I know its good, but what causes red sky at night?

Question

sailors delight means good weather tomorrow

Answer 1

At certain times, when large numbers of particles are present, the scattering of the light is so strong that the Sun is left with only orange/red colours, the other colours having being scattered. And sometimes even red light is scattered, turning the sky a whole range of red-orange colours.


Dust particles act as nucleation centres for the formation of raindrops. This leads to the familiar 'red sky at morning shepherd's warning'. However, if a red sky occurs at night the night-time rain will have cleared the dust from the atmosphere to produce a sparklingly clear bright day. Hence, 'red sky at night, shepherd's/sailor's delight'

Answer 2

"Red sky at night, sailors delight. Red sky in morning, sailors
take warning."

When your grandparents repeated this familiar refrain, they were
using weather lore, which is based on observation of the environment and the effect that changes in weather have upon insects, animals, birds and people.

Moisture and clouds in the atmosphere cause the red sky seen by the sailor. The red sky in morning shows that the rising sun is
reflecting from clouds that are streaming eastward. These clouds will soon generate rainstorms since they are just arriving overhead.

Answer 3

I've heard that a red haze is caused by air pollution so perhaps it's not a good thing. I feel like I notice it most on warm nights, which are very rare in my town, but that could be skewed by me going out more often on warm nights than any other.

Answer 4

It can be true in a way, but here in Hungary, with its Great Plain they say it means wind is coming next day - they didn't know in the old times, but it's becuse of the dust in the air. Here is an answer I found online for your question.

Answer 5

water droplets in the clouds scatter light.

at dusk, most of the sunlight coming into the earth's atmosphere are of the longer wavelengths, i.e., red-orange . these are then scattered by the water droplets in the clouds that are present.

so if the night sky is cloudy, it appears reddish.

Answer 6

This is because the water on the sky is too much

Answer 7

A hot day or random.

Answer 8

global warming

Answer 9

It was dust and polluted and maybe clouds...
