“…5. They further attempted to trace the wave train back to an origin in the lower stratosphere over the North Atlantic, as was suggested by Park et al (2014), but could not find sufficient evidence. We could not identify a stratospheric origin either.…”

“…Previous researchers tried to depict the atmospheric model of cold wave from different points of view (Lefevre, 1989;Park et al, 2014). By investigating the observed time series of storm surge and referring to Zhao and Jiang (2011), an artificially constructed wind field is employed in different sensitivity studies of Section 4.…”

“…However, it also exhibits significant intra-seasonal variability. An episodic expansion of the Siberian High deep into southern China often causes a cold surge in East Asia (Compo et al, 1999;Garreaud, 2001;Park et al, 2013). Such an expansion of continental high-pressure system, along with migrating low-pressure systems in northern China has been considered to be a dominant pathway driving Asian pollutions 25 off the continent.…”

“…As shown later, inspection of daily variations of Aerosol Optical Depth (AOD) and NO 2 column density from satellite images, hourly 25 variations of AOD, NO 2 vertical column density, and PM distributions from chemistry transport model, and surface weather map analyses reveals that the strength and location of anticyclonic systems over southern China (usually expanded from the Siberian High) and those of cyclonic systems over Manchuria (initiated by Altai-Sayan cyclogenesis) are the two major components that determine regional pollutant transport patterns. Objective clustering analyses in the previous studies Kim et al, 2014;Lee et al, 2011;Park et al, 2013) are also carefully considered. Kim et al (2005) used cluster 30 analysis of HYSPLIT backward trajectories arriving at the Gosan site in Jeju island, Korea, to classify five pollutant transport patterns.…”

Abstract. We demonstrate that daily pollutant transport patterns in East Asia are visible from satellite images when 15 inspected with corresponding synoptic weather analyses. Transport pathways of air pollutants in East Asia are investigated using satellite observations, surface weather charts, and chemical-transport model simulations. It is found that during cool season (fall to spring), pollutant transports in East Asia are largely determined by synoptic weather patterns associated with high pressure system over southern China, which is extended from the Siberia High, and low pressure system over Manchuria, which is initiated by Altai-Sayan cyclogenesis. Based on the relative location and strength of these weather 20 systems, three types of synoptic weather patterns that may contribute to pollutants transport in East Asia, especially in China and Korea, are identified: i.e., (1) a strengthening of the Siberian High and its southeastward propagation; (2) a high-pressure system over southern China followed by a frontal passage associated with a northern low-pressure system; and (3) a stagnant high-pressure system over southern China. For all three patterns, the high-pressure system in southern China is essential for the development of regional air pollution, while frontal activities associated with low-pressure system provide a forcing 25 mechanism to transport those pollutants eastward or southeastward. Observed and simulated surface PM distributions show good agreement in both aerosol optical depth and NO2 column density further implying that anthropogenic emissions also contribute to regional events of high surface PM concentrations. It is argued that the quasi-periodic migration of synoptic weather systems in East Asia works as an efficient pump of pollutants; i.e., regional air pollutions developed under highpressure systems are transported downstream by low-pressure systems. 30
