Which weather outcome occurs when a high-pressure system intensifies?

💡 Explanation

Deserts migrate because intensified pressure increases the descending air enhancing the Hadley cell circulation. Air descends, warms, and dries, inhibiting precipitation; therefore, desert regions expand globally rather than coastal-upwelling, because that follows a different local circulation mechanism.
