“…We conclude that the atmospheric circulation patterns have enhanced the gap of the maximum and minimum temperature and were the physical mechanisms for the extreme cold/warm events in the past decades. These results are consistent with previous studies in most parts of East Asia [38,43,45,[60][61][62], including the YRB of China [4,63].…”

Since there are many destructive effects caused by extreme climate events in the Yellow River, it is of great theoretical and practical significance to explore the variations of climatic extremes in this key basin. We used a meteorological dataset from 66 stations within the Yellow River basin (YRB) for the period 1960–2017 to calculate magnitude and frequency of precipitation/temperature extremes. We also analyzed the relationships between the main large-scale atmospheric circulation patterns (ACPs) and precipitation/temperature extremes. The trends in precipitation extremes were nonsignificant, only a few stations were characterized by significantly increasing or decreasing anomalies; this indicates the precipitation intensity may have been strengthened, and the extreme rainfall duration appears to have been reduced during 1960–2017. The trends of magnitudes for “cold” extremes were larger than those for “warm” extremes, changes of trends in frost days were higher than those for summer days, and the trends in increasing warm nights were higher than those of warm days. The influence of the El Niño–Southern Oscillation (ENSO) and Arctic Oscillation (AO) on temperature extremes outweighed the influence of the North Atlantic Oscillation (NAO), Indian Ocean Dipole (IOD), and Pacific Decadal Oscillation (PDO) for the other extreme climate indices. The YRB might be at risk of increased extreme high temperature events, and more attention should be paid to this higher risk of extreme climatic events.

“…China is susceptible to climate change (Chen and Zhai 2017). It was reported that the frequencies of warm days and warm nights have increased at rates of 0%-3.0% and 0%-4.0% per decade, respectively, in almost the entire region of China for the period 1961-2015 (Shi et al 2018), while the intensities of warm extremes have shown an asymmetric change pattern in China (Zhou et al 2016, Shen et al 2018. Spatially, warm extremes became significantly warmer in South China, northwestern North China, northeastern Northeast China, eastern Northwest China and eastern Southwest China.…”

LETTERVariations in start date, end date, frequency and intensity of yearly temperature extremes across China during the period Abstract Frequent temperature extremes due to climate change have had serious effects on human society and the natural environment. Using a 0.25°×0.25°gridded Tmax (daily maximum temperature) and Tmin (daily minimum temperature) data set and 12 global climate models simulations from the sixth phase of the Coupled Model Intercomparison Project (CMIP6), we investigated variations in yearly temperature extremes in China during the past five decades with respect to four characteristics, namely, their start date, end date, frequency, and intensity. Results showed that the occurrence of nighttime extremes (the cold nights and warm nights) responded strongly to climate change. For 1961-2017, cold extremes started later (3.25 d/decade) and ended earlier (−4.58 d/decade), with decreased frequency (−6.56 d/decade), especially for cold nights, and weakened intensity (0.14°C/ decade). In the same period, warm extremes started earlier (−3.43 d/decade) and ended later (3.15 d/ decade) with increased frequency (6.79 d/decade), especially for warm nights, and enhanced intensity (0.09°C/decade). The spatial pattern of the variations was complex with anomalous regions. Multimodel ensembles (MMEs) from CMIP6 agreed well with observations regarding the average trends of temperature extremes over China, although detailed changes in spatial pattern were not captured adequately. The hazards of temperature extremes deserve close attention in the future due to the complex changes likely to occur across China for various characteristics of these temperature extremes under conditions of climate change.

“…Precipitation and air temperature are important indicators of climate change [7,8]. For example, global surface precipitation has increased by approximately 2% during recent decades [9], while global surface air temperature has increased by 0.85 • C since preindustrial times [10]. Changes in air temperature and precipitation vary widely on regional and global scales because of regional differences in natural resources [11,12].…”

Climate change poses potential challenges to sensitive areas, such as high-elevation regions. The Yarlung Zangbo River (YLZR) basin is located in the southeast of the Qinghai-Tibetan Plateau. It contains large amounts of snow and numerous glaciers that are vulnerable to climate change. Based on daily observational data at 17 meteorological stations in and around the YLZR basin during 1957–2015, the variability of precipitation, air temperature, and streamflow were analyzed. The nonparametric Mann–Kendall test, Sen’s slope estimate method, cross wavelet transform (XWT), and wavelet coherence (WTC) were used to identify the annual seasonal trends. the abrupt changes of precipitation and air temperature, and their associations with large-scale circulation. The results showed that the YLZR basin experienced an overall rapid warming and wetting during the study period, with an average warming rate of 0.33 °C/10 a and wetting rate of 4.25 mm/10a, respectively. Abrupt change points in precipitation and air temperature occurred around the 1970s and 1990s, respectively. The abrupt change points of three hydrological stations occurred around the late 1960s and the late 1990s, respectively. The precipitation, annual average temperature, and the streamflow of the three hydrological stations were negatively correlated with the Pacific decadal oscillation (PDO) and the multivariate El Niño-Southern Oscillation (ENSO) index (MEI), reaching a significant level of 0.05.
