The scientists at the University of Cape Town designed a method called SOMD to predict future rainfall patterns. They trained their model using past weather data to understand how the atmosphere responds to climate change. By studying historical records, they could estimate how often it would rain in the future between 2080 and 2100. Their technique helps them translate big global climate changes into local, smaller-scale actions using a fancy computer analysis. This method allows them to predict the number of rainy days in each month for the far-off years they are investigating. Ultimately, their work gives us an idea of how future rainfall might change as our world gets warmer.
