These are the regional and local domains used for the 3-day forecast system in the WRF operation. A total of 31 sigma-levels were specified for both regional and local domains and the thickness of each layer depends on the reference-state pressure, thiner in the surface boundary layer than in the upper atmosphere. The regional and local domains were run simultaneously through "two-way interaction." Two-way interaction is a nesting method in which the input from the coarse mesh is included via boundaries, and feedback to the coarse mesh covers the entire nested interior.

Red dots represent the locations of meteorological buoys in the computational domain. The number at each buoy is the name of that buoy. A total of 33 buoys are included in the data assimilation.
