Research is mainly conducted on short-term forecasts and impacts of climate change on the sea and the marine ecosystem. The unit thrives to develop state-of-the-art operational ocean and climate models to provide support to climate services and decision makers for ocean management and protection.

Wind, waves and currents are crucial factors in choosing a route at sea. SMHI's services for shipping have the potential to reduce fuel consumption and thereby emissions by just over 430,000 tonnes of carbon dioxide a year - which equates to the annual emissions from more than 170,000 cars.

In autumn year 2000 and winter-spring 2001 the precipitation in the catchment area of Lake Vänern was higher than normal. During spring 2001, the flow in river Göta älv was around 1200 m3/s, nearly three times higher than the average indicating extreme conditions. The flow in the smaller rivers Last updated: Apr 23, 2014

collaborated in a series of projects focused on hydrological modelling, climate change impacts on hydrological dynamics, analyses of extremes for infrastructure dimensioning, seasonal forecasts for food security, operational flood forecasting and using them to alert society and reduce the impacts of floods Last updated: Dec 11, 2024

Forecasts from SMHI are an important piece of the puzzle for safer and more efficient shipping, which is the aim of the EU’s Sea Traffic Management (STM) project. Today, international shipping is relatively unregulated when compared to aviation. The route a particular ship is planning to take is Last updated: Mar 20, 2017

between two consecutive wave crests. The wave period is the time interval between two consecutive wave crests. The wave velocity (celerity) equals the wave length divided by the wave period. Sea reports give the significant wave height. This is calculated from the height of all the waves during a 20 Last updated: Apr 23, 2014

strong enough and blows for long enough, the whole entire volume of the warmer surface water is blown out to sea, and the colder layer of water underneath (30 m) is brought to the surface. The deeper water often has a temperature of 5-10 degrees and the water out at sea is warmer than at the coast Last updated: Apr 23, 2014

Furthermore, the ice cover in the Baltic Sea during the latest ice season measured the smallest surface area since 1720.   Last updated: Apr 23, 2014

Risks for flooding SMHI also compiles current knowledge for other areas such as flooding risks around Lake Vänern and Lake Mälaren. - Broadly speaking, all public sectors are affected by the changing climate. The report provides us with the necessary knowledge base relating to climatic change in Last updated: Apr 23, 2014
