“…However, the target value for the protection of the human health, as defined by the Air Quality Directive 2008/50/EC, is still exceeded in large areas of Southern and Central Europe where high temperature and solar radiation occur in summer (European Environmental Agency, 2013). In Spain, there is an upward trend in O 3 concentration in the last decade (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012), which is in line with a decrease of NO x emissions and with an increase in surface solar radiation (Querol et al, 2014;Santurtún et al, 2015). On average for the 2010-2012 period, the O 3 target value was exceeded in 48 of the 135 Spanish air quality zones (close to urban and industrial areas, mainly in the center and south of the country and along the Mediterranean coast, Ministerio de Agricultura, Alimentación y Medio Ambiente MAGRAMA, 2013) leading to an exposition to O 3 concentration above the target value of 14.5% of the urban population (European Environmental Agency, 2014b).…”

“…With the gradual popularization of computer analysis and the increased sharing of data, synoptic weather classification has great practical value in a wide variety of research fields. For example, it has widespread applications in the field of analyzing weather patterns related to air pollution (Mcgregor and Bamzelis, 1995;Zhang et al, 2012;Santurtún et al, 2015).…”

Abstract. Regional air pollution is significantly associated with dominant weather systems. In this study, the relationship between the particle pollution over the Yangtze River Delta (YRD) region and weather patterns is investigated. First, the pollution characteristics of particles in the YRD are studied using in situ monitoring data (PM 2.5 and PM 10 ) in 16 cities and Terra/MODIS AOD (aerosol optical depth) products collected from December 2013 to November 2014. The results show that the regional mean value of AOD is high in the YRD, with an annual mean value of 0.71 ± 0.57. The annual mean particle concentrations in the cities of Jiangsu Province all exceed the national air quality standard. The pollution level is higher in inland areas, and the highest concentrations of PM 2.5 and PM 10 are 79 and 130 µg m −3 , respectively, in Nanjing. The PM 2.5 : PM 10 ratios are typically high, thus indicating that PM 2.5 is the overwhelmingly dominant particle pollutant in the YRD. The wintertime peak of particle concentrations is tightly linked to the increased emissions during the heating season as well as adverse meteorological conditions. Second, based on NCEP (National Center for Environmental Prediction) reanalysis data, synoptic weather classification is conducted and five typical synoptic patterns are objectively identified. Finally, the synthetic analysis of meteorological fields and backward trajectories are applied to further clarify how these patterns impact particle concentrations. It is demonstrated that air pollution is more or less influenced by high-pressure systems. The relative position of the YRD to the anti-cyclonic circulation exerts significant effects on the air quality of the YRD. The YRD is largely influenced by polluted air masses from the northern and the southern inland areas when it is located at the rear of the East Asian major trough. The significant downward motion of air masses results in stable weather conditions, thereby hindering the diffusion of air pollutants. Thus, this pattern is quite favorable for the accumulation of pollutants in the YRD, resulting in higher regional mean PM 10 (116.5 ± 66.9 µg m −3 ), PM 2.5 (75.9 ± 49.9 µg m −3 ), and AOD (0.74) values. Moreover, this pattern is also responsible for the occurrence of most large-scale regional PM 2.5 (70.4 %) and PM 10 (78.3 %) pollution episodes. High wind speed and clean marine air masses may also play important roles in the mitigation of pollution in the YRD. Especially when the clean marine air masses account for a large proportion of all trajectories (i.e., when the YRD is affected by the cyclonic system or oceanic circulation), the air in the YRD has a lesser chance of being polluted. The observed correlation between weather patterns and particle pollution can provide valuable insight into making decisions about pollution control and mitigation strategies.
