Paper 1 · climatology
The Northeast and Southeast Trade wind air masses converge near the equator, producing rising, moist, unstable air, cumulonimbus development, and heavy convectional rainfall. What is this convergence zone called (give its full name or its common abbreviation)?
Model answer
Inter-Tropical Convergence Zone
Also accepted: ITCZ, Intertropical Convergence Zone
Explanation: This convergence of the Trade wind air masses near the equator is the Inter-Tropical Convergence Zone (ITCZ), where strong convectional uplift produces heavy rainfall; over Africa it migrates seasonally with the overhead sun.
