| 摘 要： | 详细分析了１９９６、１９９７年春末夏初在辽宁省进行的大气气深胶飞机观测的０～５ｋｍ气深胶粒子数深度和尺度谱分布的垂直、水平变化，初步讨论了它们与温度和相对温度的关系。结果表明，混合层顶上下粒子数深度具有不同的垂直分布特征；粒子谱受不同形成机制影响，表现为多峰分布；水平方向上气溶胶粒子数浓度存在显著变化；温度层结和相对温度对气溶胶粒子的浓度和谱分布有明显影响。

| Abstract: | Airborne measurements of atmospheric aerosols were made during 16 aircraft flights in 10 days conducted over Liaoning province,China in the early summer of 1996 and 1997.This paper deals with aerosol concentration and size distribution under 5 km and their spatial changes.Correlations of aerosol concentration with temperature and relative humidity are analyzed.Results demonstrate that there are different vertical distributions of aerosol concentrations between the mixed layer and free atmosphere.Due to different formative processes,aerosol distribution is of multi modal.Aerosol concentrations have considerable changes along horizontal flight legs.Inversion layer and relative humidity have significant influences on aerosol concentration and size distribution. |
