摘要
根据黄石市3个国家气象观测站1973—2019年的降水量资料,采用线性倾向估计、M-K突变检验和异常分析方法对近47年来黄石市降水变化特性进行分析。结果表明,近47年来黄石市年降水量呈不显著的上升趋势,2001—2010年的年降水量明显偏少,2011—2019年的年降水量恢复到20世纪90年代水平;降水量主要集中在春季和夏季,春季和秋季降水量均呈现出波动下降趋势,夏季和冬季降水量均呈波动上升趋势。近47年来黄石市没有出现降水异常偏多年和降水异常偏少年。
Based on the precipitation data of Huangshi from 1973 to 2019,the variation characteristics of precipitation in Huangshi during the past 47 years were investigated using linear tendency analysis,M-K mutation test and anomalous analysis.The results show that the annual precipitation in Huangshi during the past 47 years exhibited an insignificant upward trend;the precipitation in the 2000s was obviously less,and the precipitation in the 2010s improved to the value in the 1990s.The precipitation in Huangshi during the past 47 years mainly concentrated in spring and summer;the precipitation in spring and autumn showed a downward trend,while the precipitation in summer and winter showed an upward trend.There were no anomalous plenty and deficient rainfall years during the past 47 years in Huangshi.
