More Information
Summary:In-situ aircraft measurements of CCN(Cloud Condensation Nuclei) of 4 flights under the foggy and hazy weather during the period from September to October are analyzed in Shijiazhuang, China. The Analysis of the vertical distribution, the horizontal distribution and the size distribution of CCN were conducted in this article. According to the expression N=CSk, the CCN spectra can be derived. The fitted spectra parameters C(2853) and k(about 0.61) in Shijiazhuang area show the characters of continental CCN. The clouds had an obvious consumption effect on CCN particles, and the inversion layer can make the number concentration of CCN increase in this area.
