Rogers said it's best to look to the global models first for agreement, and then to the localized models for greater detail. “The problem is people will latch on to an exact deterministic model whether it’s good or bad for them … but the main thing to pull away from spaghetti models is how much agreement the models show.” “We certainly have lots of people in the weather community that see, ‘This model is coming to my house so that’s the one that’s going to happen,' ” said Rogers. The European Center for Medium-Range Weather Forecasting Model (ECMWF) is widely considered the best for predicting global weather patterns and has been beating the other models in terms of accuracy, but looking to rely on one model over another isn’t the correct approach, said National Weather Service Meteorologist Ryan Rogers. There are also models - called consensus models - that use various combinations of the other models to generate an all-together new model. There are six global forecasting models that are used all over the world to predict daily weather, and any number of smaller, regional models that use the global models as a starting point to make more localized predictions. If each line in a spaghetti model represents the predictions of a different forecast, the natural question is which model is best.

The National Hurricane Center in Miami relies on a blend of six models to predict a storm’s path, each the result of a series of baffling computations done by supercomputers all using different equations and starting conditions.Īs a result, different models make different predictions about a storm’s path, resulting in the splayed-out plot of lines the storm-watching public has come to know as “spaghetti models.” When it comes to tracking hurricanes, however, not all forecasting models are created equal. The data is updated every month.As yet another hurricane prepares to batter Florida’s Gulf Coast, all eyes are on the forecasting models that aim to track the exact path and intensity of the potential devastation.
