摘要
为了加强对太行山区暴雨过程的认识,利用翻斗式自记雨量计对发生在2000年7月上旬、2004年7月中旬和8月上、中旬的三场暴雨过程进行了测定、分析。初步测得,最大1分钟降雨3mm,最大10分钟降雨17.5mm,最大30分钟降雨30.75mm,最大1小时降雨45.75mm;降雨量主要集中在降雨过程的中后期,在特大暴雨过程中尤为明显。这一暴雨过程特性为暴雨洪水灾害的防治增加了难度。
With tipping bucket and self-recording rain meter, the three heavy rainfall events, in the first ten days of July in 2000, in the middle ten days of July and in the first and middle ten days of August in 2004 in Taihaug mountain area, are monitored and analyzed. The monitored max rain intensity are 3mm in one minute, 17.5mm in ten minutes, 30.75mm in half an hour, 45.75mm in an hour. The rain density varied in time largely and had no clear characters. Rainfall mainly accumulated in the middle and latter period of a event, especially during heavy rain period.
