二氧化硫浓度的垂直分布对云下雨水酸化的影响
- EFFECT OF VERTICAL DISTRIBUTION OF ATMOSPHERIC SULPHUR DIOXIDE ON THE ACIDIFICATION OF RAIN WATER BELOW THE CLOUDS
- 摘要：用一物理化学模式讨论了云下雨水的酸化过程.参照重庆地区的实际情况,讨论了SO2随高度指数分布和其它分布对酸化的影响及近地面层高浓度SO2对酸化的影响.SO2平均浓度与实际垂直分布相比较,地面雨水成份相差较小,用平均浓度代替实际垂直分布是可行的.
- Abstract：The acidification of rain water below the clouds in Chongqing area was investigated and a physical-chemical model was suggested to describe the vertical distribution of sulphur dioxide and its effect on the acidification process. The results indicated that the acidified rain water from upper atmosphere would not be remarkably modified in low atmosphere with high concentiation of sulphur dioxide, while the rain water not affected through upper atmosphere would be acidified in boundary layer. The vertical distribution of rain water component was not much differ from the average component.
- Key words：acid rain sulphur dioxide.
