Research for more accurate decisions and better information

Large areas of society are dependent on or influenced by the weather and water. Increased requirements with regard to the environment and a changed climate also provide new opportunities.

SMHI's research involves the development of tools and knowledge for many industries and areas of society. Mathematical calculation models are important tools which provide an integrated description of the processes on the ground, in the water and in the atmosphere.

An important aspect is also to develop methods to make better use of observations which form the basis of forecasting and developing scenarios and also to follow the development of the weather. Activities in the research department are based on extensive cooperation with other institutes and research establishments, both in Sweden and internationally.

How clouds influence our climate

A warmer climate could affect cloudiness on our planet. However, a change in cloudiness could in turn have repercussions on the climate. Research to better monitor clouds is now being intensified using satellites.

Satellites could provide answers

Vizualisation of future climate and consequences for cities

A new production with visualization technology presents future climate and consequences for cities. Presentations of Urban Water Vision was held in a Geodome at Stockholm Water Week.

Climate change a threat to sewage systems

Many cities could face problems with their sewage in the future. A research study for Stockholm shows that a change in precipitation, combined with a population increase, could bring disruptions as early as the middle of the century.

Phosphorus levels can increase significantly in connection with the spring flood. More measurements will improve knowledge. Spring flood increases phosphorus discharges

Air pollution in cities must decrease

It may be difficult to fully achieve clean air objectives also in the future. New results confirm that it is primarily local emissions caused by road traffic that need to be restricted. Air pollution in cities must decrease

The winds have not increased

It has not become windier in Sweden over the past hundred years. The wind climate is very varied, but a weak trend indicates that there is a decrease in the average wind speed and potential wind energy in the northern part of the country. Winds have not increased

Emissions reduction and adaptation necessary

Climate scenarios are important when trying to decide on emissions reductions but they are also important when adapting to changes. How to use climate scenarios was the theme for this year´s Rossby Centre Day at SMHI. Emissions reduction and adaptation necessary
