Cloud Generation: Blocks and Biomes

Clouds should be made of blocks and come in many different shapes and sizes. They should have different formations and landscapes much like the land below, but based on actual cloud shapes irl. These would be cloud biomes, where you have clouds that are wide and short and clouds that are thin and tall. Weather would now be dependent on these formations. Rain would only fall under dark storm clouds, whether that be in a certain area or covering the entire sky. Which clouds generate may also be biome dependent. When in a desert, clouds will be less likely to generate, but in jungles, more so.
