摘要

摘要研究了特征尺寸为 10-7-10-6 m 的粒子在地球大气层和外层空间边界的温度动态。以石墨为例，研究表明，在距离地球表面 80-90 千米的高空，粒径为 5×10-7 米或更小的微粒会被加热到超过开始发光的温度（约 900 K），温度达到 2000 K 以上，并发出淡淡的绿松石光。根据所获得的结果，可以得出这样的结论：从地球表面观测到的假黎明和日落后的银色云团是一簇白热纳米粒子。

Nature of Silvery Clouds

Abstract

The dynamics of the temperature of particles with a characteristic size of 10^–7–10^–6 m at the boundary of Earth’s atmosphere and outer space is considered. Using graphite as an example, it is shown that at an altitude of 80–90 km from Earth’s surface, particles with a size of ∼5 × 10^–7 m or less can be heated above the temperature of the beginning of the glow (~900 K), reaching temperatures of more than 2000 K with a light turquoise glow. Based on the results obtained, it is concluded that the silvery clouds observed in the false dawn and after sunset from Earth’s surface are a cluster of white-hot nanoparticles.
