Aerosol and Air Quality Research Show all Northeast Monsoon (NEM): November – March Drivers: Associated with the strong Siberian High pressure system and active cold surges. Impact: This is the major rainy season, especially for the east coast of Peninsular Malaysia, eastern Sabah, and western Sarawak. November and December often see the heaviest rainfall, sometimes causing catastrophic flooding and landslides. Southwest Monsoon (SWM): Late May – September Drivers: Controlled by the warming of the Northern Hemisphere, leading to heated air rising and being transported by southwesterly winds. Impact: Generally characterized by lower precipitation, fewer clouds, and "dry epochs". However, it can bring drier meteorological conditions that contribute to transboundary haze from biomass burning in neighbouring regions. Inter-monsoon Periods: Occurring in April and October/November, these transitional phases often feature heavy convective rainfall and thunderstorms, particularly in the afternoons. Climate Change and Environmental Trends Recent studies highlight shifting trends in monsoon intensity and their environmental consequences: Rainfall Variability: While annual rainfall shows a slight declining trend in some areas like Johor, extreme wet and dry years are becoming more pronounced. Coastal Erosion: The Northeast Monsoon acts as a primary catalyst for severe coastal erosion, with roughly 52% of the Peninsular coastline affected. Marine Debris: Monsoon-driven currents influence pollution; for instance, plastic accumulation on the Terengganu coastline peaks during the Southwest Monsoon. Fisheries: High seas during the NEM often hinder fishing operations for small boats, leading to a significant dip in landings. Future Projections Climate models (such as CMIP6 ) project a continuous rise in surface temperatures ( 3 | Feature | Northeast Monsoon | Southwest Monsoon
