A new study has revealed that dry weather patterns are becoming increasingly common across the globe. While this may have implications for crop production, water security and hydropower generation, the study also found that dry weather can also lead to an increase in air quality.

The study, conducted by researchers at the University of California, Irvine, examined data from 672 weather stations located in 83 countries over the last 60 years. The researchers found that the number of dry days—defined as days with precipitation amounts lower than 0.1 millimeters—had increased in most regions.

The findings suggest that dry weather patterns are becoming an increasingly common phenomenon, and could have a serious impact on food security, water supplies, and hydropower generation. Additionally, the study also shows that dry weather can lead to an increase in air quality. This is because, in the absence of precipitation, air pollutants can remain in the atmosphere for longer, allowing them to accumulate and lead to higher levels of air pollution.
