Last evening my youngest son was on his way to the grocery store when he spotted these amazing clouds and came right over to get me outside to see them. So glad he did.
I wondered what causes clouds to be red, orange or even peach-coloured. Here's what I read:
Just before sunrise or just after sunset , light rays from the sun follow a longer path through the denser part of the atmosphere near the bend in the earth's surface near the horizon. Most of the blue light is filtered out and only the longer wave lengths are left... first yellow then red. That's why as the earth rolls away from the sun, presenting a thicker atmosphere for light to penetrate, the colour of the clouds changes from yellow to roange to red.
You probably already knew all this but I found it very interesting.
The above pics were taken to the East while the one below was in the Western sky.
