Title: Strange admospheric phenomenon?
Post by: jeffball on September 14, 2004, 09:03:46 am
[font color=\'#000000\']Hello Eduard,
I am not an expert, but I believe these are converging crepescular rays.  The convergence is a matter of perspective much like railroad tracks converge as the approach our horizon perspective.  Here is a quick link I found that I believe describes the phenomena you have imaged.  Hope this helps and is accurate.

[font color=\'#000000\']Hi all,
This is my first topic here and since you know a lot about landscapes and nature, can any of you explain the following phenomenon:

This was taken from my balcony in the evening facing East, so the sun was behind me (the Netherlands), about 30 minutes before setting. It dipped below the clouds making the sunrays come out very nicely. However, they converge instead of diverge. I was very amazed to see this.Has anyone experienced this before? An explanation perhaps?

Thanks...
