Around the clock, all days of the year, observations and measurements are collated at observation stations, both with balloon-borne instruments and from aircraft, ships and buoys. Satellites, weather radar and lightning sensors supply spatial information. Large quantities of collected data are structured, processed and analysed using very powerful computers. SMHI then makes forecasts, produces decision guidance for society and follows up climate and environmental development. Warnings in the event of extreme weather events are an important task.
SMHI delivers a wide range of forecasting and consulting services tailored to different user needs. In addition to industry-specific forecasting services, many assignments deal with climate and environmental issues relating to both air and water. Examples include tailormade climate analyses for urban planning, design calculations for wind power, and design flows and water levels for hydrological applications. Services are oriented to commercial, government and private users. Customers come from the construction, real estate, environment and energy sectors, among others.
SMHI conducts applied research in meteorology, hydrology, oceanography and climate. Researchers develop knowledge, models and tools that describe processes in the atmosphere, in the sea and on land. These are needed to improve SMHI projection models and decision guidance for practical public welfare. A great deal of the research conducted by SMHI is climate related.
