But because generation occurs only when sunlight is strong, supply to the grid fluctuates broadly with daylight and cloud cover, and all but the most modern and expensive grid connections have trouble accommodating the irregularity of supply.
As a few hours of daylight backlighted the cloud cover, Hirzinger-Merchant led Harding and Azarias out for a 35-mile bike ride.
In September, the ozone hole is at its largest because the cold winter months coupled with the returning daylight permit stratospheric cloud formations that do the most damage to the ozone layer.
Use HDR for interior shots in daylight, landscapes with dramatic clouds, or city shots at night, for instance.
Regular chroma-keying replaces a single key color with an overlaid image, but the grass or turf on a football field contains a range of colors, from shadowy dark greens to mud brown, and the colors can change as daylight fades or as clouds pass in front of the sun.
Moving clouds by daylight and lightning flashes by night told them how much warm air was rising.
Daylighting climate data including cloud cover, cloud form, sunlight condition, solar elevation, atmospheric mass, direct illuminance, diffuse illuminance, and globe illuminance were obtained in a study from 14 cities through two consecutive years of observation of natural light (1983 to 1984) in typical Chinese light-climate regions [1].
The gamma ray measurement experiments required darkness, but the B-17 drones that would sample the clouds needed daylight to control them.
The weather becomes thick in the north, the clouds cover the sky, daylight becomes sparse, thunder and lightning ring out, and it begins to rain.
Winters are clear-skied and bone-dry, the air seductively warm during the daylight hours, but because there is no cloud cover, cold at night and in the early mornings.
