What does high pressure generally mean for weather conditions?

High pressure systems are generally associated with sinking air, which suppresses cloud formation and leads to stable weather conditions. As air descends, it warms and dries, often resulting in clear skies. This stability typically inhibits precipitation, making high pressure regions favorable for sunny weather and calm conditions. The absence of moisture, combined with the upward movement of air being restricted, leads to the prevalence of nice weather. Thus, the correct choice recognizes that high pressure usually corresponds with clear skies and stable weather, contrasting with the precipitation and instability that often accompany low pressure systems.
