Rainbow formation
-
Geography and weather books would say when there is drizzle (rain) when there is shine almost concurrently, you get a rainbow in the opposite side (direction) where sun appears. http://en.wikipedia.org/wiki/Rainbow[^] But there was very interesting scenario in Chennai with sharp drizzles amidst bright sunshine. But all along about 20 miles drive I was having, I could not spot the rainbow forming at all. I was driving on the highway and hence a good visibility was there. In some view, it would be like 'Rainbow-Chasing', quite similar to Storm-Chasing? :-D

well, it is a little more complicated than that, but that is basically the Physics behind it. It also matters the humidity of the air and the light scatter before and after the rainbow forms and a few other things, especially wind which could shift the angle of the droplets and thus the angle of refraction away from the viewer. :-D

Midday there's essentially no rainbox, sunset you can get the full half circle.

It was actually in the morning itself, not even a full forenoon. There wasn't much sunshine though. It just resembled a pleasant-rainy day.

That's not quite complete. The rain has to be on the side of your shadow. Rain between you and the sun will not form a rainbow (visible from your location).

This is also dependent on lattitude. The primary rainbow is ~42* away from your shadow, so if the sun is more than 42* degrees above the horizon the primary will be entirely below the horizon. The secondary is ~50* but is about 10x dimmer and much less visible as a result.
