Unexpectedly, the secondary inorganic fraction in PM2.5 increased with an increase in the ambient RH, which is a meteorological parameter independent of anthropogenic activities, indicating the presence of a feedback mechanism driven by Henry's law and thermodynamic equilibrium. During haze episodes, simultaneously elevated RH levels and anthropogenic secondary inorganic mass concentrations resulted in an abundant ALWC. The condensed water could act as an efficient medium for multiphase reactions, thereby facilitating the transformation of reactive gaseous pollutants into particles and accelerating the formation of heavy haze. ALWC was well correlated with the mass concentrations of both nitrate and sulfate, indicating both nitrate and sulfate salts play key roles in determining ALWC. Coincident with a significant reduction in SO2 emissions throughout China, nitrates will become a dominant anthropogenic inorganic salt driving ALWC. Thus, the abundance of ALWC and its effects on the aerosol chemistry and climate should be reconsidered.</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:000427661200006</style></accession-num><notes><style face="normal" font="default" size="100%">&lt;p&gt;Fz5ugTimes Cited:1Cited References Count:60&lt;/p&gt;</style></notes><auth-address><style face="normal" font="default" size="100%">Peking Univ, Coll Environm Sci &amp;amp; Engn, State Key Joint Lab Environm Simulat &amp;amp; Pollut Con, Beijing 100871, Peoples R ChinaUniv Manchester, Ctr Atmospher Sci, Sch Earth &amp;amp; Environm Sci, Manchester M13 9PL, Lancs, England</style></auth-address></record></records></xml>
