← GeographyWhich outcome occurs when polar cell weakening increases mid-latitude storm frequency?
A)Polar jet stream meandering intensifies✓
B)Hadley cell expands towards poles
C)Oceanic salinity gradient strengthens sharply
D)Stratospheric ozone layer depletion accelerates
💡 Explanation
Increased polar cell weakening results in a weaker temperature gradient, so baroclinic instability increases, driving jet stream meandering because horizontal temperature differences sharpen. Therefore, storms increase rather than Hadley cell expansion involving different circulation patterns.
