What is the characteristic of air movement in divergence?

The characteristic of air movement in divergence is that airflow spreads outwards from a region. Divergence occurs in the atmosphere when air flows away from a particular area, typically associated with sinking air and anticyclonic conditions. This outward movement can lead to a reduction in air pressure in the area, often resulting in clearer skies and stable weather.

Understanding divergence helps in recognizing patterns in weather systems and analyzing how air movement influences local climates. The other options describe different air movement behaviors: converging airflow focuses on air coming together, vertical movement relates to rising air which is linked to convection and instability, and stagnant airflow implies no significant movement or change. Therefore, the defining characteristic of divergence is clearly illustrated by its description of air spreading outward from a central point.
