ClearMicroplasticsfrom Ocean Depths to Landfall: Typhoon-InducedMicroplastic Circulation in a Warming Climate
Researchers found that typhoons in eastern China dramatically increased atmospheric microplastic deposition rates (6,291-12,722 items/m²/d versus 48-779 post-typhoon), with marine air mass entrainment introducing greater polymer diversity and smaller dense particles such as PET and PVC, suggesting a feedback loop where microplastics influence ocean warming and typhoon intensification.
Plastic After an Extreme Storm: The Typhoon-Induced Response of Micro- and Mesoplastics in Coastal Waters

Microplastic Variations in Land-Based Sources of Coastal Water Affected by Tropical Typhoon Events in Zhanjiang Bay, China
Researchers analyzed the abundance, composition, diversity, and flux of microplastics from three estuaries and one sewage outlet in Zhanjiang Bay, China, before and after tropical typhoon events, finding a 3.6-fold increase in microplastic abundance from land-based sources following typhoons. The study links increased stormwater discharge during typhoons to elevated microplastic loading in coastal waters, highlighting how climate-driven extreme weather amplifies plastic pollution.

Researchers assessed how Typhoon Mangkhut in 2018 affected the deposition of marine debris and microplastics on Hong Kong beaches, finding that the typhoon significantly redistributed both macro-debris and microplastics, with exposed beaches accumulating more material than protected ones. The study demonstrates that extreme weather events are important drivers of microplastic deposition dynamics in coastal environments.

Chasing plastic storms: Assessing atmospheric microplastic deposition by a ‘pulse event’ of tropical storm Fiona in Eastern Canada
Researchers geospatially analysed atmospheric microplastic deposition during tropical storm Fiona, one of the most destructive storms on record for Eastern Canada, using a unique time series to track how the extreme weather event mobilised and redistributed anthropogenic microdebris across terrestrial, aquatic, and marine environments. The study found that extreme meteorological events represent a significant and undercharacterised pathway for concentrated atmospheric microplastic deposition over large areas.
Efficient transport of atmospheric microplastics onto the continent via the East Asian summer monsoon
Researchers discovered that the East Asian summer monsoon efficiently transports airborne microplastics from the ocean back onto land in southeastern China. The study estimated that up to 213 kilograms of microplastics per year are carried inland by monsoon winds originating from Vietnam, the Philippines, and Malaysia. This finding suggests that not all ocean-bound airborne microplastics end up in marine ecosystems, as monsoon patterns can redirect significant amounts back to terrestrial environments.
Typhoon-induced turbulence redistributed microplastics in coastal areas and reformed plastisphere community
Researchers studied how Typhoon Wipha affected microplastic distribution and the microbial communities living on plastic surfaces in coastal waters near Shenzhen, China. They found that the typhoon significantly increased microplastic abundance in surface water while decreasing it in sediment, suggesting storm turbulence resuspends settled particles. The typhoon also reshaped the plastisphere microbial community, indicating that extreme weather events can redistribute both microplastics and their associated organisms.
Impact of typhoon events on microplastic distribution in offshore sediments in Leizhou Peninsula of the South China Sea
Researchers studied how typhoon events redistribute microplastics in offshore sediments around the Leizhou Peninsula in the South China Sea. The study found that monsoon and typhoon conditions significantly altered microplastic distribution patterns, with polypropylene and high-density polyethylene dominating across seasons, demonstrating how extreme weather events can reshape contamination patterns.
Impacts of extreme weather events on microplastic distribution in coastal environments
Researchers conducted a year-long survey in Hong Kong to study how extreme weather events affect microplastic distribution in coastal environments. They found that typhoons and rainstorms dramatically increased microplastic levels, with abundance jumping 5 to 36 times higher after major storms. The study suggests that extreme weather is the primary driver of seasonal variation in coastal microplastic pollution, which has implications as these events become more frequent.
Breaking the coastal barrier: Typhoons convert estuarine mangroves into sources of microplastics to the ocean
Researchers studied how typhoons affect the ability of mangrove forests in the Shenzhen River estuary to trap microplastics. During calm conditions, mangrove sediments stored high levels of microplastics, but typhoons flushed out roughly 90% of those particles, turning mangroves from microplastic sinks into sources. The findings suggest that extreme weather events can dramatically reshape how microplastics move through coastal ecosystems.
Atmospheric microplastic transport and deposition to urban and pristine tropical locations in Southeast Asia
Researchers measured atmospheric microplastic deposition at urban and pristine sites in Malaysia across two monsoon seasons and found microplastics at all locations, including a remote tropical forest. Deposition rates ranged from 114 to 689 particles per square meter per day, with monsoon wind patterns influencing the transport of particles over long distances. The study demonstrates that atmospheric transport is a significant pathway for spreading microplastic contamination to even remote ecosystems in Southeast Asia.

Researchers used multimedia observations from both land and sea to quantify the transport efficiency of atmospheric microplastics from land to ocean, finding that atmospheric transport is an inefficient pathway for delivering land-sourced microplastics to marine environments compared to other transport routes.
Atmospheric deposition as a pathway for microplastic transport to the marine environment: Temporal variation and environmental factors
A year-long study in a South Korean coastal bay found that atmospheric dry and wet deposition delivers a measurable and seasonally variable load of microplastics to the marine surface, with wind speed, rainfall, and dust events driving the temporal patterns. This confirms that the atmosphere is a significant and often overlooked transport route for microplastics from land to ocean.

Researchers quantified atmospheric fibrous microplastic transport from land to ocean in the Asia-Pacific region using data from nine ocean cruises between 2018 and 2019, developing a global inventory of atmospheric microplastic input into marine environments. The study concluded that atmospheric deposition is a significant and previously underestimated pathway for inland microplastics to reach the ocean.
Hurricane transport of ocean-sourced microplastic in the North Atlantic
Researchers found that Atlantic hurricanes can pick up microplastics from ocean surface waters and transport them as airborne particles, depositing them far from their origin. This study reveals that extreme weather events are an important but overlooked pathway for spreading microplastic pollution to remote regions.

This review examined how extreme weather events like typhoons, monsoons, and floods transport microplastics from aquatic environments into agricultural soils. The study found that severe weather significantly increases the amount and variety of microplastics deposited on farmland through surface runoff, wind, and wave action, raising concerns about food safety as climate events become more frequent.

Researchers investigated microplastic emission characteristics during a rainfall event in Masan Bay, Korea, using time-weighted sampling in the Samhochoen stream to capture temporal variation in microplastic loads. They found that microplastic abundance peaked during early runoff stages and was strongly influenced by rainfall intensity, with polypropylene and polyethylene accounting for roughly 60% of detected polymers.
