【摘要】 利用历史天气图、地面气候和历史灾情资料,对广东历史上7次严重冬季寒害的天气形势、气候特征及其影响进行分析。结果表明,尽管寒害发生的天气、气候特征不一,但多数是由中弱冷空气多次补充造成的,并未达到寒潮标准。在全球气候变暖的大趋势下,20世纪90年代寒害出现的次数却明显增多,寒害影响范围大,它给农业造成的损失,不亚于一般的台风暴雨灾害。更多还原

【Abstract】 According to synoptic chart, ground climate and disaster loss data in history, synoptic situation, climatic characters of seven serious chilly disasters in Guangdong province and their influence on agriculture were analyzed. The results showed that although synoptic situation and climatic characters of chilly disasters were different, most of them were caused by moderate or weak cool air which didn’t meet criterion of cold air time after time. The trend of global climate was warming, however, occurring times of chilly disasters obviously increased in 1990’s. Because of its larger range, chilly disaster’s influence on agriculture is not less than that of typhoon and rainstorm.更多还原
