Cloud cover refers to the fraction of the sky covered by clouds at a given time. It is usually expressed in oktas, which is a scale from 0 to 8, where 0 means clear skies and 8 indicates complete cloud cover. Cloud cover plays a significant role in weather patterns, influencing temperature, precipitation, and sunlight. Meteorologists use cloud cover data to predict weather conditions and understand climate changes. Different types of clouds, such as cumulus, stratus, and cirrus, contribute to varying levels of cloud cover. This information is essential for activities like agriculture, aviation, and outdoor planning.
