摘要

本研究探讨了 1901-2020 年期间印度孔坎和果阿地区月度、季节、年度和十年尺度降雨量的时间变化。采用 Man-Kendall 和 t 检验法对降雨量数据进行了趋势分析。年降雨量数据呈明显增加趋势。年降雨量呈每年 32 毫米的明显增加趋势。在过去 120 年中，西南季风在康坎和果阿地区的降雨量呈明显增加趋势。从月度降雨量来看，6 月、8 月、9 月和 10 月降雨量呈明显增加趋势，1 月和 2 月降雨量呈明显减少趋势。在 120 年期间，1931-1960 年的降雨量最大。十年降雨量分析表明，在研究期间，每年观测到的降雨量偏多年份共有 18 个，偏少年份共有 15 个。

Temporal variations of Rainfall over Konkan & Goa during 1901-2020

This study examines the temporal variation of rainfall on monthly, seasonal, annual and decadal scale over Konkan & Goa, India during 1901-2020. Trend analysis of rainfall data is carried out by using Man-Kendall and t-test. A significant increasing trend has been observed in annual rainfall data. A significant increasing trend of 32mm/year is present in annual rainfall. Southwest monsoon showed significant increasing rainfall trends over Konkan & Goa during the last 120 years. On the monthly scale, rainfall indicate significant increasing trend during the month of June, August, September and October showed and significant decreasing trend during January & February. During the period of 120 year rainfall is highest in period of 1931-1960. Decadal rainfall analysis shows total 18 excess years and 15 deficit years observed annually over the period of study.
