摘要
按照冯佩芝等的中国南方秋季低温冷害（俗称“寒露风”）评估办法［１］，对１９６１～１９９３年长江中下游至华南地区３４个站９～１０月逐日温度资料进行了微机处理和分析，填补了１９８０年以后的低温冷害有关资料及其评定结果，并完善和修正了文献［１］中１９６１～１９８０年间个别年份的评定结果；通过对１９５１～１９９３年４３年的资料分析表明，中国南方秋季低温冷害明显具有发生率高、为害范围大、影响时间长、表现形式复杂、群发性和成灾严重等主要特征。
Based on Feng’s method for assessment of chilling damage in autumn (the common saying is Wind at Cold Dews) in south China, data of day to day temperature collected from 34 stations in Hua Nan reaches and Middle Lower reaches of Yangtzi river during September and October in 1961-1993, were calculated and analysed. The results showed that the chilling damage in autumn had some notable characteristics, such as the high rate of occurrence, long period of influence, large areas of damage, complicated expression, and serious consequences, etc. The result of the chilling damage is related to the general atmosphere circulation and temperature changes in autumn in China.
