Blood Rain

Everyone assumes that rain will just be water dropping from the sky. There is never a need to be concerned because the science is quite simple. Except for those very few times when the water isn't as it should be. Yellow, brown, and even black rain have all been seen to fall in the past. However, no other colored rain that people have ever witnessed is quite as unsettling as red rain. Why? because it is "blood rain," which is a really ominous name.

Writing about rain that falls like blood has a long history. It was described by Homer as a penalty meted out by Zeus himself. But it also happens in the present day and in actual life, but without an older god's wrath. The reality, which is almost entirely due to dust, is much less spectacular than the name suggests. In areas like the Sahara, wind may travel enormous distances through the atmosphere and whip up small dust particles. It can eventually shower down again in hues that are fairly brilliant and stunning, sometimes dark enough to stain garments, depending on the type of dust it picked up.
