After a storm, it is not uncommon to see a yellow or even orange tint in the sky. This phenomenon can be perplexing and often leads to questions about what causes it. In this article, we will explore the possible reasons why the sky may appear yellow after a storm.

Atmospheric Scattering

One of the most common reasons for the yellow or orange hue in the sky after a storm is atmospheric scattering. This occurs when the sun is low on the horizon, and the light has to travel through a greater distance of the Earth’s atmosphere. During this journey, the shorter wavelengths of blue light are scattered more than the longer wavelengths of red, yellow, and orange light. As a result, these colors become more prominent, creating a yellow or orange tint in the sky.

Pollution

Pollution can also be a factor in the yellow sky phenomenon after a storm. Air pollution, such as that caused by car exhaust and industrial emissions, can create a layer of smog that traps the sunlight and produces a yellow or orange hue in the sky.

Dust and Sandstorms

Dust and sandstorms can also contribute to a yellow or orange sky after a storm. When a storm picks up dust or sand, it can suspend these particles in the air. These particles scatter sunlight, creating a yellow or orange tint in the sky. The larger and denser the particles, the more pronounced the effect.

Wildfire Smoke

Wildfire smoke can also cause the sky to appear yellow after a storm. When there is a nearby wildfire, smoke particles can be carried by the wind, creating a hazy atmosphere. This smoke can scatter the sunlight and cause the sky to appear yellow or orange.

Conclusion

In conclusion, the yellow or orange tint in the sky after a storm can be caused by atmospheric scattering, pollution, dust and sandstorms, and wildfire smoke. While this phenomenon may seem strange or alarming, it is a natural occurrence caused by various factors. By understanding the science behind it, we can appreciate the beauty and complexity of our planet’s atmosphere.
