Extremely sunny or cloudy days are more common now than in the 1980s, and swings between thunder storms and sunny days are more common.

Researchers developed a computer system to examine weather data on a daily level, rather than analysing monthly averages as many existing climate change models do.

Greater fluctuation in extreme weather patterns might change how the atmosphere distributes heat and rainfall. Ecosystems, pest and disease control are impacted, as well as industries vulnerable to changes in weather such as agriculture and solar energy.
