Abstract Atmospheric aerosols have been found to influence the development of planetary boundary layer (PBL) and hence enhance haze pollution in megacities. Previous works on aerosol‐PBL interaction were mainly based model simulation for short‐term cases; so far, there is a lack long‐term observational evidences. In this study, multiyear measurements reanalysis meteorological data, we give evidences its impact aggravation. We significant heating upper PBL with maximum temperature change...
Abstract. Black carbon (BC) has been identified to play a critical role in aerosol–planetary boundary layer (PBL) interaction and further deterioration of near-surface air pollution megacities, which referred as the “dome effect”. However, impacts key factors that influence this effect, such vertical distribution aging processes BC, well underlying land surface, have not quantitatively explored yet. Here, based on available situ measurements meteorology atmospheric aerosols together with...
Extreme wildfires threaten human lives, air quality, and ecosystems. Meteorology plays a vital role in wildfire behaviors, the links between climate have been widely studied. However, it is not fully clear how fire-weather feedback affects short-term variability, which undermines our ability to mitigate fire disasters. Here, we show primacy of synoptic-scale driving extreme fires Mediterranean monsoon regimes West Coast United States Southeastern Asia. We found that radiative effects smoke...
Abstract Low clouds play a key role in the Earth-atmosphere energy balance and influence agricultural production solar-power generation. Smoke aloft has been found to enhance marine stratocumulus through aerosol-cloud interactions, but its regions with strong human activities complex monsoon circulation remains unclear. Here we show that biomass burning aerosols strongly increase low cloud coverage over both land ocean subtropical southeastern Asia. The degree of this enhancement spatial...
Black carbon (BC) plays an important role in the climate system because of its strong warming effect, yet magnitude this effect is highly uncertain owing to complex mixing state aerosols. Here we build a unified theoretical framework describe BC's states, linking dynamic processes BC coating thickness distribution, and show self-similarity for sites diverse environments. The size distribution BC-containing particles found follow universal law independent core size. A new module established...
In recent years, nitrate plays an increasingly important role in haze pollution and strict emission control seems ineffective reducing China. this study, observations of gaseous particulate pollutants during the COVID-19 lockdown, as well numerical modelling were integrated to explore underlying causes nonlinear response mitigation nitric oxides (NOx) reduction. We found that, due less NOx titration effect transition ozone (O3) formation regime caused by emissions reduction, a significant...
Abstract Every spring, biomass burning (BB) plumes from the Indochina Peninsula (ICP) are transported downstream by specific synoptic weather processes, potentially influencing regional through radiative effects of BB aerosols. However, favorable patterns for transport toward inland China and how they interact with aerosols not fully understood. In this study, we identified three predominant processes associated evident plume southern over past 20 years. The first two—the low pressure...
Biomass burning (BB) is one of the largest sources trace gases and primary carbonaceous particles in global troposphere, posing great impacts on air quality regional climate. Accurate quantification BB emissions vital for assessing its environmental climate impacts. However, there are still large uncertainties current emission inventories due to poorly characterized rates under different combustion states. The fixed factor (EF) instead varying EF associated with efficiencies may be reason...
Wildfires pose a substantial threat to human lives, destroy infrastructure, disrupt economic activity, and damage ecosystem services. Weather climate conditions, including air temperature, humidity, wind, precipitation, play crucial roles in determining the intensity persistence of wildfires, as well dispersion transport smoke plumes. In turn, aerosols emitted from biomass burning are capable influencing meteorology via aerosol-radiation interaction or aerosol-cloud interaction. However,...
Abstract Though China's air quality has been improved in the past decade, haze still engulfs megacities winter with fast increasing secondary aerosol like nitrate. Given that and its precursors exhibit great vertical heterogeneity, we conducted airship measurements at Shanghai December 2017 to understand critical drivers for rapidly increased pollution. By integrating in‐situ observations model simulations, found cold front favors long‐range transport of pollutants, during which chemical...
Abstract Atmospheric new particle formation (NPF) is vital in climate and air pollution for its contribution to aerosols cloud condensation nuclei; however, a vertical understanding of NPF still limited. Here, simultaneous observations at two altitudes were conducted over the North China Plain. Despite high aerosol loading during cold season, frequently observed. The upper‐air increasingly intensive starts earlier as haze deteriorated, onset time gap could exceed 3 hr. To understand factors...
Abstract Although air quality in China has improved substantially over recent years, haze pollution events still occur frequently, especially the North Plain (NCP). Previous studies showed that typhoons are conducive to regional eastern China; however, underlying mechanism and quantitative understanding of typhoons' impact on remain unclear there. Here, based ground‐based satellite observations, reanalysis data, model simulations, we show northward approaching essential for autumn NCP....
Anthropogenic emissions were greatly constrained during COVID-19 lockdown in China. Nevertheless, observations still showed high loadings of fine particles (PM2.5) over northern China with secondary aerosols increasing by 15 μg/m3 yet a ∼10% drop light-absorbing black carbon (BC). Such chemical transition aerosol composition tended to make the atmosphere more scattering, indicated satellite-retrieved absorption optical depth falling 60%. Comparison between weather forecast and radiosonde...
Abstract East Asia features frequent dust storms and intensive anthropogenic emissions. The mixing of natural pollutants exerts complicated impacts on air pollution regional climate. Studies have focused chemical interactions the mixed pollution, while meteorological feedback influences atmospheric chemistry not been fully investigated. Here, a comprehensive study widespread storm its influence quality downwind was conducted by combining multiple observations modeling. We found that...
Abstract. Large uncertainties persist within current biomass burning (BB) inventories, and the choice of these inventories can substantially impact model results when assessing influence BB aerosols on weather climate. We evaluated discrepancies among emission by comparing carbon monoxide (CO) organic (OC) emissions from seven major regions globally between 2013 2016. Mainstream bottom-up including Fire INventory NCAR 1.5 (FINN1.5) Global Emissions Database version 4s (GFED4s), along with...
Abstract Interannual variability of tropical fire activity has been linked to the El Niño‐Southern Oscillation (ENSO). Here we analyze changes in and simultaneous weather related ENSO over Southeast (SEAS) Equatorial Asia (EQAS) quantitively evaluate contribution key meteorological variables variations for past decades. During seasons, large increases fires emerge Niño years, which greatly coincides with more fire‐susceptible conditions compared La Niña years. Moreover, exhibit a significant...
