Abstract Air quality in Northern China has become a global hot spot issue due to series of air pollution events the recent years. In this study, five representative pollutants (PM 2.5 , SO 2 NO CO, and O 3 ) were employed reveal spatial temporal distribution China. Periodic decline PM from 2016 2018 indicated that control measures have achieved desired results. addition, PM2.5 was significantly positively correlated with ( p < 0.001), had negative correlations other four pollutants....
Abstract In this study, the two influence systems in a snowstorm that occurred January 2021 are analyzed using conventional observation, intensive snowfall observation data and NCEP-FNL 0.25°×0.25° analysis data. The results show that, first, westerly trough combined with surface convergence line sub cold front produces strong southern part of Liaodong Peninsula, then air moves southward into flow snowfall. When system has large water vapor flux, deep wet layer ascending motion, is...
