“…The prevailing monsoon climate results in a strong northerly wind of 5.5 m s −1 during winter and a southeasterly wind of 5.0 m s −1 during summer (Zhu et al, 2015). Saltwater intrusion in the Changjiang estuary is also mainly determined by river discharge and tides (Song and Mao, 2002;Gu et al, 2003;Shen et al, 2003;Luo and Chen, 2005;Qiu et al, 2012;Chen et al, 2019a) but is also influenced by wind (Xue et al, 2009;Li et al, 2012;Ding et al, 2017;Zhang et al, 2019) and topography (Li et al, 2014;Chen et al, 2019b). The impact of wind on saltwater intrusion has been studied but only with a climatic wind (Xue et al, 2009;Qiu et al, 2012;Chen et al, 2019a) and a strong northerly wind induced by ordinary cold fronts in winter lasting 1-2 d, which could cause a change in the observed salinity (Li et al, 2012).…”
