Which climate outcome results at the polar high?

💡 Explanation

Air aloft cools and descends at the polar high because radiative cooling at the poles drives atmospheric subsidence, contributing to stable, descending air and low precipitation due to adiabatic compression; therefore descending air creates desert conditions, rather than unstable, rising air for storms or enhanced rainfall areas.
