← GeographyWhich outcome results when subtropical high-pressure belts weaken?
A)Increased ITCZ interannual position variability✓
B)Stratospheric ozone layer thickening occurs
C)Decreased sea surface temperature gradients
D)Strengthened thermohaline ocean circulation
💡 Explanation
Increased ITCZ position variability will transpire because the Hadley cell descent suppressing the ITCZ weakens, therefore the ITCZ meanders more irregularly into higher latitudes, rather than being confined by strong subtropical subsidence. The atmospheric pressure gradients change less.
