Recently, DESS Ph.D candidate Zijian Zhao published a paper online as the first author called “Influence of the West Pacific subtropical high on surface ozone daily variability in summertime over Eastern China” on Atmospheric Environment, with Associate Professor Yuxuan Wang. The paper estimated the impacts of West pacific subtropical high on surface ozone daily variability in summertime over Eastern China.
The West Pacific subtropical high (WPSH), as one of the most important components of the East Asian summer monsoon (EASM), is the key synoptic-scale circulation pattern influencing summertime precipitation and atmospheric conditions in China. Here we investigate the impacts of the WPSH on surface ozone daily variability over eastern China, using observations from recently established network of ozone monitors and meteorology reanalysis data during summer (June, July, August; JJA) 2014–2016 with a focus on 2014. An empirical orthogonal function (EOF) analysis of daily ozone variations reveals that the dominating eigenvector (EOF1), which contributes a quarter (25.2%) to the total variances, is a marked north-south contrast. This pattern is temporally well correlated (r = ?6?10.66, p
