated with high pressure systems, which inhibits cloud formation. Consequently, areas affected by Continental Polar air typically experience calm weather, with high visibility and minimal precipitation. Such conditions are ideal for flying and are often associated with the onset of crisp, clear days, especially in the colder months.

In contrast, the other types of air masses mentioned do not generally bring the same conditions. Cumulonimbus refers to a type of cloud associated with thunderstorms and precipitation rather than clear skies. Tropical Maritime air masses are usually warmer and can bring humidity and clouds, while Maritime Polar air masses tend to bring cool and damp conditions, often resulting in overcast skies or precipitation.
