Abstract

In recent years, extreme rainfall and related disasters, including floods and landslides, have led to significant property damage and loss of life globally. Southeast Asia (SEA) is particularly impacted by these rainfall-driven events. This study reviews research development and approaches to understand the current status of monsoonal extreme rainfall in SEA, with the importance of the impacts of natural and anthropogenic factors. Natural factors, including the individual and combined effects of various climatic phenomena, such as Madden–Julian Oscillation (MJO), El Niño–Southern Oscillation (ENSO) and cold surges (CSs), have significant impacts on rainfall patterns. Anthropogenic factors, including emissions and changes in land use, also play a crucial role in producing extremes. This review identifies key challenges, such as the uncertainty in both available rainfall datasets and climate models, emphasising the needs for climate model improvement and better adaptation to complex regional climatic and geographical environments. The findings enhance understanding and response strategies to extreme rainfall events and mitigate the associated negative impacts.
