Újabb email jött Marko Riikonentõl.

Beleásta magát a szakirodalomba, és most arra hajlik, hogy igenis hívjuk ezt a jelenséget is Bishop-gyûrûnek. A finnek ugyan hivatalosan nem így teszik, de Minnaert és a csehek igen. Itt a kivágott email részlet. Na, többet nem fárasztalak benneteket ilyen hosszú levelekkel, de gondoltam érdekel a dolog titeket is.

"I dont know if the name is reserved for the stratospheric volcanic corona. The original Bishops observation is of volcanic corona. In Finland observers have called only volcanic coronas as Bishops rings. I just re-checked what Minnaert says. He calls also a forest fire corona as Bishops ring, so for him any large
corona apparently was Bishops ring. It would be interesting to know what has been said about Bishops ring between the original observation and Minnaert. Czech observers call any large coronas as Bishops ring. So from this point of view your Bishops ring definition for the Saharan dust corona is all right. What ever we call them, as long as we all understand each other, its all right."
