这项研究重建了历史月降雨量数据在苏门答腊岛，印度尼西亚，22年（1879-1900年）在荷兰殖民时代的24个观测站。文献研究是在印度尼西亚和荷兰的图书馆进行的，以收集Nederlandsch-Indië的一系列Regenwaarnemingen记录的气象数据，这些数据以前从未被重建或分析过。结果显示，西海岸（97°-103 ° E，3°N-4°S）的6个观测站有超过3000 mm yr−1的丰富降雨量，东海岸的10个观测站和巴里桑山脊以东的3个观测站的降雨量低于3050 mm yr−1。丰富的沿海降雨只出现在沿着西海岸，但没有出现在东海岸和巴里桑山脊以东。1888/89年的厄尔尼诺事件对南半球气候类型的六个站旱季（5月至10月）的降雨量影响不大。在1881年、1885年和1896年观测到了年旱季降水量的显著减少。当比较最北端的班达亚齐站（5.5°N，95.3°E）和东部海岸的孟加拉站（1.5 °N，102.1°E）1931-60年和1971-2014年的月度数据时，在整个上个世纪，6 - 12月和1 - 5月分别出现了明显的减少和增加。最近的厄尔尼诺现象导致苏门答腊岛降雨量减少和干旱，但印度洋偶极子对世纪后期的降雨量有很大影响。
This study reconstructed historical monthly rainfall data at 24 observation stations in Sumatera, Indonesia, for 22 years (1879–1900) during the Dutch colonial era. The literature research was conducted in libraries in Indonesia and the Netherlands to collect meteorological data recorded in a series ofRegenwaarnemingen in Nederlandsch-Indië, which have never been reconstructed or analyzed previously. The results showed that the six western coast stations (97°–103°E, 3°N–4°S) have abundant rainfall exceeding 3000 mm yr−1, and the 10 eastern coast stations and three stations east of the Barisan ridge obtained rainfall below 3050 mm yr−1. Abundant coastal rainfall appeared only along the western coast, but not in the eastern coast and east of the Barisan ridge. The El Niño events of 1888/89 had low impact on rainfall amounts during the dry season (May–October) at the six stations of the Southern Hemispheric climate type. A significant decrease in annual dry-season precipitation was observed in 1881, 1885, and 1896. When comparing monthly data for 1931–60 and 1971–2014 at the northernmost station Banda Aceh (5.5°N, 95.3°E) and the eastern coast station Bengkalis (1.5°N, 102.1°E), a noticeable decrease and increase occurred in June–December and January–May, respectively, throughout the last century. The recent El Niño events have resulted in a decline in rainfall and dry conditions in Sumatera, but the Indian Ocean dipole had much influence on the amount of rainfall in the late-nineteenth century.
