“…Yin et al: Links of climate variability in Arctic sea ice Hebei was significantly larger than that in other regions of China (Wang et al, 2006;Shi et al, 2015). Revealed by the datasets from Shangdianzi Station, the long-term trend of O 3 concentrations in North China indicated that the O 3 pollution underwent a significant increase in the period 2005-2015, with an average rate of 1.13±0.01 ppb yr −1 (Ma et al, 2016).…”

“…Over the past several decades, due to fast economic development, air pollution has been increasing in China (Chen, 2013;Watts et al, 2018). The major air pollution types in China are haze pollution (i.e., high-level fine particulate matter) in winter (Yin et al, 2015;Wang, 2018) and surface ozone (O 3 ) pollution in summer (Ma et al, 2016;Tang et al, 2018). Due to drastic air pollution control in China since 2013, haze pollution has been controlled in recent years (the environmental statistics unit of a statistics center in Peking University, 2018), appearing as a sharp decrease in fine particulate matter.…”

“…In 2013, a severe heatwave with a highest temperature of 41.1 • C, contributed to the high O 3 concentration in the Yangtze River Delta (Pu et al, 2017). The frequency of large-scale, extreme heat events is closely related to atmospheric patterns, such as the Eurasian teleconnection pattern (EU; Pu et al, 2017;Li and Sun, 2018) and aerosol effective radiative forcing (Liu and Liao, 2017). The winds from a polluted area also transport O 3 and its precursors downwind (Doherty et al, 2013).…”

Abstract. Summer surface O3 pollution has rapidly intensified in China in the recent decade, damaging human and ecosystem health. In 2017, the summer mean maximum daily average 8 h concentration of ozone was greater than 150 µg m−3 in North China. Based on the close relationships between the O3 concentration and the meteorological conditions, a daily surface O3 weather index was constructed, which extends the study period to the historical period before 2007 and the projected future. Here, we show that in addition to anthropogenic emissions, the Eurasian teleconnection pattern (EU), a major globally atmospheric teleconnection pattern, influences surface O3 pollution in North China on a timescale of climate. The local meteorological conditions associated with the EU positive phase supported intense and efficient photochemical reactions to produce more surface O3. The associated southerlies over North China transported surrounding O3 precursors to superpose local emissions. Increased solar radiation and high temperatures during the positive EU phase dramatically enhanced O3 production. Furthermore, due to the close connection between the preceding May Arctic sea ice (SI) and summer EU pattern, approximately 60 % of the interannual variability in O3-related weather conditions was attributed to Arctic sea ice to the north of Eurasia. This finding will aid in understanding the interannual variation in O3 pollution, specifically the related meteorological conditions.

In order to quantify air pollution effects on climate change, we investigated the climate response associated with anthropogenic particulate matters (PMs) by dividing fine PM (PM 2.5 , particle size ≤2.5 μm) and coarse particulate matter (CPM, particle size >2.5 μm) in great detail in this work, with an aerosol-climate coupled model. We find that the changes in PM 2.5 and CPM are very different and thus result in different, even opposite effects on climate, especially on a regional scale.The column burden of PM 2.5 increases globally from 1850 to the present, especially over Asia's southern and eastern parts, whereas the column concentration of CPM increases over high-latitude regions and decreases over South Asia. The resulted global annual mean effective radiative forcing (ERF) values due to PM 2.5 and CPM changes are −1.21 WÁm −2 and −0.24 WÁm −2 , respectively. Increases in PM 2.5 result in significant cooling effects on the climate, whereas changes in CPM produce small and even opposite effects. The global annual mean surface air temperature (SAT) decreases by 0.94 K due to PM 2.5 increase. Coolings caused by increased PM 2.5 are more apparent over Northern Hemisphere (NH) terrain and ocean at mid-and high latitudes. Increases in SATs caused by increased CPM are identified over high latitudes in the NH, whereas decreases are identified over mid-latitude regions. Strong cooling due to increased PM 2.5 causes a southward shift of the Intertropical Convergence Zone (ITCZ), whereas the Hadley circulation associated with CPM is enhanced slightly over both hemispheres, along with the weak movement of corresponding ITCZ. The global annual mean precipitation decreases by approximately 0.11 mm day −1 due to the increased PM 2.5 . Generally, PM 2.5 concentration changes contribute more than 80% of the variation caused by all anthropogenic aerosols in ERF, SAT, cloud fraction, and precipitation.
