Future Climate on a Regional Scale

Accurate regional climate predictions are crucial for effective adaptation and planning. In Beni region (DRC), the climate normal for mean temperature is 22.36°C, while for annual rainfall it is 1673.689 mm. Significant changes in mean temperature and rainfall patterns are revealed by the Mann Kendall Test and Sen's Slope, including decreased rainfall in April, October, and November, and increased mean temperature in January, February, May, June, September, October, and December.From the SDSM model, projections indicate decrease in rainfall by the end of the century across all RCPs, except for August and December, with expected reductions in annual rainfall ranging from 348.604 mm to 610.035 mm. Month-to-month temperature fluctuations indicate higher mean temperatures in January, June, July, October, and December, with a 1.37°C increase in June, while the remaining months will experience decreasing temperatures, with August having the lowest value at -0.92°C. By 2100, it is projected the mean annual temperature ranging from 22.40°C to 22.43°C.
