What kind of weather is the sunset carmine when there is no rain and wind?

When the sun goes down, it is crimson. This shows that the atmosphere contains more water vapor and impurities, so blue light is completely scattered by the atmosphere, leaving only red light with the longest wavelength, so the color of the sun we see is carmine. Because the atmosphere already contains more impurities such as water vapor and dust, it is generally easier to cause rainfall. However, it should be pointed out that there are only a lot of water vapor and dust in the atmosphere (mainly playing the role of condensation nuclei), and there are no other conditions (such as system influence, mountain effect, thermal convection, etc.), which is not enough to form precipitation. Therefore, "sunset red" can only say that it is more likely to rain in the future, and it needs to refer to whether other conditions are met. If it happens, it may be said that the weather will turn to rain, otherwise it is impossible to have the phenomenon of "no rain and no wind".
