| 摘 要： | 利用古代日记资料发掘历史气候信息是重建古气候的重要方法。根据南宋吕祖谦的《庚子辛丑日记》记录的金华(婺州)公元1180年和1181年5—6月份逐日天气记录,利用金华1954—2012年实测月雨量和雨日资料的统计规律,重建了1180年和1181年金华地区5—6月份梅汛期雨量,并结合《日记》反映的天气过程,确定了这2年金华的出入梅时间,结果表明1180年和1181年入梅较现代偏早,1180年5—6月份雨量比现代偏小,梅雨期略偏短,1181年则雨量偏大,梅雨期明显偏长。上述结论对这2年历史文献记载的旱涝灾情提供了直观的有力佐证。

| Abstract: | Discovering climatic information from ancient dairies is one of the most important methods for the reconstruction of historical climate. Based on the weather records in the Gengzi Xinchou Diary written by Lü Zuqian in AD 1180 and 1181 of Southern Song Dynasty,the duration and rainfall of Meiyu Flood Periods(from May to June)in these two years in Jinhua area are reconstructed with the statistical regularities from the precipitation data measured in 1954-2012. It is found that both the Meiyu onset dates(MODs)in 1180 and 1181 are earlier compared with the average MODs of nowadays;the precipitation from May to June and the duration of Meiyu Flood Period are a little smaller and shorter than average in 1180,and larger and longer than normal in 1181. The results provided intuitive,favorable evidences for the records of drought and flood disasters during the two years in historical documents. |
