Partly Cloudy is a 2009 American animated comedy short film, written and directed by Peter Sohn [2] and produced by Kevin Reher. [3] It was shown in theaters before Pixar's feature film Up and is a special feature on its DVD and Blu-ray release. It was included in the Animation Show of Shows in 2009.
Overcast or overcast weather, as defined by the World Meteorological Organization, is the meteorological condition of clouds obscuring at least 95% of the sky. [1] However, the total cloud cover must not be entirely due to obscuring phenomena near the surface, such as fog .
The average cloud cover of the Earth, 2005-2013. Colors range from blue (no clouds) to white (totally cloudy). [6] (click for more detail) Cloud cover values only vary by 3% from year-to-year averages, whereas the local, day-to-day variability in cloud amounts typically rises to 30% over the globe.

The scattering of direct sunlight on those clouds results in the same polarization pattern. In other words, the proportion of the sky that follows the Rayleigh Sky Model is high for both clear skies and cloudy skies. The pattern is also clearly visible in small visible patches of sky. The celestial angle of polarization is unaffected by clouds.
An inversion is also produced whenever radiation from the surface of the earth exceeds the amount of radiation received from the sun, which commonly occurs at night, or during the winter when the sun is very low in the sky. This effect is virtually confined to land regions as the ocean retains heat far longer.

Daylight is the combination of all direct and indirect sunlight during the daytime.This includes direct sunlight, diffuse sky radiation, and (often) both of these reflected by Earth and terrestrial objects, like landforms and buildings.
