NAM Hawaii is a high resolution nest, that runs within the larger NAM suite of models. NAM is a mesoscale model, which means that the numerical analysis is able to model land, and other features, at a higher resolution than in a global model, leading to improved forecast accuracy.

When looking at this model and comparing it to a global model such as GFS, you will notice that the NAM Alaska model accounts for the land features in the islands much better than the lower resolution models.
