The HKO e-Bulletin on Educational Resources is published on-line every three months. It covers in layman terms various interesting topics related to weather phenomena and popular science, as well as developments in new science and technology related to the Observatory's service on meteorology, radiation and geophysics. We welcome your views and suggestions.

This issue takes "Rainstorms" as the theme. A number of articles are written to explain this phenomenon. Moreover, there is one interesting article on a mysterious atmospheric optical phenomenon - "glory". In order to help readers understanding the mystery, the author tries to illustrate the phenomenon more in depth with diagrams. Since the serious nuclear accident of the Fukushima nuclear power plant of Japan in March this year, people are very concerned about nuclear-related matters. There are two articles related to "Radiation". Other articles on different, interesting and meaningful topics are also included.
