【摘要】:利用廣東省86個氣象觀測站1961—2013年記錄霾日資料和1981—2013年統(tǒng)計霾日資料,采用線性趨勢分析、計算氣候趨勢系數(shù)等統(tǒng)計診斷方法,分析了廣東記錄霾日和統(tǒng)計霾日的氣候特征并進行比較。結(jié)果表明:廣東統(tǒng)計霾日與記錄霾日的年平均分布非常相似,但是統(tǒng)計霾日數(shù)比記錄霾日數(shù)明顯增加10~80 d。廣東霾分布可劃分為三個區(qū):(1)多霾區(qū):包括珠江三角洲、北部的南雄、東南部的汕頭,年統(tǒng)計霾日40.0~144.5d;(2)一般霾區(qū):包括廣東中部偏北的部分地區(qū),年統(tǒng)計霾日20.0~39.9 d;(3)少霾區(qū):廣東西南部和東部大部分地區(qū),年統(tǒng)計霾日1.0~19.9 d。廣東年記錄霾日和統(tǒng)計霾日均以11 d(10 a)的速率明顯上升,1990年后顯著增加,特別是2003年以來上升非常明顯,2007年達到最大,但2008年以來逐年波動下降。廣東年霾日數(shù)增加最明顯的區(qū)域在珠三角、汕頭、南雄等地。1980—2013年的廣東平均年記錄霾日序列與統(tǒng)計霾日序列的相關(guān)系數(shù)達0.78,顯著相關(guān)。分析表明統(tǒng)計霾日比記錄霾日總體上更客觀合理,并對兩者存在差異的原因進行了分析與討論。
[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.
