Which widespread effect occurs when prolonged high-pressure systems stagnate over continental areas during summer?

💡 Explanation

When high-pressure systems stagnate, subsidence intensifies because descending air warms adiabatically, suppressing vertical mixing and trapping pollutants, leading to temperature inversion. Therefore extensive thermal inversions form, rather than ozone increases, glacial cooling, or coastal changes which depend on different factors.
