The HiresWindow is a community Weather Research and Forecasting (WRF) model based system integrated at ~4 - 5 km grid spacing and without utilizing parameterized convection. It has two component dynamical cores: the WRF-ARW developed and supported by NCAR/MMM, and the WRF-NMM developed by NCEP/EMC and supported by the Developmental Testbed Center (DTC) at NCAR. This model system runs over six different domains on the following schedule:

All runs are statically initialized by interpolation of NAM or GFS forecasts to generate the initial and lateral boundary conditions for the HiresWindow run, and are integrated to 48 h. Three or more hurricane runs during a given model cycle will preempt the larger HiresWindow domains from running.
