We found that more birds were killed following nights with [greater than or equal to] 50% cloud cover
and northerly winds, with our two largest kills occurring under these conditions at WILL.
The following night, Dec 15/16, Gordon MacLeod observing from Bower, by Wick in the far north of Scotland, managed to glimpse three Geminids and a bright sporadic between 21:00UT and 22:00 UT in fair conditions with some cloud cover
Early estimates of cloud cover
were based on surface observations of cloud distribution; this is subjective and lacks spatial information on cloud extent (Spinhirne et al.
Royal Commission on Environmental Protection found that the net effects of ozone, contrail, and aviation-induced cloud cover
is likely to triple the warming effect of aircraft-emitted C[O.
Svensmark's results, which have been published in the Proceedings of the Royal Society, remain controversial but may revolutionize climate science--a field that has lacked a thorough understanding of the effects of cloud cover
An improved laser ceilometer-which can measure up to four layers of cloud cover
from zero to 30,000 feet-has been unveiled by All Weather Inc.
Such forecasts not only account for atmospheric ozone, which filters UV radiation, but also a region's altitude and cloud cover
Computer algorithms convert these signatures into measures of forest cover, soil moisture, cloud cover
, ocean chlorophyll content, and many other useful parameters.
This is most evident in Den Hartog's manipulation of color and opacity: Where the water is stormy, its surface seems to take on the reflected gray of cloud cover
, and where the artist suggests turbulent shallows, her materials become appropriately frothy.
Real-time weather information including wind speed, cloud cover
and stages of the moon for night missions is available at their fingertips.
Low and slow-moving cloud cover
prevented them from seeing anything there.
The wide variability was due to time of day, cloud cover
and surface water movements when the measurements were taken.
