Climate, Biomes and Spatial Patterns

Why are the world's great deserts near 30° and its rainforests near the equator? Learners build the three-cell model of global circulation, follow the seasonal migration of the ITCZ that drives monsoons, and trace ocean currents, upwelling and El Niño. They classify climates with Köppen codes from monthly data and explain the global pattern of biomes and their productivity, finishing with a transect across Africa.
