The ECMWF OCEAN5 system is a new global eddy-permitting ocean-sea ice ensemble reanalysis analysis system. This Technical Memorandum gives a full description of the OCEAN5 system, with the focus on its Behind-Real-Time (BRT) component, the reanalysis product ORAS5. The OCEAN5 Real-Time (RT) component includes all upgrades developed for ORAS5 and runs daily using the latest observations and forcing fields from the operational Numerical Weather Prediction (NWP).

Specific humidity gives an indication of the amount of moisture within a sample of air (in g of water vapour within a kg of air, g kg⁻¹). The chart shows the specific humidity at 1000 hPa and 925 hPa levels and...
