我国极端降水事件的变化特征分析
Journal: Ecological Environment and Protection DOI: 10.12238/eep.v5i4.1606
Abstract
本论文使用1951–2016年中国839个测站的逐日降水资料,采用95百分位的极端降水定义方法,分析了我国极端降水事件发生频率和强度的时空变化特征,并进一步对五个典型地区(东北、新疆、华南、长江流域、黄淮流域)进行了月变化和年变化的探讨。得到的主要结论如下：极端降水事件多发生于35°N以南的长江中下游地区和华南地区,其强度也相对较大；而西北地区极端降水发生的频率和强度均很小。季节上,极端降水主要发生在夏季,频率极大值在东北、新疆和黄淮流域出现在7月,长江流域为6月,而华南则在6月和8月有双极大值的分布特征。极端降水强度在同一地区的季节差异较小,但区域差异较大。此外,极端降水事件发生频率和强度大体呈现增大并增强的趋势。
