Name one multimodal convergence zone and explain what it does.
a) Intertropical Convergence Zone, where trade winds converge, causing upward motion and heavy rainfall.
b) Arctic Convergence Zone, where Arctic air meets warmer air, creating stormy weather.
c) Polar Convergence Zone, where polar air masses collide, leading to freezing temperatures.
d) Subtropical Convergence Zone, where subtropical highs meet, resulting in stable atmospheric conditions.
