“2006.8”特大暴雨个例分析及对青岛东北部沿岸地区的影响

Case Analysis of Torrential Rain in August 2006 and Its Impact on Coastal Area in the Northeast of Qingdao

2006年8月25-26日青岛市发生了一场较大暴雨,其中即墨市为特大暴雨。即墨市王村雨量站最大6 h降雨量为434.0 mm,为山东省有降水纪录以来的最大值。这次暴雨涉及范围广,强度大,局部分点地区雨量暴雨频率比较稀遇,为当地工农业生产、交通、沿岸养殖业及海岸工程造成了巨大的损失。本文从暴雨成因、时空分布等方面分析了本次特大暴雨的变化规律,对暴雨频率等进行了初步分析,并对暴雨洪水造成的经济损失进行了统计,对重新认识我省暴雨区域分布规律提供了宝贵的第一手资料。

Torrential Rain took place in Qingdao in 25-26th August 2006. It was extremely heavy in Jimo. The maximumrainfall measured as much as 434.0 mm within 6 hours at Wangeun Rainfall Station of Jimo, and it was the heaviest in the historical records. This torrential with its unusually heavy intensity gave impacts on a large area. At some local places, the total rainfall and the rain gust frequency became exceptionally serious, causing heavy loss to the local industry, agriculture, communication, marine farming, and coastal engineering. The paper analyzes its causation, the temperal-spatial distribution of rainfall, the other variability, and rain gust frequency.
