6. The exchange of sensible and latent heat over the sea
Sammanfattning : Analysis of the neutral exchange coefficients for latent and sensible heat, CEN and CHN, based on measurements from the Östergarnsholms site in the Baltic Sea has been made. The data set used for the CHN study was based on the very accurate MIUU-instrument. LÄS MER
7. Peakflow response of stream networks : implications of physical descriptions of streams and temporal change
Sammanfattning : Through distributed stream network routing, it has quantitatively been shown that the relationship between flow travel time and discharge varies strongly nonlinearly with stream stage and with catchment-specific properties.Physically derived distributions of water travel times through a stream network were successfully used to parameterise the streamflow response function of a compartmental hydrological model.

8. Improved Cloud Parameterization in Global Climate Model : Aerosol effects and secondary ice production mechanisms
Sammanfattning : The response of clouds to the changes in climate is uncertain, and the representation of the cloud-climate feedback is a key challenge in the global circulation models (GCM) for future climate projections. Factors contributing to this uncertainty include processes that involve particles of various sizes and phases, as well as the interactions between these particles and the surrounding atmosphere.

9. Convection in large scale numerical models : parameterization and forecasts of precipitation probability
Sammanfattning : This thesis deals with the problem of including the effects of moist convection in the atmosphere in a large scale numerical forecast model and how to interpret and evaluate the predicted convective precipitation.Two methods for parameterizing convection in a large scale numerical forecast model are tested to find the most appropriate one for precipitation forecasts in the mid-latitudes.

10. Parameterization of state feedback gains for pole assignment
Sammanfattning : The pole assignment problem has been subject for research for a long time. For single-input single-output systems this problem is well understood but for multi-input multi-output systems the pole assignment problem is more complex. LÄS MER
