Variations in the start, end, and length of extreme precipitation period across China

Abstract: Using the daily precipitation records during 1961–2013 from 686 meteorological stations across China and the atmospheric circulation indexes, this study investigates the spatio‐temporal changes in the occurrence time and length of the extreme precipitation period (EPP), as well as their influencing factors. The results show the following aspects: (1) In the last 53 years, the start dates of the extreme precipitation period (EPPS) generally advanced. The end dates of the extreme precipitation period (EPPE) are … Show more

“…The first phase in categorizing precipitation time series in accordance with the EEPs (Event-based Extreme Precipitation) is to set a threshold value that defines a precipitation event. Typically, 1 mm is the value considered as a threshold, used to categorize dry and wet days as very light precipitation amount (e.g., below 1 mm), which perhaps would have been ignored and noted as dry days in many cases [42,79,80]. Hence, an event containing more than 1 mm daily precipitation amount during consecutive days is well-defined as a precipitation event.…”

“…The CMIP5 model is driven by climate, so it is very important to establish climatic zones in the research area. Numerous studies on precipitation in China have been performed based on geographical location or watershed zoning [22,42,43]. Therefore, according to the precipitation characteristics in China, four climatic zones were established for the comparison and projection of extreme precipitation.…”

“…To reflect the extreme temperature and precipitation in multiple aspects, 14 extreme climate indices recommended by the ETCCDI were employed in this study ( Table 3 ), including seven extreme temperature indices (the diurnal temperature range (DTR), the numbers of summer days (SU), the number of ice days (ID), the highest daily maximum temperature (TXx), the lowest daily minimum temperature (TNn), the warm spell duration index (WSDI), and the cold spell duration index (CSDI)) and seven extreme precipitation indices (the highest 5-day precipitation (Rx5day), the extremely wet-day precipitation (R99pTOT), the heavy precipitation days (R20mm), the total wet-day precipitation (PRCPTOT), the precipitation intensity (SDII), the consecutive dry days (CDD), and the consecutive wet days (CWD)) [ 20 , 21 , 40 , 66 , 67 , 68 , 69 , 70 ].…”

“…The Rx5day and CDD indices can also be applied to evaluate potential floods because persistent heavy rainfall promotes the occurrence of floods and subsequent landslides [ 71 ]. These indices can also be classified into four categories: absolute indices, threshold indices, percentile indices, and duration indices [ 69 , 72 ]. The nonparametric Mann-Kendall trend test is applied to establish whether the trends of these indices are significant [ 73 ].…”
