摘要:
根据苏州境内常熟、枫桥、平望3个雨量站1988—2017年降雨资料,对应苏州区域分析了降雨年际变化特点,并从3个时段段分析苏州市降水量月度、季节分布规律。结果表明:苏州市在所研究时段内,降水量呈较明显上升趋势,多年平均中部最大,南部次之、北部最小,降水量呈从苏州中部向南北两侧降低趋势; 降雨月度分布主要集中在3—9月,季节分布上主要集中在春季和夏季,降雨时间极不均匀,具有明显随季节变化特征; 近10年苏州市降雨总量明显增加,且多雨月份也有所增加,相比较之前2个时段,月平均降水量增加约20 mm。
Abstract:
According to the rainfall data of three rainfall stations(Changshu, Fengqiao and Pingwang)within Suzhou territory from 1988 to 2017, the characteristics of rainfall inter-annual variation were analyzed, and the monthly and seasonal distribution of rainfall of Suzhou city was analyzed from three time periods of 1990s, 2000s and 2010s. The results showed that during the study period, the rainfall in Suzhou showed a significant upward trend, with the largest in the middle, followed by the south and the smallest in the north. The rainfall decreased from the middle to the north and south sides of Suzhou. The monthly distribution of rainfall was mainly concentrated in March to September, and the seasonal distribution was mainly concentrated in spring and summer. The rainfall time was extremely uneven with obvious seasonal variation characteristics. In recent ten years, the total rainfall in Suzhou had increased significantly, and the rainy months had also increased. Compared with the previous two periods, the average monthly rainfall increased by about 20mm.
