Which mechanism establishes desert biomes due to atmospheric cells?

A)Hadley cell descent and adiabatic compression
B)Polar cell ascent and precipitation maxima
C)Ferrel cell instability and cyclogenesis
D)Jet stream blocking and persistent anticyclones

💡 Explanation

Hadley cell descent causes dry conditions because as air descends, adiabatic compression warms it, lowering relative humidity and inhibiting precipitation to produce deserts; therefore, descent zones drive desert formation, rather than ascent which causes rainfall.
