Coastal Observatory

Forecast

In addition to observation, the forecast of meteorological, hydrodynamic and wave variables is a fundamental task both to know the future state of the sea and to make a diagnosis of the past behaviour of the sea

Operational Numerical Weather Prediction system

Currently a numerical forecast system that runs a series of models on a daily basis with the following characteristics is maintained:

Hydrodynamic models

  • 3D models ROMS for the Galician coast and MOHID for the estuaries.
  • Resolutions for 2 km regional and 300 m for Rías Baixas and the gulf of Ártabro.
  • Daily forecast of sea level, currents, salinity and temperature.

Atmospheric models

  • WRF model.
  • Resolution 4 km for Galicia and 1 km for Rías Baixas and the gulf of Ártabro.
  • Forecast of temperature, wind, pressure, precipitation, among other variables, twice a day.

Wave models

  • WWIII model for the open sea and SWAN for the coastal zone.
  • With resolution less than 50 m.
  • Forecast of significant height, period and wave direction.

These models are run with daily frequency or up to twice a day in the case of atmospheric models

All the above observations help to validate the models available to the Observatory and allow a highly accurate prediction of the ocean-meteorological conditions.

Numerical prediction on demand

Besides these daily models, the Observatory has the capability to run simulations on demand when necessary, either for a detailed study or for an emergency.

These on demand models can be:

  • High resolution hydrodynamic models: are models for current predictions in a restricted area with a resolution above 50 m.
  • Dispersion models of substances: they are pollutants, objects, faecal coliforms, hydrocarbons. They can be eulerian or lagrangian (particles) models.

In this regard, the Camgal Plan stands out, which has a rapid prediction system via the Aquasafe server.

Furthermore, a biogeochemical model, currently in the validation phase before being operationalized, will be incorporated in the near future.
