When you step outside on a cold winter night, with lights shining on the snow Have you noticed that the sky has taken on an unusually bright hue?

Perhaps when you saw this view you stopped and looked up at the sky again, You might wonder why. We’re here to explain why!

During the winter months, especially when it snows, nights can be clearer.

This is related to the characteristics of the weather and snow. Cold air is denser. People are generally more thinking the moist air would be ‘thick’ contradict each other, but that is not the case.

Hot and humid weather, warm and is less dense than dry air because water vapor is lighter than other gases in the air. Heavier, thicker air can hold small ice crystals aloft, especially on very cold days.

Different colors such as crystals, moonlight, street lights and even front door lights reflects light sources It is quite effective. The colder and denser the air, the more light is scattered in a given area.

What about the snow effect?

thick on the ground Snow cover is great at reflecting light. Snow has albedo, which is the ability to reflect or attract light. The albedo of snow is very high, meaning it reflects a lot of light energy.

So whatever the light source, snowy winter nights are among the brightest nights of the year. These reflective properties of snow and sky the sky changes color can cause.

When light is reflected by dense, cold air and snow layers, certain wavelengths of light becomes clearer. Light from artificial sources, especially city lights, can take on a bright color due to these reflections.
