      摘要:

      近年來中國區(qū)域降水的極端化問題得到學(xué)術(shù)界的廣泛關(guān)注,有關(guān)研究也獲得了大量成果。但是,目前國內(nèi)外常用的高分辨率降水資料序列多從1951年左右開始,普遍缺少20世紀(jì)早期中國的逐日降水資料,對于近一百多年中國極端降水變化特征及其機(jī)理,目前還不清楚。基于多來源的1901—1950年原始觀測報(bào)表數(shù)字化逐日降水資料,補(bǔ)充先前未錄入的“無降水”和缺測數(shù)據(jù),研發(fā)質(zhì)量控制方案并開展質(zhì)量控制,補(bǔ)充錄入檢出的缺失和錯(cuò)誤數(shù)據(jù)并再次質(zhì)控,結(jié)合1951年以來的現(xiàn)代降水日值資料,建立中國60個(gè)城市站1901—2019年降水日值數(shù)據(jù)集。數(shù)據(jù)集評估結(jié)果顯示,早期中國東部地區(qū)的臺站較為密集,數(shù)據(jù)完整性和正確性較好,但中國西部的臺站數(shù)量少且完整性和正確性偏低。本數(shù)據(jù)集構(gòu)建的年總降水量累積值序列與已有的月降水量數(shù)據(jù)基本一致。基于該數(shù)據(jù)集,研究發(fā)現(xiàn)重慶站近百年來的降水未出現(xiàn)顯著的趨勢性變化。該數(shù)據(jù)集使后續(xù)分析研究中國極端降水的百年尺度長期變化特征成為可能。

      Abstract:

      In recent years, the change of extreme precipitation in China has received extensive attention, and related research has obtained a lot of results. However, the high-resolution precipitation data from the well-known datasets worldwide generally start around 1951 at present, lacking daily precipitation data in China in the early 20th century, so the characteristics and mechanism of extreme precipitation changes throughout China in the past 100 years are still unclear. Based on multiple sources of digital daily precipitation data from 1901 to 1950, through supplementing the previously unrecorded “no precipitation” and missing data, developing the quality control plans and carry out quality control work, filling in some missing and erroneous data, and combining the modern daily precipitation data since 1951, a dataset of daily precipitation was established for the past 119 years (1901-2019) of 60 city stations in China. The assessment results show that the stations in the eastern part of China are relatively dense, and the data integrity and correctness are better, but there are only a few stations in Western China and the integrity is low. The accumulated annual precipitation time series constructed by the dataset are basically consistent with the existing monthly precipitation datasets. Based on this dataset, it is found that there is no significant trend in precipitation and extreme precipitation at Chongqing station during the past 119 years, and the centennial long-term change characteristics of extreme precipitation in China can be further analyzed by using this dataset.

      Key words: Observed data, Daily precipitation, Hundred-year time series, Extreme precipitation, China
