When looking at developing systems, one of the most important pieces of technology that we have are the spaghetti model plots. Aptly named for their unique pasta-like appearance, these charts depict many different outcomes or simulations for a given storm. Billions of computer calculations are run with different potential atmospheric conditions (i.e., temperature, cloud cover, winds, etc.). The result is shown to be the individual strand, often represented by separate colors. There are many potential outcomes, and no model is 100% accurate.
