“…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.

“…Though, there are still debates on the global warming hiatus, it is virtually certain that the warming hiatus were more noticeable in regional scales at the Northern Hemisphere (NH): for example, mainland China and Eurasian continents (Duan and Xiao 2015, Guan et al 2015, Li et al 2015, Garfinkel et al 2017, Sun et al 2017, Xie et al 2017, Shen et al 2018. Compared to the studies on the terrestrial warming hiatus, less focus has been given to warming hiatus at marginal seas.…”

Based on the satellite-derived global daily sea surface temperature (SST) data set with high resolution (0.25°by 0.25°), we analyzed changes in annual mean SST and extreme SSTs over the China Seas since 1982. Results show that the annual mean SST in the China Seas has experienced a remarkable declining trend during the global warming hiatus (1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013), which was dominated by the striking cooling of SST in boreal winter. Despite annual mean SST experienced warming hiatus after 1998, the regional averaged SST for 1998-2013 was still 0.5°C above that for 1982-1997. The statistical distributions show that there are not only significant warmer climate shift in annual mean SSTs but also in annual extreme hot SSTs and cold SSTs. These changes can increase the likelihood of extreme oceanic warming events, known as marine heatwaves (MHWs). Further analyses reveal that, from 1982 to present, the MHW frequency increases at a rate of 1.13 events per decade, 2.5 times the global mean rate. For the period 1998-2013, the MHWs in the China Sea has never decreased in both of the frequency and intensity but has already become more frequent, longer duration and more intense than those metrics of MHWs during 1982MHWs during -1997

“…Meanwhile, most areas west of 108°E or south of 30°N were characterized by continual warming, rather than by a decelerated warming trend (Figures and ). It is likely that an increase in dryness or a decline in warm season precipitation in the southern China (Li et al ., ; Shen et al ., ) as well as the radiatively forced temperature effect in the western China (especially on the Tibetan Plateau) facilitated this continual warming (Ma et al ., ). Additionally, more than half of stations were characterized by monotonic temperature increase, which might also be directly related to continuous warming at the country level (Risbey et al ., ).…”

“…In earlier work, Wang et al (2010) analysed meteorological records in China for the period of 1961-2004 and showed that the warming trend started around 1980 in most stations and that this phenomenon gradually occurred later from north to south. Nevertheless, through applying the period of global warming "hiatus" for a priori justification to regional scales (Chen and Zhai, 2017), several recent studies pointed out that China also experienced a warming "hiatus" since 1998 (Li et al, 2015;Xie et al, 2017;Shen et al, 2018). In different regions, a strong warming "hiatus" in eastern China was observed during 1998-2013 (Chen and Zhai, 2017), especially in Northeast China (Sun et al, 2017), whereas an accelerated warming trend was detected on the Tibetan Plateau over the same period (Duan and Xiao, 2015;Ma et al, 2017).…”

As the climate system is known to be warming unevenly, the open question of whether there has been a significant warming “hiatus” at global or regional scales has attracted worldwide attention. With annual mean air temperature (Tmean) setting new records subsequent to 2012, it is reasonable to reanalyse the presence of an apparent decelerated warming trend in China. We therefore examined the shifts of temperature trends in China between 1980 and 2017 using homogenized records from 798 meteorological stations via the Breaks For Additive Season and Trend (BFAST) method and Mann–Kendall and Sen's slope estimator statistical tests. The results show that Tmean at the country level exhibited monotonic increase with a positive break occurring around 1997, and the warming rate during 1980–2017 (0.36 °C/decade) was slightly higher than that during 1980–1997, which suggests that this positive break did not overwhelm the overall continuous warming trend. Spatial records show that most areas west of 108°E or south of 30°N within the country experienced a continual warming trend over the study period and that negative break that occurred around 2010 was major contributor to temporary decelerated warming trend detected in other areas, especially in Northeast China. Hence, this study highlights annual air temperature has continued to rise overall in China since 1980, while considerable regional differences have been detected within the shifts of temperature trends.
