Ocean and Weather Forecasting systems use mathematical models in order to describe ocean and weather systems by using numerical methods.  Numerical methods are made by assimilating the dynamic, energy, physical processes of the ocean and the atmosphere. Assimilation models provide short term forecast for atmospheric, wave and hydrodynamic conditions of the marine environment. The institute of Oceanography, HCMR in provides an open access to the following forecasting systems: 

A) The POSEIDON weather forecasting system (Papadopoulos et al., 2008) with simulation period of 5 days.

B) The Mediterranean ocean circulation forecasting system (Korres et al., 2008) provides 5-days forecasts.

C) The Aegean Sea hydrodynamic model (Nittis et al., 2006; Korres et al., 2002) provides forecasts for 5 days ahead.

D) The WAM based wave forecasting system (under the supervision of Dr. Gerasimos Korres) provides wave forecasts for the next 5 days forced with hourly analysis and forecast winds produced by the POSEIDON weather prediction system.

E) The WAVEWATCH based wave forecasting system (under the supervision of Dr. Gerasimos Korres) provides wave forecasts for the next 5 days forced with hourly analysis and forecast winds produced by the POSEIDON weather prediction system.

F) The Oil spill fate and trajectory model (under the supervision of Leonidas Perivoliotis) is able to simulate not only the drift of the oil but also the chemical transformations under the specific environmental conditions. The oil slick is represented as “parcels” that have time dependent chemical and physical characteristics. The 3-D position of each parcel is calculated using advection and diffusion estimates while additional information such as wind and wave conditions and hydrological characteristics are requested for the simulation of the varying physicochemical properties.
