'Euphoric rays' is not a meteorological term, Trevor, and it is difficult to
see why they are termed so as a title for the photo in the June edition of
Weather, unless the picture is meant to induce a feeling of euphoria in the
observer. However, crepuscular rays are formed by particulate matter in
suspension in the atmosphere, which may be composed of dust, salt particles,
pollution products, water or ice meteors. The rays become visible when the
illuminated particles are crossed by shadows cast by clouds, or more rarely,
mountains.
I took some photos of crepuscular rays almost two years ago. There was a
lot of Saharan dust in the air then and it was those particles which caused
the affect

There's another pic of crepuscular rays on my website. If you right
click and save it's a bit bigger than displayed.
