Explanation:

When tropical rain forest climates are more dominated by the ITCZ than the trade winds (and with no or rare cyclones), so usually located near the equator, they are also called equatorial climates. Otherwise, when they are more dominated by the trade winds than the ITCZ, they are called tropical trade-wind climates.  The Intertropical Convergence Zone (ITCZ) is mainly responsible for such rain. The ITCZ forms because the sun shines directly on the equatorial region, the direct heat causes warm air to rise, which then cools and condenses then falls as rain.
