The debate on the 'science of climate change' focuses mainly on 1) whether the climate is changing and 2) if mankind's activities play a role in climate change. This report was written after the symposium on "Man-made versus natural climate change; Changes in climate during the past 100 years from Last updated: Apr 06, 2020

, and in bordering upstream areas. The model encompasses also the influence of lakes and dams on the flow dynamics. Further, the model describes river regulations, with seasonally dependent settings of storage, production flow etc. S-HYPE also includes some artificial water transfers between catchments Last updated: Dec 20, 2023

, lakes and ice. In the model the atmosphere is divided into a 3-dimensional grid, across the surface and upwards. To get good results processes outside the entire atmosphere must be considered, that is around the globe and up in the air. Such models are called global climate models.

As an example, Figure 1 presents the time of maximum precipitation intensity during the diurnal cycle around Lake Victoria (Africa’s greatest lake) from observations and from different model simulations.
