Autumn cooling in the Bay of Bothnia provides an opportunity for studying wind mixing, convection and restratification below the temperature for maximum density. Vertical temperature profiles for a 52 day period are analysed for the case of cooling of brackish sea water around the temperature of …

SMHI performed an oxygen survey within SLU-Aqua’s cruise; the International Bottom Trawl Survey, that covers the Skagerrak and the Kattegat. SMHI joined the cruise to perform CTD measurements in connection to each trawl and to take water samples for the annual oxygen survey. Samples for nutrients …

This report presents sea ice core measurements taken from the Bothnian Bay, March, 1984. The measurements were taken at different sites in the skerries and the basin area. The ice cores were analysed with respect to crystallographic structure using polarized light. Some ice cores were also used for …

A combination of a circulation anda diffusion model has been developed to be used for dispersion studies in the Baltic Sea. As the time scale of interest is from months up to several years a straightforward way to model the dispersion would require the circulation model to be run for a very long …

A two-dimensional circulation model (one vertical, one horizontal axis) was validated for a 3-week period, taking place in early fall 1977. For this time there exists independent measurement-based estirnates of the water turnover in Himmerfjärd estuary. Indata (forcing) of the model are: …

Satellite data (AVHRR) and in situ data of sea surface temperatures have been used to describe wind-induced upwelling along the Swedish coast of the Baltic.

The satellite data, transformed to isotherm charts  points out three sections of the coast where the upwelling is especially intense. …

A new forecasting model for water cooling in the Gulf of Bothnia and Lake Vänern is presented. The model elements consist of a transient Ekman model, where the turbulent exchange coefficients are calculated with a two-equation model of turbulence, a heat flux package for calculating the net heat …

The application of the HBV-6 conceptual runoff model to the Upper Narmada basin is surnmarized. The work includes an extensive investigation of the homogeneity of the precipitation stations anda discussion on the estimates of the potential evapotranspiration. A comparison between a lumped and a …

A model giving daily actual evapotranspiration values from synoptic data has been developed using results from the forest meteorological measuring site Velen in southern Sweden. The following submodels are included:

• Model for evaporation of rain water intercepted by the forest …

Syftet med föreliggande rapport är att sammanställa de mätningar som gjorts inom sedimenttransportnätets ram under åren 1967-79 samt att försöka generalisera resultaten till områden i Sverige där inga mätningar utförts.

Sedimenttransportnätet omfattar för närvarande ca 20 mätstationer i svenska …
