Which phenomenon results when subtropical high-pressure cells intensify and expand poleward?

A)Increased desertification at mid-latitudes
B)Weakened jet stream due to reduced gradient
C)Elevated coastal fog formation in cold currents
D)Increased cyclonic activity near the equator

💡 Explanation

When subtropical high-pressure cells intensify and expand poleward, subsidence increases, leading to drier conditions because descending air warms and holds more moisture, inhibiting precipitation. Therefore, increased desertification occurs at mid-latitudes, rather than weakened jet streams, fog formation, or cyclonic activity which require different atmospheric conditions.
