JMA Non-Hydrostatic Model (NHM): Puerto Rico and US Virgin Islands Dynamical Downscaled Climate Change Projections

The Japanese Meteorological Agency Non-Hydrostatic Model (NHM) is nested inside the Regional Spectral Model (RSM) at 10 km grid resolution which in turn is forced at the lateral boundaries to dynamically downscale two general circulation models (GCMs) that participated in the Coupled Model Intercomparison Project (CMIP5). The downscaled regional climate change projections were developed for two twenty-year timeslices for the high Greenhouse Gas Emission Scenario, RCP8.5. These climate change projections were developed to provide information about climate change for various climate change applications within Puerto Rico and the US Virgin Islands. In particular, the model output parameters were saved in response to the needs of physical scientists and other stakeholders within the islands, including ecologists, biologists, and hydrologists. The simulations are nested one-way from the GCMs with a 138.75-10-2km nest.
