摘要
长春市大气SO_2浓度具有采暖期明显高于非采暖期的特点,大气SO_2浓度与风速、通风系数呈负相关,与气压呈正相关;与云量的关系依时间变化而不同.大气SO_2的垂直变化在2000m以下梯度较大,在2000m以上梯度变化趋缓.
The Annual change of atomspheric sulphur dioxide content, which is much higher from middle November to early March than from April to October, and the daily change which is the highest in daybreak and nightfall, are very obvious in Changchun City. There is a close relationship between them. Through correlation analysis, it can be found that atomspheric sulphur dioxide content is negatively correlated with wind speed, ventilation quantity, and cloud amount in the evening, and positively correlated with atmospheric pressure and cloud amount in the morning.
