Nevertheless, weather predictions are imperfect and every forecast contains an element of uncertainty.
In that vein, meteorologists like to quote the 20th century statistician George Box: “All models are wrong but some are useful.”

Weather Maps in 3D Could Help Explain Extreme Climate Patterns
Graphics remain overwhelmingly two-dimensional, even though the atmosphere operates across three dimensions, and that presents limitations.
