Abstract

Analysis of Nile flood stages from A.D. 640 to 1921 reveals major episodes of low Nile discharge during the years 930 to 1070 and 1180 to 1350 and major episodes of high Nile floods during 1070 to 1180 and 1350 to 1470. Examination of Nile flood maxima and minima and comparison with water levels in Lake Chad reveal a correlation between high Nile discharge and greater rainfall in equatorial East Africa. There is also apparently a correlation between low Nile discharge and cold climate in Europe.

摘要

分析公元 640 年至 1921 年的尼罗河水位记录，显示出在 930 年至 1070 年和 1180 年至 1350 年期间，尼罗河出现了低水位的主要阶段，而在 1070 年至 1180 年和 1350 年至 1470 年期间，则出现了高水位的主要阶段。对尼罗河洪峰和枯水期的研究，并与乍得湖的水位进行比较，表明尼罗河高水位与赤道东非地区降雨量增加之间存在相关性。此外，尼罗河低水位与欧洲寒冷气候之间显然也存在相关性。
