What does cloud cover measure?

In meteorology, cloud cover is measured in oktas, or eighths of the sky. If you look up at the sky, and mentally divide it into eight boxes, then imagine all the cloud you can see squashed into these boxes. How many boxes does the cloud fill? This is how many oktas of cloud there are.

How do I know if I have cloud cover?

Cloud cover is measured on an eight point scale, 0 Oktas being clear sky , one Octa being 1/8 of the sky covered in cloud, and so on up to 8 Oktas – completely overcast. Measure off the sides of the mirror so that each side will be split into four equal parts.

What is cloud cover in simple terms?

Cloud cover (also known as cloudiness, cloudage, or cloud amount) refers to the fraction of the sky obscured by clouds when observed from a particular location. The cloud cover is correlated to the sunshine duration as the least cloudy locales are the sunniest ones while the cloudiest areas are the least sunny places.

What does high cloud cover mean?

Clouds Reflect Radiation When the sun’s energy enters the atmosphere, some of it is reflected off of clouds. This means that high cloud cover can contribute to a cooling effect: more radiation reflected means less heat present in the atmosphere.

What is an example of cloud cover?

For example, thick, gray, stratus clouds that bring heavy precipitation are called nimbostratus. Meanwhile, lower level clouds often reflect heat from the sun back into space and keep the surface temperatures cool. Cloud cover can also limit the cooling that occurs in a region at night.

What causes cloud coverage?

Clouds warm and dry Earth’s atmosphere and supply water to the surface by forming precipitation. Clouds are themselves created by the motions of the atmosphere that are caused by the warming or cooling of radiation and precipitation.

What’s the best way to measure cloud cover?

For the novice meteorologist, NASA suggests a few low-tech methods of observing cloud cover, including a spherical sky mirror and a measuring system developed for the naked eye.
