Which weather outcome increases when polar air masses descend?

💡 Explanation

Increased descending polar air amplifies the temperature gradient, strengthening the Coriolis effect, therefore enhancing baroclinic instability and cyclone formation at mid-latitudes, rather than directly altering ozone depletion aloft because that is photochemical process.
