摘要:

利用O3数据、气溶胶指数和风场观测资料,对发生在中国黑龙江大兴安岭和印度尼西亚地区的特大火灾进行了分析。结果表明:(1)在火灾发生后,研究区及下风方区域O3总量均有增加;(2)此次黑龙江火灾释放出的CO、NOX、CH4等大气成分是造成5月O3总量增加的主要原因;(3)进一步分析黑龙江火灾发生时期的环流形势发现,火灾发生前,3、4月O3总量的增加来源于西风气流对中高纬高浓度O3的平流输送,而5月则与火灾有较为密切的关系;(4)新加坡和菲律宾地区O3含量增加似乎也与O3前体物有关。

关键词: 森林火灾指数气溶胶指数O3平流效应    
Abstract:

Based on the forest fires data, total O3 amount, aerosol index and flow field data, the effect of the biggest fire process happened in Heilongjiang Province in China and Indonesia on the atmospheric ozone was analyzed. The results show that: (1) The total ozone amount in the studying region and the leeward side area had increased in the period of fire disaster; (2) The extremely serious forest fire happened in Heilongjiang had released a large amount of atmospheric species gases, such as CO, NOX and CH4, which have some contribution to the O3 increase; (3) Further analysis the circulation feature revealed that, the increased ozone in March and April can be due to the ozone advective transportation by westerly wind, which can transfer the air containing high concentration ozone in high latitude to the studying region. While in May, the forest fire process played an important role in the O3 enhancement; (4) The increase of total ozone in Singapore and Philippines also seems to be related to the ozone precursor released from the forest fire.

Key words: Forest-fire index    Aerosol index    O3    Advection effect
