Denna rapport är resultatet av ett uppdrag från Naturvårdsverket till SMHI (NV dnr 235-5045-04H k), som genomförts under hösten 2004. Syftet är att få en överblick över vilka aktörer som för närvarande är aktiva med att analysera eventuella effekter på samhället och att kartlägga anpassningsbehov. …

This report presents the latest version of the Rossby Centre regional atmospheric model, RCA3, with focus on model improvements since the earlier version, RCA2. The main changes in RCA3 relate to the treatment of land surface processes. Apart from the changes in land surface parameterizations …

A regional climate model (RCM) and oceanographic, hydrological and digital elevation models were applied to study the impact of climate change on surface wind, sea level, river discharge, and flood prone areas in the Baltic Sea region. The RCM was driven by two global models and two emission …

The impact of a CO2 stabilisation on the Swedish climate is investigated with the regional climate model RCA3 driven by boundary conditions obtained from a global coupled climate system model (CCSM3). The global model has been forced with observed greenhouse gas concentrations from pre-industrial …

The demand is growing for practical information on climate projections and the impacts expected in different geographical regions and different sectors. It is a challenge to transform the vast amount of data produced in climate models into relevant information for climate change impact studies. …

Närsalthalterna uppvisade, i stort, normala värden i alla områden, med undantag för silikat, som var kraftigt förhöjd i Arkona- och Bornholmsbassängerna och i Öresund där även fosfathalten var hög. Syrehalten vid botten i västra Arkonabassängen var under den normala. 2,2 ml/l. I övriga Östersjön …

The need for long time series of gridded meteorological data with a fine spatial and temporal resolution has increased in recent years. The requirements for this type of gridded meteorological data fields arise from many different areas of the society, in connection to atmospheric environment …

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 …

Närsalthalterna uppvisade, i stort, normala värden i de flesta områdena, med undantag för fosfat och silikatkoncentrationerna, som var förhöjda i södra Östersjön och i Öresund. I centrala Skagerrak hade samtliga närsalter högre koncentrationer än normalt. De högsta värdena vid fluorescensmätningar …

The main goal of this report is to compile and present available data on algal toxins in blue mussels from the west coast of Sweden. The hazards associated with the consumption of mussels are mostly dependent on the occurrence and composition of toxic algae in the areas where shellfish are grown. …
