How is the ocean affected by climate change and what is the ocean’s role in the climate system? How is the Baltic Sea affected by a warmer climate and changes in the freshwater fluxes from land? These are the types of questions that SMHI’s research on ocean climate is trying to answer.

RCO (Rossby Centre Ocean model) is an oceanographic circulation model.This means the model calculates how the water flows and such thingswhich influences currents such as temperature, salinity and icecover. RCO is mostly used for the Baltic Sea and the Arctic Sea.

Numerical models are our main tools when doing oceanographic research. We develop and use a suite of sophisticated models describing the physical and biogeochemical processes in the sea. In some applications the models might be coupled together in a multi model system.

Extreme sea levels result in erosion and floods. SMHI is soon launching a new service for construction in areas close to the sea

Today's planning norms are based on historical information. However, the weather is likely to subject our buildings and factories to far tougher tests. Although there is great uncertainty surrounding the climate in the future, the risk assessments must be considerably sharpened up as we build for …

At sea, the shortest route isn't always the quickest. Waves, winds and currents are all significant factors when the skipper sets the course. SMHI is now working with one of the worlds largest service companies in shipping - GAC - to sell the Weather Routing service.

Raised sea levels of almost 1.5 metres in the Baltic could entail major problems for wastewater treatment. Plans are currently under development for a new treatment plant on the island of Gotland, which has to withstand the strains brought about by an altered climate.
