Question

which feature characterizes a high - pressure system? counterclockwise air flow unstable weather conditions frequent precipitation clockwise and outward air flow

Explanation:

In a high - pressure system in the Northern Hemisphere, air flows clockwise and outward due to the Coriolis effect. Counterclockwise air flow is characteristic of low - pressure systems in the Northern Hemisphere. High - pressure systems are associated with stable weather and generally little precipitation.

Answer:

D. Clockwise and outward air flow
