Antwort Why do clouds turn black before rain? Weitere Antworten – Why is it raining so much in Europe
Above-average ocean temperatures – partly due to the El Nino weather pattern – are causing evaporation and therefore more rain in low-lying regions. And sea level rise is causing rivers to burst their banks more frequently.When it's about to rain, clouds darken because the water vapor is clumping together into raindrops, leaving larger spaces between drops of water. Less light is reflected. The rain cloud appears black or gray. Clouds form when air becomes saturated, or filled, with water vapor.
- Cumulonimbus clouds are dense, vertical, towering clouds commonly associated with instability in the atmosphere and thunderstorms.
- produce lightning, thunder, heavy rain, hail, strong winds and tornadoes.
- The tallest among all clouds, cumulonimbus clouds span all cloud layers and extend above 2 km.
Why are nimbus clouds dark : Nimbus clouds are known as the dark rain clouds. They contain a very high concentration of water droplets. The concentration is so high that they do not allow sunlight to pass through them.

What’s the rainiest city in Europe : Bergen, Norway
Bergen, Norway
Topping the data table for being both the city with the highest average rain days per month (12.7) as well as the highest average daily rainfall (8.8mm), Bergen is the outright rainiest city in Europe.
No, not necessarily. It just means you're looking up at the shadow side of a cloud that's thick (large) enough to absorb and scatter most of the sunlight falling on to it. As a result it appears dark relative to other parts of the sky.
It has to do with drop size and rising currents of air. If the air does not generate updrafts that allows for the build up of larger droplets of water that result in sprinkles, they don't form. You could think of this overcast being a fog that is not on the ground.
What are the 4 types of clouds
The four main types of clouds are cumulus, cirrus, stratus, and nimbus.colorless
Clouds themselves are actually colorless, because water and ice are colorless. But there is a catch. The water droplets can absorb and reflect light. This is why they appear white when light is reflected from them.Just east of Hamburg, you can find the small city of Oldenburg, judged to be Germany's wettest city.
Almeria, Spain
Look no further than Almeria, Spain: Europe's driest city, and indeed one of the least rainy places in the world. At roughly 1,000 years old, the city is a relative youngster in general terms of the Mediterranean, but you can still find your fair share of history here to explore – and let's not forget the weather!
What part of Germany gets the most rain : While Oldenburg in Lower Saxony has the highest annual precipitation (1.072 mm) in the whole country, the second, third, fourth and fifth rainiest cities in Germany are all in North-Rhine Westphalia.
What causes clouds to turn black : Clouds are made up of countless microscopic water droplets. Those droplets scatter incoming light from the sun so that only a small fraction of it reaches our eyes. The thicker the cloud, the darker it appears.
Do dark clouds mean thunder
However, not all dark clouds will result in precipitation or thunderstorms. If the lower part of the atmosphere is unstable (relative warm air below colder air), air will rise until it becomes saturated and cumulus clouds are forming.
As clouds thicken, sunlight passing through them will diminish or be blocked, giving the cloud a gray color. If there is no direct sunlight striking the cloud, it may even reflect the color of the sky and appear bluish.High-Level Clouds
- Cirrus (Ci) Detached clouds in the form of white, delicate filaments, mostly in patches or narrow bands.
- Cirrocumulus (Cc)
- Cirrostratus (Cs)
- Altocumulus (Ac)
- Altostratus (As)
- Nimbostratus (Ns)
- Cumulus (Cu)
- Cumulonimbus (Cb)
Why do clouds turn black : Each water droplet scatters some of the sunlight passing through it. The more water droplets in the path of a ray of sunlight the more light is scattered, the less gets through and the darker the cloud becomes.
