While all clouds share the same basic composition, there's a wide variety of shapes and sizes. To understand these formations in greater detail we must first categorize their many variations.   NOVA video https://cdn.kastatic.org/googleusercontent/5-mPXhKOlJ96JjaCfkXzpBylSyJybfn-mqJHcGJ5QA8O4NP8VBLi044Lx3YclEOlx2UvHtDVr3JR3pwf_Iusv5xo Why so many cloud types?

Changes in weather are caused by air masses interacting to form weather fronts, such as cold or warm fronts. Because weather is so complex, weather predictions are only probabilities and not definite outcomes.
