The early warning and marine forecast system is based on the below described numerical models.
The Global Forecast System (GFS) produced by the National Center for Environmental Prediction (NCEP-NOAA) is used as a weather forecast model. The atmospheric conditions from the GFS are downscaled for the Arabian Gulf and Dubai coast domains. The main predictive data are air pressure, temperature, specific humidity, precipitation, total cloud, water condensate, turbulent kinetic energy and wind components
The Regional Ocean Model System (ROMS) is used to setup the hydrodynamic domains of both the Arabian Gulf with coarse resolution and Dubai coastal zone with fine resolution. The main model outputs are the water levels and currents.
A regional wave model was developed using (SWAN) to simulate spatially-varying wave conditions in the Arabian Gulf and Dubai regions. The key model outputs are the significant wave height, peak wave period and mean wave period and peak wave direction.
Oil Spill Model
A web based oil spill tool, OILMAP, is integrated with Dubai forecast system. This tool is capable of assessing the fate of oil spills released in the sea. It can be operated by a user at DM to predict the oil spill weathering and trajectory.
The Inundation tool is available to predict inundation of land adjacent to the coast and to Dubai creek due to the occurrence of abnormally high water levels depending on the predicted seawater elevation.
