Cloud cover (also known as cloudiness, cloudage, or cloud amount) refers to the fraction of the sky obscured by clouds on average when observed from a particular location. Okta is the usual unit for measurement of the cloud cover. 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, as c… WebRecording observations for over 100 years.

WebCloud cover or cloud amount is total part of the sky covered by clouds expressed as a percentage, although it was a special symbol on paper weather map before. Cloud … WebIn 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. 0 oktas represents the complete absence of cloud. WebThe unit of measure for cloud cover is the Okta. 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. How do you read an aviation Metar? crystal open date
