摘要
根据江苏省近50年来的梅雨资料,用数学统计方法对入、出梅的迟早作了定义,考虑到梅期的长短、梅雨量及暴雨日数等3个因子,给出了梅雨强度计算模型及梅期旱涝指标,并分析了江苏省淮河以南地区近50年来梅期旱涝分布特征,最后阐述了入梅迟早对旱涝灾害的影响。
Based on the data of plum rain in recent 50 years in Jiangsu province, the time when plum rains start and end is defined by mathematic means. Considering plum rain duration and rainfall and days of rainstorm, a model for calculating the intensity of plum rains and indexes in assessing drought and waterlogging are given. Distribution characteristics of drought and waterlogging in the course of plum rains are analyzed. Finally, effects of the starting time of plum rains on drought and waterlogging are expatiated.
