Summary:
This study investigated the diurnal cycle of precipitation in Sweden using hourly ground observations for 1996—2008. General characteristics of phase and amplitude for the diurnal cycle of precipitation, both in amount and frequency, were identified. The model fairly well captures the spatial pattern of the phase of the diurnal cycle. However, the warm season afternoon peak is simulated too early and too uniformly across the stations, associated with too frequent occurrences of convective rainfall events with relatively light intensity. These discrepancies point to the need to improve the convection parametrization and geographic representation of the model.

Mistra-SWECIA Science seminar: The effects of different energy sources and technological progress on climate change
Fossil energy and technological progress are two important factors that potentially influence climate change. Today, the main source of energy is fossil energy, and its use generates CO2-emissions with global warming as result. Technological progress can however improve the energy efficiency and potentially lead to the implementation of alternative clean energy sources that may partially or fully...
