← GeographyWhich convection pattern maintains Earth's tropical rainfall because high insolation near the equator creates convergence?
A)Hadley cell circulation✓
B)El Niño oscillation
C)Rossby wave formation
D)Geostrophic balance breakdown
💡 Explanation
Hadley cell circulation transports heat from the equator, which causes air to rise (convergence and rainfall) and then sink at 30° latitude. Therefore, it sustains tropical precipitation belt rather than oscillations, Rossby waves, or imbalances, because those affect mid-latitudes.
