Why is it that when it’s a really cold night outside, the sky is so much clearer & crisper to see the stars more clearly? [Serious]
The sky isn't clear because it's cold, it's cold because the sky is clear. Clouds act like a blanket that keep the warmth radiating from the earth's surface escaping into the upper atmosphere so easily. Without the clouds, the heat escapes.
The Short Answer
The sky isn't clear because it's cold, it's cold because the sky is clear. Clouds act like a blanket that keep the warmth radiating from the earth's surface escaping into the upper atmosphere so easily. Without the clouds, the heat escapes. This is why deserts are usually freezing cold at night – no moisture for clouds.
