对目前有关前汛期开始和结束日期的研究工作进行了总结.提出应参照梅雨期和季风降水等有关日期划分问题的方法,使用比月平均资料更高精度的逐日(候)资料,选择能够表征华南前汛期降水特征的适宜区域和代表站点,综合考虑降水、环流及其它物理要素在前汛期开始和结束前、后的演变特征,从而客观、准确地划定各年前汛期的起始和结束日期,以用于华南前汛期问题的研究.

A Review on Recent Researches on the First Rainy Season's Onset and End Dates in South China

To make an objective and significant definition, suggestions on the usage of the data, the selection of the appropriate region and the representative stations in South China, the period of the rainy season, the threshold of each parameter quantity, such as precipitation, wind field and so on, and their synthesis are reasonably discussed under the reference measures in defining Meiyu and the summer monsoon precipitation which are all related with the judgment on date definition.
