“…Later, by applying the concept of regional analysis, Lin et al separated a rainfall into common component and local component, in the practices of precipitation frequency analysis for the NOAA Atlas 14 in the U.S. (Lin et al 2006;Bonnin et al 2012) as well as for the Taihu Lake Basin in China Wu et al 2015). Other studies abroad have also been done using the regional L-moments approach which is combing the regional analysis with the L-moments for rainfall frequency analysis (e.g., United Kingdom (Fowler et al 2010), Italy (Norbiato et al 2007), Norway (Hailegeorgis et al 2013)) and many regions of China (e.g., Guangxi (Chen et al 2014), Yangtze River Delta region (Yin et al 2016), Huaihe River Basin (Shao et al 2016), Jiangxi (Ding et al 2018;Liu et al 2018), Sichuan (Li et al 2019) and Xiamen (Shang et al 2019)). The research results indicated that the regional L-moments method is able to solve the problems related to identification of homogeneous regions, testing and selection of the best fitting distribution, as well as estimations of parameters and quantiles at places of interest.…”
