摘要
利用通辽市9个站1961—2015年逐日降水资料,统计分析极端降水量、降水强度和年最大日降水量的空间分布特征和时间变化趋势。结果表明,通辽市极端降水量、极端降水强度和年最大日降水量近55a来没有明显增加或减少变化趋势,但存在明显的年代际特征;三者的空间特征基本相似,由南向北总体上呈高—低—高的分布特征;通辽市年降水总量主要来自极端降水量的贡献。
Based on the daily precipitation data of 9 stations in Tongliao from 1961 to 2015, the spatial distribution characteristics and temporal trends of extreme precipitation, precipitation intensity and annual maximum daily precipitation were analyzed. The results show that there is no significant increase or decrease in the extreme precipitation, extreme precipitation intensity and annual maximum daily precipitation in Tongliao in recent 55 years, but there are obvious interdecadal feature. All three have the same distribution characteristics of tall-low-tall from the south to the north. The contribution of the total annual precipitation in Tongliao mainly comes from extreme precipitation.
