“…According to quantitative analysis, in China, precipitation and extreme precipitation have increased by approximately 10% and 23%, respectively, for each increase of 1 • C in surface temperature [33]. Although precipitation changes such as a decreased frequency, increased intensity, and greater occurrence of extreme precipitation have been observed [8,34,35], some gaps remain in our understanding of how precipitation changes under global warming. To obtain a more complete picture of how precipitation changes in China, examining other precipitation characteristics is crucial as it enables us to detect any alteration in precipitation patterns and obtain additional information about precipitation variations in China.…”

“…According to the Clausius-Clapeyron equation, for every 1 • C rise in temperature, there could be an approximate 7% rise in precipitation, due to increased humidity-holding capacity in the atmosphere [6]. Changes in precipitation show clear regional characteristics [7,8], resulting in distinct disasters in different climatic regions and posing major challenges to socio-economic systems, but these have not yet been fully understood.…”

Variations in precipitation have a great influence on human society and the natural environment. Existing studies have provided substantial information regarding variations in the magnitude, frequency, and intensity of precipitation. However, little is known about how the start and end dates of precipitation change, which could offer crucial insights for related studies in agriculture, hydrology, and other related disciplines. Here, we present an analysis of variations in the start date, end date, and frequency of different precipitation intensities, using a widely used gauge-satellite-reanalysis-based merging product, during the latest period, 1980–2022, across China. The results show that the spatial–temporal variations in the start date, end date, and frequency of different precipitation intensities were complex among regions. For example, in northeast and northwest China, light precipitation (LP) started earlier and increased in frequency during the study period. In the Tibetan Plateau, precipitation at different intensities levels started earlier, heavy precipitation (HP) and violent precipitation ended earlier, and the frequency of LP and moderate precipitation increased significantly. The start date of HP shifted earlier in Southeast China (−0.28 days/year). Our findings could be helpful in providing a comprehensive understanding of precipitation changes under global warming and highlight the need to pay close attention to these precipitation changes in the future.

“…Affected by terrain, the precipitation (including extreme precipitation with different duration) over the SCB exhibits a significant diurnal feature (M. G. Wu & Luo, 2019; Zheng et al., 2019), which usually begins at night, peaks between midnight and early morning, and gradually ceases after sunrise (S. Chen et al., 2019; J. Liu et al., 2021; Y. Wu et al., 2018; Zhao et al., 2020; L. Zhu et al., 2018). In recent years, the frequency/intensity of extreme precipitation (especially hourly extreme precipitation) has considerably increased over the SCB (Deng et al., 2022; Han et al., 2019; Lei et al., 2022; L. Li et al., 2020; X. Li et al., 2022; Park & Min, 2017). Previous studies show that the extreme precipitation over the SCB is shaped by the complex terrain (Hu et al., 2021; C. H. Huang et al., 2022; Nie & Sun, 2021; Y. Zhang et al., 2021).…”

The roles of the Tibetan Plateau (TP) and Yunnan‐Guizhou Plateau (YGP) in regional precipitation extremes over the Sichuan Basin (SCB) in summer under specific circulation background remain unclear. This study quantifies the impact of TP or YGP on the regional extreme precipitation event (REPE) which occurred during 04:00 Beijing time (BJT) on 11 August to 03:00 BJT on 13 August 2020 with a rainfall center located in the western SCB based on numerical experiments. Results show that the accumulated precipitation regionally averaged over the western SCB during the REPE can be reduced by 84% (51%) when the TP (YGP) is absent, and the decreased precipitation is mainly caused by the reduced stratus precipitation. Mechanism analysis indicates that relative to the control experiment including the TP and YGP, the absence of TP or YGP leads to reduced temperature over the SCB induced by anomalous cold advection from the upstream regions where the terrains are removed, and further results in much more stable stratification and thereafter weakens the ascending motions and reduces the stratus precipitation over the western SCB. On the other hand, the absence of TP or YGP induces an anomalous anti‐cyclone at 850 hPa over SCB, which further weakens both the uplift effect of terrain on airflow along the windward slope and water vapor transport over the western SCB and thereafter reduces the precipitation over this region. This study deepens the understanding of the topographic effect on regional extreme precipitation over SCB in summer from the thermodynamic and dynamic processes.

Under global warming, a notable intensification of precipitation extremes has posed significant threats to both natural ecosystems and human societies. However, there is still a lack of systematic studies on the variability of hourly precipitation extremes and a comparison with daily precipitation extremes. This study introduces a set of indices for hourly and daily precipitation extremes to systematically examine the changes across eastern China during the summers from 1980 to 2020. The results show that southern China is the sensitive regions with a notable large value of climatology in frequency and intensity for both of hourly and daily precipitation extremes. For the trends, the frequency of hourly precipitation extremes shows a rising trend in southern China, and intensity increased in northern China. Conversely, for daily precipitation extremes, the enhanced intensity and frequency are observed only in southeastern China. Additionally, the eastern coastal area experiences prolonged hourly rainfall with increasing persistence, while the region with an increased duration of daily precipitation is situated further south. Comparing the periods 1980–1999 and 2000–2020, precipitation extremes shift toward more intense and more frequent, with more pronounced variations at the hourly scale. Notably, northeastern China tend to be more intense and shorter‐lived hourly precipitation extremes after 1999, while south China experiences more frequent and longer‐lasting extremes. These changes are partly attributed to the increased unstable conditions, enhanced convective available potential energy and weakened convective inhibition.
