“…From a nation‐wide perspective, the annual extreme precipitation over China exhibits an upward trend, although small trend has been observed for the annual total precipitation (Zhai et al , ; You et al , ; Wang et al , ). However, regionally, an increase in annual extreme precipitation has been reported in Northwest China (NWCH) (Zhang et al , ; Jiang et al , ), the middle and lower reaches of the Yangtze River valley (Qian and Lin, ; Dong et al , ), part of Southwest China (SWCH) (Li et al , ), and the coastal areas of South China (SCH) (Zhai et al , ), whereas decreasing trends have been observed over Northeast China (NECH) (Wang et al , ), North China (NCH) (Fan et al , ), and the Sichuan Basin (Wang and Zhou, ; Zhai et al , ). Obvious seasonal features of extreme precipitation may be further summarized as increasing trends across all seasons in NWCH, a significant increasing trend in the Yangtze River basin in winter and summer, and a decreasing trend in central and NCH in spring and autumn (Wang and Zhou, ; Zhai et al , ; Wang et al , ).…”

ABSTRACT:The regional features of long-term changes in total and extreme precipitations over eight China domains and their seasonality and relationships with large-scale and local atmospheric and oceanic factors are investigated. A newly compiled data set of 917 China stations from the China National Meteorological Information Center with strict quality control is analysed. Wintertime extreme precipitation has increased persistently in all China domains, together with an obvious wetting tendency except in North China. In spring, an increase in extreme precipitation is also seen except in South China, but total precipitation increases only in half of China. A 'northern drying and southern wetting' (NDSW) pattern is found over eastern China for both extreme and total precipitations in summer when precipitation increases significantly in Northwest China (NWCH). Different features are found in autumn when negative trends are found in most of the China domains for total precipitation (except in NWCH and the Tibetan Plateau) and half of the domains for extreme precipitation. Overall, the frequency of extreme precipitation plays a dominant role in determining the extreme precipitation trend compared to the intensity of precipitation. The long-term changes in total precipitation and extreme ratio (extreme precipitation to total precipitation) are both strongly linked to the sea surface temperatures (SSTs) from the Indian Ocean to the Maritime Continent, the Kuroshio, the central-eastern Pacific, and part of the Atlantic Ocean. In summer, the NDSW pattern is closely associated with the weakening of East Asian monsoon circulation and the increase in land surface temperature of 40 ∘ -60 ∘ N. Local warming trends also contribute to the trends of extreme ratio in several domains in particular seasons.

“…In addition, a series of soil conservation practices (SCP) have been implemented to reduce soil erosion (Huang and Zhang, 2004;Wang et al, 2006;Yang et al, 2008). The annual precipitation has also changed significantly in many sub-basins of the YRB (Xu et al, 2009a;Dong et al, 2011;Wang et al, 2012). As a result, significant changes in streamflow were observed in the YRB (Wang et al, 2006).…”

a b s t r a c tFlooding in the Yellow River basin (YRB) has changed significantly over the last few decades because of climate change and human activities. Determining how the flooding changed and identifying the main driving factors of flood change is crucial to flood risk assessment and water resources planning. However, few studies have been conducted, especially in the whole YRB. To fill this gap, we investigate the spatial and temporal change of the annual maximum flood (AMAXF) in the YRB using observed data from 32 key hydrological stations (including 15 mainstream stations and 17 tributary stations). The ManneKendall test combined with trend index method is used to evaluate the trend in precipitation and AMAXF. The trend results indicate the AMAXF over the whole basin is dominated by decreasing trends: 72% of the stations exhibit significant decreasing trends (at 0.1 significance level) and 22% of the stations show no significant decreasing trends in the AMAXF. Both flood trends and abrupt change time exhibit obvious regional differences: the flood decreases is more pronounced in the midstream basins than in the headwater of the basin; the abrupt changes mainly occurred in the early 1990s for the upper reaches, and in the late 1990s for the middle reaches. To investigate the causes of flood change, the trends of precipitation extremes are analyzed in relation to the trends of peak floods. The analysis reveals that the decreasing precipitation extremes only results in the AMAXF reduction in the upstream basin. The decreasing AMAXF in the midstream and downstream of the basin are mainly attributable to the impacts of human activities (mainly including dam construction and soil conservation practices). In general, anthropogenic impacts play an increasingly important role in the AMAXF changes in the YRB. According to the possible changes in forcing factors, the AMAXF over the whole basin is expected to further decrease in the near future. However, there are still large flood risks in the tributary basins due to the collapse of check dams caused by extreme storms.

“…As a result, the changes in both precipitation and temperature extremes are observed globally (Alexander et al 2006;Choi et al 2009;Goswami et al 2010;Haylock and Nicholls 2000;Hegerl et al 2004;Manton et al 2001;Moberg and Jones 2005;Moberg et al 2006;Tank et al 2006;Yan et al 2002). For monsoon China, the climate extreme events and their variances are analyzed systematically (Dong et al 2011;Du et al 2013;Fan et al 2012;Gong et al 2004;Hu et al 2012;Li and Wang 2012;Qian et al 2012;Su et al 2006;Tian et al 2012;Wang et al 2012;Xu et al 2011;Zhai et al 2005;Zhang et al 2011). In East China, the significant inter-decadal change of the precipitation extremes was detected over past 50 years , and more precipitation extremes occurred during past 20 years (1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009) (Li and Wang 2012).…”

In this study, the regional climate model of RegCM3 is applied to investigate the sensitivity of regional climate over China using four cumulus parameterizations, the modified Anthes-Kuo (AK), the Grell with Arakawa-Schubert closure, the Grell with Fritsch-Chappell closure, and the MITEmanuel (EM). The model was integrated over the period of 1982 to 2001 using the NCEP Reanalysis data NNRP2 as boundary conditions. RegCM3 coupled with various cumulus parameterizations is evaluated firstly as for its ability to represent regional climatology and climate extreme indices, and the results show that simulated regional climate in China is sensitive to the option of cumulus parameterizations. All the cumulus schemes produce a northward expansion of heavy rain area and an underestimation of surface air temperature. For precipitation, the AK scheme simulates relatively better magnitude, while the EM scheme has more reliable performance on the spatial distribution. RegCM3 can represent the spatial distributions of extreme indices for both precipitation and temperature, as well as their decadal trends irrelevant to the cumulus parameterizations. However, the model underestimates the consecutive dry days and overestimates the three extreme wet indices, with the EM scheme giving the worst result. Slight underestimations of extreme temperature indices are detected in all cumulus parameterization scheme runs. The shapes of probability distribution functions for extreme indices are correctly produced, though the probabilities of extreme dry and warm events are underestimated.
