Climate models divide Earth’s surface and atmosphere into grid boxes within which temperatures, winds, and ocean currents are computed. Like pixels in an image, the smaller these individual boxes, the clearer and more accurate the model they ultimately create. Clouds are too small to be resolvable in global models, but they can be resolved in high-resolution simulations in limited areas.
