blood rain
Red-tinted falling water
Blood rain is rain tinged red or brown, typically from dust or sand carried aloft from distant deserts and mixed with precipitation.
The phenomenon has occurred throughout recorded history, often interpreted as an omen or divine sign before its atmospheric explanation was understood.
Reports of blood rain in southern Europe usually trace to Saharan dust.
