秋季华南低温冷害气候特征

利用１９５１－１９９０年９－１０月广东、广西、福建和海南４８个气象台站资料，讨论华南秋季低温冷害气气候特点。分析发现，低温冷害过程频数自北往南递减，从沿海向内陆逐渐增加，年总日数自北往南迅速减少，南北差别大；出现的时间和降温强度随高度分别提早和增强，持续时间从北往南迅速缩短，极端最低气温从北南升高，沿海高于内陆，强低温冷害所有９年，主要集中在６０年代后期到８０年低初。

The Climatic Characters of Chilling Damage in South China during Autumn

The climatic charaters of chilling damage in autumn in South China are analysed with the observations at 48 stations, September to October, 1951-1990. The results show that the mean frequency of chilling damage decreases from north to south and increases from coast to inland in South China. Continuous time of the chilling damage process shortens rapidly from north to south in the area. The number of strong chilling damage year was 9 year (1951-1990). However, less of them occurred from 1951 to 1965 and most of them happened during 1966-1980.
