摘　　要：为了对青岛地区暴雨的中长期预报提供参考依据,用45a的资料对青岛地区的暴雨进行了统计分析,发现青岛暴雨日的年际波动较大,最多17d/a,最少1d/a,平均8d/a,近几年有逐渐增多的趋势。暴雨出现时段高度集中,6月下旬至9月上旬占全年的82.4%,旬分布为双峰型;大暴雨和区域性暴雨多数集中在8月,分布均为单峰型。地形对暴雨日、大暴雨日的分布等有一定影响。青岛7月、8月两月暴雨特征有一定差异:7月多局部性暴雨,8月多区域性暴雨和大暴雨。Using the observations of 45 years, we analyzed the rainstorms statistically in Qingdao which is situated in the Shandong peninsula. It is found that the interannual variations in the rainstorm days are significant with the maximum 17 days and the minimum 1 day in one year and average 8 days per year. In recent years, the rainstorm days tend to increase. Rainstorms are highly concentrated primarily from the last ten days in June to the first ten days in September, which accounts for 82.4 % of the total rainstorms of a year, and the rainstorms are bimodal pattern in the annual circle. The severe rainstorms and regional rainstorms are even more concentrated almost in one month （August）, and the temporal variation is unimodal with the peak phase in mid-August. Topography influences the distributions of rainstorms and severe rainstorms to a certain degree. There are differences in the characteristics of rainstorms between July and August in Qingdao： more local rainstorms in July, and more regional rainstorms and severe rainstorms in August. These results are of important significances in the respects of the mid-long term rainstorm forecast in Qingdao.
