Trans-Pacific Air Pollution | Science - AAAS
2000年10月6日 · Research into the dynamics of long-range transport, deposition, and impacts of atmospheric pollutants in the Pacific region is only beginning. The nature, magnitude, and spatial distribution of the pollutants and their effects are largely unknown.
Relative Influence of Trans-Pacific and Regional Atmospheric …
The primary objectives of this research were to (1) measure the PAH and PAH derivative (NPAH and OPAH) concentrations on PM 2.5 in ambient air masses in the Pacific Northwest and (2) determine the relative influence of trans-Pacific and regional transport at a remote mountain site in the Oregon Cascade Range (Mt. Bachelor Observatory) and at a r...
Acceleration of oxygen decline in the tropical Pacific over the past ...
2016年5月16日 · Here we combine models of atmospheric chemistry, ocean circulation and biogeochemical cycling to test the hypothesis that atmospheric pollution over the Pacific Ocean contributed to the...
Air pollution measures for Asia and the Pacific
Air pollution in the Asia Pacific region is a major health risk which also has damaging impacts on economic growth, the environment, and agricultural crop yields. 92% of Asia and the Pacific’s population – about 4 billion people – are exposed to levels of air pollution that pose a significant risk to their health.
Deadly Pacific ‘blobs’ tied to emission cuts in China
2024年5月6日 · The Pacific heat waves occurred in a part of the ocean that previously seemed unresponsive to rising global temperatures, and they coincided with a pollution crackdown in China that between 2006 and 2017 pushed down emissions by as much as 70% for sulfur dioxide, which reacts in the atmosphere to form sulfate particles.
Unique impacts of strong and westward-extended western Pacific ...
2024年10月1日 · As a subtropical anticyclonic high-pressure system that typically forms over the northwestern Pacific Ocean in summer, the Western Pacific subtropical high (WPSH) affects meteorological conditions and ozone pollution in China.
Atmosphere teleconnections from abatement of China aerosol
We find that the rapid aerosol abatement in China triggers atmospheric circulation anomalies beyond its source region, driving a substantial mean surface warming in the NEP, which provides a favorable condition for extreme ocean warming events.
Air Pollution in the Asia-Pacific Region. A Joint Asian Pacific …
Mitigating the regional health impacts of air pollution will require attention to the leading sources of pollution within both the region and population of interest, which emphasizes the need to expand ground-level air quality networks, particularly in rural regions, and couple these with publicly available remote-sensing air quality data ...
2019‒2020 Australian bushfire air particulate pollution and
2021年6月10日 · During late 2019 and early 2020, Australia experienced one of the most active bushfire seasons that advected large emissions over the adjacent ocean. Herein, we present a comprehensive research on...
Intensification of Pacific storm track linked to Asian pollution
2007年3月27日 · The intensified Pacific storm track is climatically significant and represents possibly the first detected climate signal of the aerosol–cloud interaction associated with anthropogenic pollution. In addition to radiative forcing on climate, intensification of the Pacific storm track likely impacts the global general circulation due to its ...
