Why cumulonimbus clouds are dangerous?
A cumulonimbus cloud (CB) is dangerous because of the processes occurring in them. Threats within the cloud are severe turbulence, very strong updrafts (some as high as 100 m/s or more) and downdrafts containing torrential rain, hail and lightning.
What do black clouds mean?
A: Very dark looking or black clouds are probably those that contain a lot of rain in them and part of a thunderstorm, McRoberts adds. “In general, the severity of a storm is related to cloud height, which is why dark clouds are usually an indicator of bad weather.
Do clouds cool the Earth?
Clouds cool Earth’s surface by reflecting incoming sunlight. Clouds warm Earth’s surface by absorbing heat emitted from the surface and re-radiating it back down toward the surface. Clouds warm or cool Earth’s atmosphere by absorbing heat emitted from the surface and radiating it to space.

Are clouds important?
Clouds are essential to the earth-atmosphere system. Clouds help regulate Earth’s energy balance by reflecting and scattering solar radiation and by absorbing Earth’s infrared energy. Clouds are required for precipitation to occur and, hence are an essential part of the hydrologic cycle.
Can pilots see at night?
The short answer is no. If you’ve ever gazed out your window into the inky blackness during a nighttime flight, you’ve probably wondered how the pilots are able to see anything from the cockpit. The blinking LED light visible from the ground actually serves a beacon to help other pilots spot the plane in the air.
Are clouds dirty?
Scientists have known for years that cloud formation is an extremely dirty business that depends on microscopic particles (aerosols) from the surface of the Earth. These particles allow water vapor to condense, and without them cloud droplets, mist, or fog could not form at all.
Why are clouds pink?
Red, orange and pink clouds occur almost entirely at sunrise and sunset and are the result of the scattering of sunlight by the atmosphere. The clouds do not become that color; they are reflecting long and unscattered rays of sunlight, which are predominant at those hours.
Why do clouds become black?
When clouds are thin, they let a large portion of the light through and appear white. But like any objects that transmit light, the thicker they are, the less light makes it through. As their thickness increases, the bottoms of clouds look darker but still scatter all colors. We perceive this as gray.
Is the sun White?
The color of the sun is white. The sun emits all colors of the rainbow more or less evenly and in physics, we call this combination “white”. That is why we can see so many different colors in the natural world under the illumination of sunlight.

Pilots will actively avoid taking the aircraft into Cumulonimbus type clouds as they can be hazardous to aviation. They can be very turbulent due to the updrafts and downdrafts, contain icing, heavy rain and hail and lightning.
What are thunder clouds called?
Why do clouds move?
Clouds move because the wind is carrying the parcel of cloudy air along. The droplets in the cloud are moving fast with the wind, but new cloud drops are always forming in the same place where the air is pushed up near the hill, so the front of the cloud appears stationary. …
Why do planes avoid clouds?
The low visibility encountered when flying through clouds means using Instrument Flight Rules are necessary. This explains the need, not only legally but also practically to avoid clouds during flight if you are not IFR rated.
Do pilots avoid thunderstorms?
Answer: Pilots use onboard weather radar to remain clear of thunderstorms during day and night operations. Lightning is actually easier to see at night, which shows the pilots the location of the storm.
