What will the rainbow weather be like in the east?

One thing can be confirmed first, it is not a rainbow, because the direction of the rainbow is opposite to that of the sun. If the sun is in the east, the rainbow will be in the west.

That's actually a solar halo, because the humidity in the air is relatively high, and water will form many tiny ice crystals in a low temperature environment, and these ice crystals will refract and scatter sunlight, so the color of the solar halo you see is caused by this scattering.
