Since a “clear” sky can include some clouds (as long as it’s less than 1/2 okta), it is possible to report cloud type even when you report a clear sky! The unit of cloud amount – okta – is an eighth of the sky dome covered by cloud. Today, cloud cover is measured using automated weather stations, specifically the ceilometer and the sky imager instruments. That warmed air starts to rise because, when warm, it is lighter and less dense than the air around it.

Note how increasing cloud cover is shown by covering more and more eighths (oktas) of the circle. In meteorology, an okta is a unit of measurement used to describe the amount of cloud cover at any given location such as a weather station. Dew Point 77°. Density [0-1] is the intensity of the particles making up each cloud. Less bars means that the forecast is likely to change in the next model run. Cloud Cover = 4.0 Oktas Cloud Height = 643.1 m Precipitation Rate = 0.0 mm/h Solar Radiation = 53.6 W/m 2 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. Total Cloud Cover Low Cloud Classifications Middle Cloud Classifications High Cloud Classifications. In other words, 4 oktas equals 5 tenths. A clear sky is 0 oktas, while a totally overcast or gray sky is 8 oktas. 12 Comments. Fig 1. The term cloud amount in reference to a genus, a species, a variety, a layer, or a certain combination of clouds indicates the fraction of the sky cover by that genus, species, variety, layer or combination.. Okta is the usual unit of measurement of the cloud cover. The cloud amount is defined as 'the proportion of the celestial dome which is covered by cloud. Cover [0-1] is the fraction of cloud cover over the space occupied by clouds. Pressure & Precip. The unit of cloud amount – okta – is an eighth of the sky dome covered by cloud. Sky needs to be mentally divide it into eight boxes, then all the visible clouds are squashed into these boxes. The number of filled boxes is how many oktas of cloud there are. Cloud amounts are generally round up to the next okta.
