Which outcome results when the Ferrel cell weakens?

💡 Explanation

If the Ferrel cell weakens, the Hadley cell dominates a wider area leading to poleward expansion of the subtropical high-pressure zone because of subsidence inhibiting precipitation; therefore the deserts shift poleward with little precipitation, rather than compressed temperate zones.

• Which process explains magma composition variation causing island arcs?
• Which geographic feature limits orographic precipitation on the leeward side of the Andes mountains during strong prevailing winds?
• Which feedback occurs when coastal upwelling of nutrient-rich water causes a phytoplankton bloom that decreases surface albedo?
