Why Is The Sky Blue During The Day But Red During Sunrise And Sunset?

In space, one of the most impressive representations of the beauty of nature is the colors of the sky, which captivate the eyes with their eternally changing colors and has amazed humanity for years. Among the most common questions surrounding this phenomenon is: However, many questions about the properties of the sky remain. Why does the sky appear blue during the day but red during sunrise and sunset? To enlighten yourself on this issue, you need to immerse in the ins and outs of light, atmosphere, and celestial geometry, no doubt.

There are factors influencing sky colors beyond temperature, with moisture, size, and angle of particles impacting their appearance.

Blue Sky During Daytime

The scattering of light by molecules and small particles including dust in the atmosphere is the primary reason of the blue color of the sky during the day. The blue color the sky gets is due to the Rayleigh scattering process. This process implies that short blue wavelengths illuminate the air in every direction throughout the fill air filled with gases and particles.

Reddish Crepuscular Skyrise and Sunset

These two components are the exact opposite of a sunrise and sunset, and the sky that is opened as a visual treat with a wide range of red, blue, and pink colors. However, such an effect is the outcome of a special mechanism taking place: Rayleigh scattering followed by Mie scattering. Anyway, when brighter portion of the day is over the sunlight must travel through a thicker atmosphere, which happens near the horizon. Subsequently, the short bluish and greenish wavelengths of the scattered light are left behind while the long reddish and orange-hued wavelengths are predominant in the sky.

Atmospheric Temperature and Fog Clearness

Oxygen Quality and Particle Materials

The brightness and purity of the air is the driving force that helps us observe the vibrant and glowing hues of blue, yellow, purple, or orange skies. The beauty of dawns and sunsets in the places with the smaller scale of pollution level and no air contaminants is usually incomparable to that of dusks and sunsets in the other areas. In contrast, it has been found that in the areas with more pollutants, the colors of the natural phenomena would be understated or faded by the scattering and the absorption of light by particles such as dust, soot, and others.

Cloud cover plays an important role in the global heat balance. Thus, the changes in the cloud cover also contribute to local weather patterns.

It is the presence of clouds as well which often accounts for the variation in the sky view as that of at sunrise and at sunset. Usually behind a crystal clear blue sky, faint sunrays can be glimpsed, benefitting solar flares and intensifying earth-trapping colors during dawn and dusk. As well, clouds can enhance the visual spectacle by reflecting and refracting sunlight that redirects some of the light to the ground, offering additional insight on the intensity of the scene.

Geographical and Astronomical Factors

Latitude and Seasonal Variations

Location of the globe is a vital point, which influences time of dawn and dusk phenomena. Longitudinal differences change the angle of the sunlight in the atmosphere, thus impacting the time the twilight lasts and the level of vividness at which color gradients are displayed. Besides that, the angles of the Earth’s rotational axis that surely induce variations in the direction of sunlight also result in astonishing sunlight tracks belonging to different times of year.

Atmospheric Optics and Celestial Geometry which gives us the pleasure to observe the different bodies that are situated in the space.

Apart from the general science of atmospheric optics which explains how light interacts with atmospheric conditions, there are more specific developments having applications in operational forecasters. Examples of scattering and bending of rays, such as the atmospheric refraction, dispersion, and the Tyndall effect cause the direct or indirect path-travel of light rays . These effects also lead to the observed change in coloration of the sky during different times of the day.

Cultural and Mythological Significance

Furthermore, the different hues of rainbow denote not only the scientific one, but also cultural and mythological aspects of the different parts of the planet. The symbolism tied with sunrise and sunset crosses several human cultures that were existed before up to the modern world. Common ideas come with this symbolism such as the renewal, transition and the circular setting of lives.

This marvelous phenomenon of color change of the sky gives everyone an opportunity to witness such harmony of light, air and celestial components. Although the daytime brings tranquil and azure colors, the reflection of the setting sun that emerges at the dawn of a new day and at the dusk provides us with the opportunity to experience the simply beauty of our natural world. Our views are broadened and enriched as the hidden scientific facts of colorful heavenly lights and occurrences which govern them are tried to discover.
