Statistical and synoptical analysis of China’s carbon monoxide emission and transportation using satellite images

چکیده مقاله

Air pollution, one of the most hazardous environmental problems in urban space is closely associated with the climate conditions. Today, pollution in the metropolitan has become an important issue which requires the management to provide practical solutions to improve biological conditions. Thus, recognizing the relationship between synoptic systems and air pollutants will contribute greatly to solving the environmental issues and for future planning. Hence, the present research was carried out to analyze the statistical–synoptical aspects of China’s carbon monoxide (CO) emission and transfer during 2016–17. For this purpose, the number of pollutant days was extracted. Then, the synoptic patterns of pollutant days were analyzed using satellite images of CO concentration and mean sea level pressure. The results revealed that January and July periods, respectively, had the highest and lowest amount of CO in low- and high-pressure systems for the transfer of pollutant expansion. Also, based on the results, sub-tropical high pressure (STHP) was the main factor for CO transfer and compression of the western Pacific to the northern parts of the Pacific and the western coast of North America and Canada. The capability of absorption of low pressures and transfer of high pressures had a major role in lower atmospheric CO transfer of eastern and southeastern coasts of Asia to the Pacific Ocean regions. In terms of CO pollution, a correlation of 0.47 was, also, observed between two regions of China and the Pacific Ocean. © 2019, Springer Nature Switzerland AG.
