Clear sky Sky with a total cloud cover of less than one okta (or one-tenth in the United States).
clear sky"A sky free of clouds and other obscurations as observed from the point of observation.
Clear Sky - When the sky has no clouds.
Climate - It describes the average weather conditions in a certain place or during a certain season. Weather may change from day to day, but climate changes only over hundreds or thousands of years.
This is more pronounced when you have a clear sky.Radiational InversionUsed interchangably with Nocturnal Inversion; a temperature inversion that develops during the night as a result of radiational cooling of the surface.
0 indicates a clear sky and 1.0 (or 10/10) indicates a completely covered sky. The following classifications are used in aviation weather observations: clear, scattered, broken, overcast, partial obscuration, obscuration.
Clear Sky Condition: When the sky is cloudless or is less than .1 cover.
Climate: The type of weather over and area or region based on many years of average weather information. Temperature, rainfall, snowfall, etc.
Favorable conditions for radiation fog are clear sky, little or no wind, and high relative humidity. It occurs in stable air and is primarily a night time or early morning phenomenon.
Radiation fog is formed by the cooling of land after sunset by thermal (infrared) radiation in calm conditions with clear sky. The cool ground then produces condensation in the nearby air by heat conduction.
The 24/7 Nowcast: Clear sky. Comfortable temperatures too, mainly 50s falling into the 40s.
This is more pronounced when you have a clear sky.

unlimited ceiling—A clear sky or a sky cover that does not meet the criteria for a ceiling.
unstable—Set instability.
updraft—A localized upward current of air.
Radiation Fog: Fog formed over land at nights characterized by light winds, clear sky and moist air in the low levels of the atmosphere.
The downward motion inhibits further convection and the growth of additional thermals from below, which is why fair weather cumulus typically have expanses of clear sky between them.
Okta: meaning eighth, is the form used to report coverage of the sky in cloud. Eight Oktas is full coverage with Zero Oktas being a clear sky.
Orographic waves: a wavelike airflow produced over and in the lee of a mountain barrier.
The cooling of the Earth's surface. At night, the Earth suffers a net heat loss to space due to terrestrial cooling. This is more pronounced when you have a clear sky.
Radiational Inversion ...
Diamond Dust: Ice crystals glittered like diamonds in sun, moon or artificial light. Individual crystals appear to float in the air. Term often used to describe fall of ice crystals from apparently clear sky.
In this case the day could be termed 'sunny' even though more than half the sky may be covered in cirrus cloud.
Cloudy: Predominantly more cloud than clear sky for example, ...
The eye remains calm with light winds and often a clear sky. Hurricanes may move as fast as 50 mph, and can become incredibly destructive when they hit land.
0 indicates a clear sky and 1.0 (or 10/10) indicates a completely covered sky. Amount of sky cover for any given level is determined according to the summation principle.
