“…In recent years, extreme weather and climate events, especially the precipitation extremes have received more and more attention because these events have tremendous societal impacts (Fischer & Knutti, 2015; Liu et al., 2019; Zaz et al., 2019). The frequency and intensity of extreme climate events are increasing but with obvious regional differences as reported from different research groups (e.g., Agel et al., 2015; Tank & Können, 2003; Wei et al., 2017; Zhai, 2005). In different parts of China, it is also found that warming extremes, intense precipitation events are increasing but the cold extremes and Typhoons are decreasing (e.g., Guan et al., 2011; Ning et al., 2015; Ren et al., 2011).…”
