What weather phenomenon commonly occurs directly beneath the ITCZ?

• A. Heat Waves
• B. Droughts
• C. Clear Skies
• D. Thunderstorms

Answer: (D)

The weather pattern in play is driven by convection from the ITCZ. This zone sits near the equator where the trade winds from the northern and southern hemispheres meet, causing warm, moist air to rise vigorously. As this air rises, it cools and condenses into thick clouds, producing frequent thunderstorms and heavy rainfall directly beneath the ITCZ.

Heat waves and droughts are linked to subsiding, dry air in other regions away from the ITCZ, not to the intense rising air here. Clear skies would be unusual in this belt because the constant deep convection keeps the sky cloudy. So the hallmark phenomenon under the ITCZ is daytime, vertical development of storms—thunderstorms.
