Model for Prediction Across Scales

This is a new way of thinking about weather modeling: Model for Prediction Across Scales. I'm pretty fascinated with how well this modeling method will work. The most interesting thing here is the change in grid convention. Notice the hexagonal shapes in the grid over the earth. The grid resolution is course for most of the globe, but is much higher over the United States. I'm currently playing with WRF models, but this model looks like something I'd like to look into. http://mpas-dev.github.io/
