What is sunrise, no rain is wind or something?

Sunrise is red in the southeast, and there will be wind when there is no rain. ?

sunset is carmine, and no rain is wind.

this is a meteorological proverb. Literally: the sunset and the western hills are all red, either rain or wind.

when the sun goes down, it is crimson. This shows that the atmosphere contains more water vapor and impurities, so the blue light is completely scattered by the atmosphere, leaving only the red light with the longest wavelength, so the color of the sun we see is carmine.

Because the atmosphere already contains many impurities such as water vapor and dust, it is generally more likely to cause rain. However, it should be pointed out that there is only a lot of water vapor and dust in the atmosphere (mainly acting as condensation nuclei), and it is not enough to form precipitation without the influence of other conditions (such as system influence, mountain effect, thermal convection, etc.). Therefore, "sunset carmine" can only say that it is more likely to be rainy in the future, and it is also necessary to refer to whether other conditions have been met. If it is met, it is possible to say that the weather will turn rainy, otherwise it is impossible to have the phenomenon of "no rain is wind".
