Airflow around a high-pressure system at the surface is characterized by surface divergence. In this context, high pressure systems are associated with descending air, which leads to an increase in surface pressure. As the air descends, it spreads outward from the center of the high-pressure area.

This outward movement of air results in surface divergence, where air flows away from the high pressure center. The divergence of air at the surface results in fair weather conditions, as descending air inhibits the development of clouds and precipitation. The cooling and stabilization of air also contribute to this phenomenon, leading to clearer skies.

The concept of surface convergence, upward airflow, or unpredictable air movement would not apply in this scenario, as they typically relate to low-pressure systems and turbulent conditions. Understanding this distinction clarifies why surface divergence is the correct description of airflow patterns around a high-pressure system.
