152:, or upper-level ridge or trough. Because ensemble forecasts naturally diverge as the days progress, the projected locations of meteorological features will spread further apart. A mean-spread diagram will take a mean of the calculated pressure from each spot on the map as calculated by each permutation in the ensemble, thus effectively smoothing out the projected low and making it appear broader in size but weaker in intensity than the ensemble's permutations had actually indicated. It can also depict two features instead of one if the ensemble clustering is around two different solutions.

Spaghetti diagrams were first used to track routing through a factory. Spaghetti plots are a simple tool to visualize movement and transportation. Analyzing flows through systems can determine where time and energy are wasted, and identify where streamlining would be beneficial. This is true not
