Lack of water, floods, or crop losses: As a result of climate change, pronounced periods of drought and rainfall are occurring more frequently and more intensively all around the world, causing human suffering and major economic damage. The more precise seasonal forecasts for the coming months are, the more effectively these consequences can be mitigated. A research team from Karlsruhe Institute of Technology (KIT) has now been able to improve global forecasts using statistical methods so that they can be used on the regional level. The researchers describe the new approach and the economic benefits of seasonal forecasts in the journals Earth System Science Data and Scientific Reports.
