What is the sign that the sky turns yellow?

1, the yellowing of the sky is generally a precursor to heavy rain, which is normal for natural phenomena such as wind, rain and lightning, and will not be a precursor to earthquakes.

2. The yellowing of the sky is the effect of mirror and spherical reflection such as refraction, reflection and scattering of rain.

3. Rainwater turns yellow, which may be influenced by local air quality. As we all know, clouds are not as clean as they seem. They are composed of dust and water droplets. There are still a lot of dust and water droplets in the air under the clouds, but it is not enough for human eyes. When precipitation is formed, after neutralizing these dust spirits, the color of the falling rain will be affected by the local soil, showing yellow, red and black.

4. The sky and rain turn yellow, which may be a rare natural phenomenon of sandstorm accompanied by rainfall.

5. Another: natural disasters such as "acid rain" that may be caused by atmospheric hazards.
