Which mechanism causes the formation of rainforests at latitudes near where Hadley cells converge?

💡 Explanation

When Hadley cells converge, warm, moist air rises undergoing adiabatic cooling because of decreasing pressure with altitude leading to condensation and rainfall. Therefore rainforests form, rather than upwelling which are driven by offshore winds or orographic lift which specifically requires mountains.
