In a new bilateral project between Sweden and Brazil, researchers and experts will share knowledge about heat in cities. Contact has been made with the Brazilian city of Fortaleza, where they will map the urban climate in order to see how heat is distributed in the city and find the city’s cool …

How unusual is it that the May weather is as hot as it was this year in Sweden? Will this become commonplace in a changed climate? At SMHI, researchers and climatologists have analysed weather statistics and concluded that it was uncommonly warm and that it represented a record high which could …

Regional climate modelling is a key element in laying the groundwork for decisions on matters where climate change affects society. To expand local knowledge of regional climate modelling, the CORDEX network is currently arranging workshops for regional climate modelling with the aim of increasing …

The warm and sunny weather in May, in combination with calm winds, had warmed the surface water, and the surface water temperature was above normal at all visited stations. High phytoplankton activity was found mainly at the stations in the Baltic Proper, indicating ongoing spring bloom. Large …

On the following pages, you can read about SMHI's personal data management, what personal data is, how and when we process your personal information, what rights you have and what the legislation stipulates.

The integrated (0-10 m and 0-20 m) chlorophyll a concentrations were low but within normal for this month at all stations in the Kattegat and Skagerrak areas, except for Å15 where chlorophyll concentrations were higher than normal. The chlorophyll fluorescence maxima in these areas were caused by …

Data assimilation creates the starting values ​​(weather situation) for a numerical prediction model. It is one of the most important components of a forecast system.

In the beginning of June, twenty-two decision-makers from Eastern Africa conclude the Sweden segment of their participation in the “Climate Change – Mitigation and Adaptation” educational program at SMHI in Norrköping. In total, approximately 330 individuals from nine countries across three …

The spring bloom was ongoing in almost the whole area and large peaks in fluorescence was measured with the CTD.

The deep water in large parts of the Baltic Proper has oxygen concentrations near zero. Completely oxygen free areas, when toxic hydrogen sulphide is formed, were measured in the …

This report presents the main results of the Swedish national marine monitoring programme of the pelagic during 2017. The monitoring data of hydrography, nutrients and phytoplankton are analysed for the seas surrounding Sweden: Skagerrak, Kattegat, The Sound, Baltic Proper, Bothnian Sea and …
