峨眉宝光研究之二——对宝光伴生大光环的研究

Study on Emei’s Glory.Part Ⅱ: Research of Great Optic Ring Emerging with Glory

根据四个宝光实例的分析 ,指出峨眉宝光的伴生大光环并不都是主虹。由冰晶云雾产生的宝光 ,其伴生的大光环实为对日 (月 )晕 ,从而肯定了近年来盛行的范氏(Van de Hulst)宝光形成的后向散射机理 ,不能用以解释一切宝光现象 ,否定了冰晶云雾不能产生宝光的局限认识。还指出了《国际气象词典》中“布格晕”条释义的错误。

It is indicated according to the analysis of four cases that a great optic ring accompanied by glory is not always a primary rainbow.The great ring emerging with glory caused by ice cloud and fog is in fact an anti-solar(moon)halo,which is leading to a conclusion that the dominant Van de Hulst's backward scattering theory on the formation of glory in recent years can not be used to illustrate all phenomenon concerning glory and gives a denial to the formulation that ice cloud and fog cannot produce any glories.It is also pointed out that there is an error in the explanations of Bouguer's halo in the International Meteorological Vocabulary.
