← GeographyWhich phenomenon arises when the ITCZ migrates across the equator, disrupting normal Hadley cell circulation?
A)Upwelling along continental coastlines
B)Reversal of seasonal monsoon patterns✓
C)Intensification of polar jet stream
D)Formation of stratospheric ozone holes
💡 Explanation
When the ITCZ crosses the equator, Hadley cell circulation shifts due to changes in solar insolation leading to a reversal of wind direction required to maintain convergence. Therefore, reversed monsoon patterns result, rather than upwelling, intensified jet stream, or ozone holes that depend on different processes.
