“…four seasons. In fact, several studies have drawn the same conclusion [17,19,24,25]. Liu et al [18] further indicated that trace precipitation events decreased abruptly starting in 1982 when the temperature started rising rapidly in China.…”

The long-term change of the whole spectra of precipitation intensity in China is examined using observed daily data recorded at 477 surface stations for the period from 1961 to 2008. The results show a spatially coherent decrease of trace precipitation despite different reduction magnitudes among the regions. For measurable precipitation, significant regional and seasonal characteristics are observed. In autumn, the whole measurable precipitation decreased over Eastern China (east of 98°E). In summer and winter, a significant increase of heavy precipitation and decrease of light precipitation are detected south of Eastern China. In Western China, measurable precipitation is found to have increased in all four seasons. Composite analysis reveals a quasi-linear relationship between increasing surface temperature and precipitation on a global scale. The responses of precipitation at different intensities to the increased temperature are distinct, with a significant spectra-shifting from light to heavy precipitation. Compared with precipitation over the ocean, the amplification of heavy precipitation over land is relatively less, most likely constrained by the limited water supply. The response of regional precipitation to global warming shows greater uncertainties compared with those on the global scale, perhaps due to interference by more complex topography and land cover, as well as human activities, among other factors. precipitation spectra, global warming, spatial scale, extreme precipitation, composite analysis Citation:Wu F T, Fu C B.

“…These studies concluded that widespread significant changes in temperature extremes are associated with warming, while the changes in precipitation extremes present much less spatially coherence compared with temperature change. For China, precipitation has increased by 2% and the frequency of precipitation events has decreased by 10% from 1960 to 2000 [B. Liu et al, 2005], mean minimum temperature has increased significantly and mean maximum temperatures display no statistically significant trend between 1950 and 1995 [Zhai et al, 1999].…”

Changes in daily climate extremes in the eastern and central Tibetan Plateau during 1961–2005

[1] Changes in indices of climate extremes are analyzed on the basis of daily maximum and minimum surface air temperature and precipitation at 71 meteorological stations with elevation above 2000 m above sea level in the eastern and central Tibetan Plateau (TP) during . Twelve indices of extreme temperature and nine indices of extreme precipitation are examined. Temperature extremes show patterns consistent with warming during the studied period, with a large proportion of stations showing statistically significant trends for all temperature indices. Stations in the northwestern, southwestern, and southeastern TP have larger trend magnitudes. The regional occurrence of extreme cold days and nights has decreased by À0.85 and À2.38 d/decade, respectively. Over the same period, the occurrence of extreme warm days and nights has increased by 1.26 and 2.54 d/decade, respectively. The number of frost days and ice days shows statistically significant decreasing at the rate of À4.32 and À2.46 d/decade, respectively. The length of growing season has statistically increased by 4.25 d/decade. The diurnal temperature range exhibits a statistically decreasing trend at a rate of À0.20°C per decade. The extreme temperature indices also show statistically significant increasing trends, with larger values for the index describing variations in the lowest minimum temperature. In general, warming trends in minimum temperature indices are of greater magnitude than those for maximum temperature. Most precipitation indices exhibit increasing trends in the southern and northern TP and show decreasing trends in the central TP. On average, regional annual total precipitation, heavy precipitation days, maximum 1-day precipitation, average wet days precipitation, and total precipitation on extreme wet days show nonsignificant increases. Decreasing trends are found for maximum 5-day precipitation, consecutive wet days, and consecutive dry days, but only the last is statistically significant.

“…The extreme precipitation and its ratio to mean precipitation have also enhanced remarkably in a large area of China, particularly in Northwestern and Eastern China (Zhai et al 2005;Bai et al 2007;Feng et al 2007;Wang et al 2012;Sun and Ao 2013;Wu et al 2015;Zhou et al 2016). Meanwhile, a decrease in rainy days has been observed over most regions (Zhai et al 1999(Zhai et al , 2005Liu et al 2005;Qian et al 2007;You et al 2008;Zhou et al 2016). …”

“…Up till now, there have been numerous researches into this issue and great progress has been made. For example, it has been well documented that there are significant upward trends in annual mean precipitation over Southwest, Northwest, and Eastern China and significant downward trends over central North and Northeast China during the past decades (Liu et al 2005;Yao et al 2008;Wang et al 2012;Wang et al 2017). The extreme precipitation and its ratio to mean precipitation have also enhanced remarkably in a large area of China, particularly in Northwestern and Eastern China (Zhai et al 2005;Bai et al 2007;Feng et al 2007;Wang et al 2012;Sun and Ao 2013;Wu et al 2015;Zhou et al 2016).…”

Autumn rain of West China is a typical climate phenomenon, which is characterized by continuous rainy days and large rainfall amounts and exerts profound impacts on the economic society. Based on daily precipitation data from 524 observation stations for the period of 1961-2014, this article comprehensively examined secular changes in autumn rain of West China, including its amount, frequency, intensity, and associated extremes. The results generally show a significant reduction of rainfall amount and rainy days and a significant enhancement of mean rainfall intensity for the average of West China during autumn (SeptemberOctober) since 1961. Meanwhile, decreasing trends are consistently observed in the maximum daily rainfall, the longest consecutive rainy days, the greatest consecutive rainfall amount, and the frequencies of the extreme daily rainfall, consecutive rainfall, and consecutive rainfall process. Further analysis indicates that the decreases of autumn rainfall and related extremes in West China are associated with the decreases in both water vapor content and atmospheric unstable stratification during the past decades. On the regional scale, some differences exist in the changes of autumn rainfall between the eastern and western parts of West China. Besides, it is found that the autumn rainy season tends to start later and terminate earlier particularly in eastern West China.
