利用装备高时空分辨率仪器的飞机对2006年春季沙尘暴期间中国北方沿海地区超细颗粒物的垂直分布进行了观测。观测到沙尘暴、弱沙尘暴和非沙尘暴三种不同类型的条件。结果表明，弱沙尘暴期间，超细颗粒物的数量浓度可达1.2×105cm−3。结果表明，在直径10nm左右出现了成核新粒子的峰值。在沙尘暴期间，超细颗粒浓度低于无沙尘暴时，且数量浓度呈多峰分布，有待进一步研究。观测结果可为认识华北地区大气污染的过程和机制提供有价值的信息，并为模式计算提供基本参数。
The vertical distribution of ultrafine particles over Northern China coastal areas was measured by aircraft equipped with a high space–time resolution instrument during dust storms in spring of 2006. Three different types of conditions were observed, i.e. dust storm, weak dust storm and non-dust storm. Results indicate that the number concentration of ultrafine particles can reach up to 1.2×105cm−3during weak dust storm. It is found that the peak of newly formed particle by nucleation appeared around 10nm diameter. During the dust storms, the concentration of ultrafine particles was lower than those when no dust storms occurred, and the number concentration showed multiple-peak distribution, which needs further research. Our observational results may provide valuable information for recognizing the process and mechanism of air pollution in the Northern China area, and basic parameters for model calculation.
