What is the sign that the sky turns yellow?

First, there should be clouds when it rains, and then there should be water in the clouds. Clouds form water, and water cannot remove media such as dust. The sky is blue and orange because dust refracts light differently, so it has color. Similarly, due to the interference of a large number of water and dust media, sunlight cannot be refracted, and the light reaching the earth's surface is also reduced.

What is the sign that the sky turns yellow?

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

2. The sky turns yellow, which 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 they are not enough for human eyes. When precipitation forms, after neutralizing these dust spirits, the color of the falling rain will be influenced by the local soil, which is 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: possible "acid rain" and atmospheric hazards caused by other natural disasters.
