【摘要】：利用广东省86个气象观测站1961—2013年记录霾日资料和1981—2013年统计霾日资料,采用线性趋势分析、计算气候趋势系数等统计诊断方法,分析了广东记录霾日和统计霾日的气候特征并进行比较。结果表明:广东统计霾日与记录霾日的年平均分布非常相似,但是统计霾日数比记录霾日数明显增加10~80 d。广东霾分布可划分为三个区:(1)多霾区:包括珠江三角洲、北部的南雄、东南部的汕头,年统计霾日40.0~144.5d;(2)一般霾区:包括广东中部偏北的部分地区,年统计霾日20.0~39.9 d;(3)少霾区:广东西南部和东部大部分地区,年统计霾日1.0~19.9 d。广东年记录霾日和统计霾日均以11 d(10 a)的速率明显上升,1990年后显著增加,特别是2003年以来上升非常明显,2007年达到最大,但2008年以来逐年波动下降。广东年霾日数增加最明显的区域在珠三角、汕头、南雄等地。1980—2013年的广东平均年记录霾日序列与统计霾日序列的相关系数达0.78,显著相关。分析表明统计霾日比记录霾日总体上更客观合理,并对两者存在差异的原因进行了分析与讨论。
[Abstract]:The use of 86 meteorological observatories in Guangdong province from 1961 to 2013 and 1981 to record the haze haze in 2013 statistical data, using linear trend analysis, calculation of climate trend coefficient statistical diagnostic methods, analysis of the climatic characteristics of Guangdong records and statistical haze haze days were compared. The results showed that: Guangdong haze and statistical records the distribution of annual average haze days are very similar, but the statistical number of haze days than the record number of haze days increased 10~80 D. Guangdong haze distribution can be divided into three areas: (1) haze area: including the Pearl River Delta, northern Nanxiong, southeastern Shantou, annual haze days 40.0~144.5d; (2) general haze area: including parts of North Central Guangdong, annual haze days 20.0~39.9 D; (3) less haze area: most areas of southwestern and Eastern Guangdong, annual haze days 1.0~19.9 Guangdong D. records and statistical haze haze days at 11 d (10 A) rate significantly L, increased significantly after 1990, especially since 2003 increased significantly, reached the highest in 2007, but since 2008 has lower volatility. Guangdong haze days increased obviously in the area of Pearl River Delta, Shantou, Nanxiong and other places.1980 in Guangdong in 2013 the average annual record of haze sequence and statistical haze sequence correlation coefficient 0.78. Statistical analysis showed that significant correlation of haze days than recorded haze days are generally more objective and reasonable, and the reason for the difference is analyzed and discussed.
