← GeographyWhich consequence results when descending air experiences rising pressure within subtropical gyre circulation?
A)Formation of arid desert regions✓
B)Intensification of coastal upwelling
C)Increased frequency tropical cyclone events
D)Strengthened polar front jet stream
💡 Explanation
Increased pressure in descending air leads to adiabatic warming; this suppresses cloud formation because of increased water capacity via subsidence inversion. Therefore arid conditions develop over areas like the Sahara. The other options reflect other causal scenarios, rather than warming dry air.
