The main reason why rain clouds are dark is due to their particulate density. As clouds are formed from minuscule water droplets and/or ice crystals, the denser they are packed, the more light radiating from the Sun is scattered and dispersed by them, lending a darker appearance to their lower sections.
Why does it get dark before it rains?
Thicker clouds look darker than thinner ones, which let more light through and so appear white. Richard Brill, a professor at Honolulu Community College, gives this answer: It is the thickness, or height of clouds, that makes them look gray. … When light contains all colors, we perceive it as white.
Why do dark clouds bring rain?
But why are rain clouds so dark? … That is, a cloud gets thicker and denser as it gathers more water droplets and ice crystals — the thicker it gets, the more light it scatters, resulting in less light penetrating all the way through it.
Can it rain without clouds at night?
Because rain forms when droplets of condensed moisture grow large enough to descend quickly into the air, their absence can make it impossible for rain to occur. That means if there are no clouds overhead, rain cannot happen as well.
Does it always rain in Winden?
Winden experiences some seasonal variation in monthly rainfall. Rain falls throughout the year in Winden. The month with the most rain in Winden is May, with an average rainfall of 2.1 inches. The month with the least rain in Winden is February, with an average rainfall of 1.3 inches.
Why does the sky turn gray?
A: On hazy days, large particles in the air make the sky appear gray or even white, McRoberts explains. “These larger particles tend to scatter more wavelengths of light in the color spectrum,” he says. … This phenomenon is called Mie scattering. To sum it up, the way light is scattered determines the color of the sky.”
How do clouds turn GREY?
When clouds are thin all the light is able to penetrate through but when clouds are high and thick some of the light is not able to go all the way through. As the clouds get thicker, the flat bottoms of the cloud can still scatter all light but because of the height and thickness, we see it as gray.
Do GREY clouds means rain?
Most clouds are white, but rain clouds are usually a darker shade of gray. … The thicker a cloud gets, the less light can pass through it. So when you look up at a rain cloud, the base or bottom of it looks gray. But not all dark clouds bring rain, and sometimes this is hard to predict.
Do altostratus clouds rain?
Altostratus clouds are “strato” type clouds (see below) that possess a flat and uniform type texture in the mid levels. … However, altostratus clouds themselves do not produce significant precipitation at the surface, although sprinkles or occasionally light showers may occur from a thick alto- stratus deck.
How does water vapor turn into rain?
Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice. … When they get too heavy to stay suspended in the cloud, even with updrafts within the cloud, they fall to Earth as rain.
Can a cloud burst?
Cloudbursts are infrequent as they occur only via the ‘orographic lift’ or occasionally when a warm air parcel mixes with cooler air, resulting in sudden condensation. The term ‘cloudburst’ was coined from the notion that clouds were akin to water balloons and could burst, resulting in rapid precipitation.
Can it rain fish?
Yes. Although rare, there are numerous instances of fish falling down from the skies. Of course, the fish do not really “rain” in the sense of condensing out of water vapor. … All sorts of creatures have been reported raining down, including snakes, worms, and crabs, but fish and frogs are the most common.
Can it rain frogs?
Frog rain is a rare meteorological phenomenon in which frogs get swept up in a storm, travel miles and then fall from the sky when the clouds release the water. It doesn’t happen frequently, but it does happen in parts of the world.
