摘要:
基于2018年12月10日在华中地区的一次飞机观测,利用DMT机载资料分析了华中地区的气溶胶与云微物理量的分布特征。结果表明,气溶胶数浓度随着高度的增加而迅速降低,低层气溶胶有效直径主要集中在0.4μm。在高层,上升段的气溶胶有效直径随着高度缓慢增加,集中在2~2.5μm范围内;下降段的气溶胶有效直径在垂直方向上复杂多变,离散度也大,主要集中在0.5~1μm。气溶胶粒子谱为多峰分布,第一峰值直径在0.14μm。气溶胶粒子主要集中在小粒径端,随着粒子尺度的增大,气溶胶浓度逐渐降低,粒径在0.3~0.4μm之间的气溶胶浓度减小最快。在不同高度上的云滴谱均呈现多峰分布,第一峰值直径在6μm,云滴谱宽约50μm。
Abstract:
Based on an aircraft observation in Central China on December 10, 2018, this paper analyzes the distribution characteristics of aerosol and cloud microphysical quantities in Central China by using DMT airborne data. The results show that the aerosol number concentration decreases rapidly with the increase of altitude, and the effective diameter of low-level aerosol is mainly concentrated at 0.4μm. In the upper layer, the aerosol effective diameter in the ascending section increases slowly with the height, and is concentrated in 2~2.5μm; The aerosol effective diameter in the descending section is complex and changeable in the vertical direction, and the dispersion is also large, mainly concentrated in 0.5~1μm. The aerosol particle spectrum is multi-modal, and the diameter of the first peak is 0.14μm. Aerosol particles are mainly concentrated at the small particle size. With the increase of particle size, the aerosol concentration gradually decreases, and between 0.3~0.4μm decreases the fastest. The cloud drop spectra at different heights show a multi peak distribution, and the diameter of the first peak is 6μm. The spectral width of cloud drops is about 50μm.
