摘 要: 以2008年广东低温雨雪冰冻灾害天气及其影响为研究切入点,本文根据史料和气象资料分析了110年来广东地区出现的10次低温雨雪天气及灾害情况,认为太阳黑子活动与冰灾的产生有一定的相关关系.研究发现广东冰灾多出现在太阳活动谷年及其附近;冰灾与太阳黑子活动11年和22年的周期有相关性;太阳黑子活动谷年前后,则广东冰灾发生的机率会更高. Based on the historical and meteorological data,this paper makes an analysis of the ten severe strikes by freezing rain and snow weather at Guangdong in the past 110 years and their disasters.It argues that the strikes have much to do with the Solar activity in Guangdong.The sunspot activity period is markedly correlated with the occurrence of these disasters.It has also been found that the ice disaster occurs in the minimum year of sunspot activity or thereabouts and it has very good relevance to the sun-spot cycles of 11a and 22a.Close to the time after the minimum year of sunspot activity,the occurrence probability of ice disaster is higher.
