“…As a consequence, ENSO may trigger extreme hydroclimatological events of floods, droughts, and cyclones of different phases (e.g. Zhang et al, 2007;Gemmer et al, 2008;Jiang et al, 2009;Yu et al, 2012). This may explain opposite correlations, seen in winters of 2009 (Figs.…”

“…In Romania, there was a significant upward trend in moderate and heavy precipitation events but a predominantly downward trend in the number of days with precipitation (Croitoru et al, ). Maximum daily precipitation showed an upward trend in southern river basins in China but a downward trend in northern river basins (Chen et al, ). In Arab states, consistent warming trends have strengthened since the early 1970s, concurrent with an increase in extreme precipitation events (Donat et al, ).…”

Extreme climate events affect sustainable development in many parts of the world. Although several studies of local extreme climate events exist, such events need more thorough investigation. Detailed studies of climatic variations that assess changes on both spatial and temporal scales are becoming increasingly necessary. In this study, 14 indices for extreme temperature and 12 indices for extreme precipitation were used to analyze the spatial distribution and temporal trends of extreme climate events in the three‐rivers headwater region (TRHR), China, over the past five decades. We found that the frequency of high temperature extremes has increased, whereas the frequency of dry extremes has decreased. Statistically significant upward trends emerged for the number of warm nights (TN90p) and the number of warm days (TX90p) in the TRHR, which increased at a rate of 11.75 and 6.79 days/10 years (p < 0.05), respectively. We also found a highly significant downward trend in the number of consecutive dry days with a rate of −4.05 days/10 years across the whole region. Overall, the TRHR has become warmer and wetter over the past 50 years and the frequency of extreme events has increased. Wavelet analysis indicated that there are significant relationships between extreme climate events in the TRHR and large‐scale ocean‐atmosphere circulation patterns, for example, the Pacific Decadal Oscillation and the El Niño–Southern Oscillation. Our findings will help local water managers and stakeholders ensure that there are effective measures in place to adapt to and mitigate the effects of potential future climate change in the TRHR.

“…Precipitation extremes are one focus in studies over basins in China. Chen et al studied precipitation extremes in large basins across China [12] and, similarly, studies were also performed in the Yangtze River [13], Pearl River [14,15], Lancang River [16], and Yellow River [17]. Zhang and Cong analyzed the mean intensity and frequency of precipitation events in large river basins across China from 1956 to 2005.…”

Based on a high-quality dataset of 713 daily precipitation series, changes in daily precipitation events during 1960-2013 were observed in China's ten largest river basins. Specifically, the amount of precipitation in four categories defined by fixed thresholds and their proportion on total precipitation were analyzed on annual and seasonal time scales. Results showed annual precipitation increased by 1.10 mm/10yr in China, but with obvious spatial differences. Regionally, annual precipitation increased significantly in northwestern rivers, upstream areas of the Yangtze River, the Yellow River, southwestern rivers (due to increase in light and moderate precipitation); and in southeastern rivers, downstream areas of the Yangtze River, and the Pearl River (due to increase in heavy and extreme precipitation). Annual precipitation decreased significantly in the mid-Yangtze River and upstream Pearl River (due to decrease in light, moderate, and heavy precipitation). Seasonally, precipitation decreased only in autumn; this was attributable to a decrease in light and moderate precipitation. Results show that the distribution of precipitation intensity over China has shifted to intense categories since the 1960s, there has been an increase in moderate precipitation in Northwestern and Northern China, and an increase in extreme precipitation in Southeastern China. This shift was detected in all seasons, especially in summer. Precipitation extremes were investigated in the categories of extreme precipitation and results show that the risk of flood has been exacerbated over the past half-century in the Huaihe River, the mid-and lower Yangtze River, the Pearl River, and southeastern rivers.
