Changes in consecutive dry/wet days and their relationships with local and remote climate drivers in the coastal area of China

Being located between Eurasia continent and the western Pacific Ocean, coastal area of China (hereafter as CAC) is vulnerable to climate change prone climate-related disasters. Based on daily meteorological dataset 156 stations, variations consecutive dry days (CDD) wet (CWD) their relationships with local remote drivers from 1961 2017 over CAC were investigated. Results showed that multi-year averages in CDD CWD 22.5–93.7 3.4–11.8 days, generally presenting a “high north low south” “low high spatial pattern, respectively. The decadal trend rates − 4.5–2.7 0.7–0.6 per decade, respectively, both showing universal insignificant trends CAC.
