中文摘要 |
利用区域气候和大气化学模式系统,对2000年春季生物质燃烧排放影响东南亚及中国南部地区对流层臭氧含量进行模拟研究.结果表明,春季东南亚和南亚的生物质燃烧不仅影响源区对流层臭氧含量,而且对处于环流下游的中国南部地区也有显著作用;燃烧源区主要影响对流层低层,下游地区则影响对流层中低层.在源区引起的对流层臭氧总浓度增加达2.1×10-1g/m2,对下游的中国南部地区增加量为9.0~12.0×10-2g/m2;源区大气低层1000~900hPa的臭氧含量可增加36×10-9m3/m3 以上,而在中国南部750~700hPa高度上空的增加达15×10-9m3/m3.

英文摘要 |
The ozone variation led by biomass burning in Spring 2000 over South East Asia and South of China region was simulated with a combined regional climate model and atmospheric chemical model. It was found that ozone was added by the pollutant of biomass burning both over source area and down wind area. The ozone of lower troposphere was affected by the pollutant over source area, so did the ozone in middle troposphere over down wind area. An ozone increase of 9.0~12.0×10-2 g/m2 over South of China was found. The range of ozone increase between 1000~900hPa over source area was more than 36×10-9m3/m3. |
