Future Projection of Precipitation Bioclimatic Indicators over Southeast Asia Using CMIP6

Precipitation is a key meteorological component that directly related to climate change. Quantifying the changes in precipitation bioclimate crucial planning climate-change adaptation and mitigation measures. Southeast Asia (SEA), home world’s greatest concentration of ecological variety, needs reliable monitoring such changes. This study utilized global-climate models from phase 6 coupled model intercomparison project (CMIP6) examine variations eight bioclimatic variables over SEA for two shared socioeconomic pathways (SSPs). All indicators were studied near (2020–2059) far (2060–2099) futures provide better understanding temporal their uncertainty compared historical period (1975–2014). The results showed high geographical variability precipitation-bioclimatic SEA. mainland would experience more than maritime region. multimodel ensemble (MME) an increase mean annual rainfall 6.0–12.4% most except Philippines southern will be relatively less wettest month (15%) driest (20.7%) SEA; however, quarter by 2.85%, while decrease 1.0%. seasonal. In addition, larger area month, making vary geographically.
