What weather pattern does the moon turn red tomorrow represent? Why?

In fact, if you see the moon near the ground when it is red, it doesn't mean anything. The dust density near the ground is high, which absorbs more light except red light, and finally leaves only red light, so the moon looks red. In addition, the red moon appears on a foggy day for similar reasons.

As for astronomy, there is another rare phenomenon that can lead to the red moon, and that is the total lunar eclipse. When the moon completely enters the shadow of the earth, there will be a phenomenon of red moon. This is because only the red light with the longest wavelength can enter the shadow of the earth. Of course, this phenomenon can only appear on the fifteenth day of the lunar calendar, not every month.
