What Causes the Sky to Turn Wild Colors During Wildfires?
Wildfires are a common occurrence in many parts of the world, and while they offer a beautiful yet eerie sight, they cause immense destruction and loss of life. The smoke from wildfires often makes the sky turn wild colors, ranging from orange to red and even purple. This phenomenon occurs due to several reasons, which are explained below.
1. Rayleigh Scattering
Rayleigh scattering is a phenomenon that occurs when smoke particles in the air scatter sunlight. When the smoke particles are small, they scatter the shorter wavelengths of light, such as blue and green. This leaves the longer wavelengths, such as yellow, orange, and red, to travel through the atmosphere. As a result, the sky appears to be shades of orange and red.
2. Absorption of Light
The smoke produced by wildfires also contains a significant amount of soot and other pollutants. These particles absorb the light of particular wavelengths, causing the sky to appear to be in various shades of purple. The absorption of light rays can cause the sky to turn an unusual color that is not visible under normal conditions.
3. Reflection of Light
The smoke from wildfires reflects sunlight, causing the sky to take on various colors. When the sun is low on the horizon, its rays have to travel a longer path through the atmosphere. This causes them to scatter more, creating a more noticeable effect when reflecting off the smoke particles.
Importance of Precautions During Wildfires
While the sight of a smoke-filled sky can be captivating, it is important to note that wildfires cause significant harm to both humans and the environment. The smoke produced by wildfires can cause respiratory problems and other health issues, making it imperative to take precautions and avoid exposure whenever possible.
List of Precautions
- Stay indoors
- Avoid physical activity outdoors
- Keep windows and doors closed to prevent smoke from entering the house
- Use air purifiers with HEPA filters to improve indoor air quality
- If driving, recirculate the air in the car and keep windows closed
- Wear a face mask when outdoors
