Classification of Inorganic Small Spherical Particles in Rime and Snow at the Summit of Mt. Kajigamori, Shikoku Island, Japan

In order to investigate the long-range transfer mechanism of inorganic small spherical particles in wet-depositions, such as rime, snow and glaze, on the summit of Mt. Kajigamori (1399.4 m alt.), Kochi, Shikoku Island, in 2011-2013, the residue was obtained with a 0.45 mu m pore-sized filter and then, a single-particle analysis was carried out for ones below 3 gm by using a Low-Vacuum Tabletop scanning electron microscope-energy dispersion X-ray spectroscopy (SEM-EDX). Particles were classified in the six categories according to their compositions. In this work, it was found that two majour types of distribution patterns of the particles were presented. It was proposed that these depended on the 24 hrs back-trajectory, such as a typical fly-ash category in Huabei type and a Fe-Si-Al particle category in Dongbei type in China. The Zn-included particles were also analyzed.
