“…At the same time, there has been an insignificant decrease in regionally averaged consecutive wet days (CWD), Wet days (NW), very heavy precipitation days (R20), extremely heavy precipitation days (R25), very wet days (R95p) and extremely wet days (R99p), maximum 1-day precipitation amount (Rx1day) and maximum 5-days precipitation amount (Rx5days) the regional trends for these indices are À0.35, À0.48 day/ decade, À0.11, À0.25, À3.31, À2.84, À0.49 and À0.28 mm/decade, respectively. The distribution of positive and negative slopes in the area is extremely irregular, consistent with previous studies in other parts of the world (Easterling et al, 2000;Frich et al, 2002;Ramos and Martínez-Casasnovas, 2006; L opez-Moreno et al, Łupikasza et al, 2011;Ivanova and Alexandrov, 2012;Wang et al, 2013aWang et al, , 2013d. The spatial and temporal distributions of indices of climate extremes in monthly precipitation extremes also exhibit obvious differences.…”

“…You et al (2008) focused on annual extreme climate events on the middle and eastern Tibetan Plateau during 1961e2005 and ignored the relatively short observation period, monthly changes and the mechanism analysis. Wang et al (2013d) concentrated on changes in daily extremes of temperature and precipitation over the western Tibetan Plateau during 1973e2011. In addition, other studies primarily paid attention to the average precipitation (Yang et al, 2013).…”

“…Precipitation trends over the QTP recorded large regional differences from 1961-2001; increased trends were observed for most regions, especially in eastern and central areas, while the western areas exhibited a decreased trend [25]. However, some investigations on extreme precipitation only involved partial areas of the QTP [26][27][28][29], and precipitation extremes for the entire QTP separated from China have not been previously investigated in detail. Moreover, many studies have confirmed the impact of complex topography over the QTP on spatiotemporal variations of precipitation [30][31][32]; nevertheless, whether and what kind of topographical influence exists in relation to changes of extreme precipitation still needs further study.…”

Abstract:Although precipitation extremes exert a major influence on populations and the environment, trend analysis for the entire Qinghai-Tibetan plateau (QTP) has not previously been undertaken. In this study, meteorological data from 83 weather stations was used to analyze the temporal trends and spatial distribution of 10 extreme precipitation indices over the QTP during 1975-2014. The Mann Kendall test and Sen's slope estimator were used to determine significances and magnitudes of station trends. Spatially, stations recording increasing trends were mainly distributed in the southwestern, central and northern regions. Stations with decreasing trends were centered on the eastern and southeastern areas. Temporally, all indices had an increasing trend except for consecutive dry days (CDD) and consecutive wet days (CWD) during the study period. The contribution of extreme precipitation to total precipitation showed a significant increasing trend. These findings may be due to the complex interaction between the large-scale circulation and topography. In general, the changes of extreme precipitation indicated an enhanced tendency, with the frequency, intensity and amount of heavy precipitation increasing over time. Furthermore, altitude dependency of extreme precipitation does not exist in QTP, with topography effects on changes in precipitation extremes being more obvious in the higher elevation, flat, and hill stations.

“…Quality control of the data was undertaken using the RClimDex package developed by Zhang and Yang [30], a control package that has been previously applied to test climate data [31]. The RClimDex package enabled errors in the data to be eliminated, including errors in manual keying, daily maximum temperatures lower than daily minimum temperatures, and any identified outliers.…”

In order to examine temperature changes and extremes in the Beijing-Tianjin Sand Source Region (BTSSR), ten extreme temperature indices were selected, categorized, and calculated spanning the period 1960-2014, and the spatiotemporal variability and trends of temperature and extremes on multitimescales in the BTSSR were investigated using the Mann-Kendall (M-K) test, Sen's slope estimator, and linear regression. Results show that mean temperatures have increased and extreme temperature events have become more frequent. Annual temperature has recorded a significant increasing trend over the BTSSR, in which 51 stations exhibited significant increasing trends ( < 0.05); winter temperature recorded the most significant increasing trend in the northwest subregion. All extreme temperature indices showed warming trends at most stations; a higher warming slope in extreme temperature mainly occurred along the northeast border and northwest border and in the central-southern mountain area. As extreme low temperature events decrease, vegetation damage due to freezing temperatures will reduce and low cold-tolerant plants may expand their distribution range northward to revegetate barren areas in the BTSSR. However, in water-limited areas of the BTSSR, increasing temperatures in the growing season may exacerbate stress associated with plants relying on precipitation due to higher temperatures combining with decreasing precipitation.
