Researchers Unveil Effects of Dust Particles on Cloud Properties


-Scientists use powerful techniques to visualize effects of dust particles on cloud formations-

Overview of the press release

An international team led by Japanese scientists has generated significant findings that highlight the impact of high-latitude dusts on the conversion of clouds’ water droplets to ice—or glaciation—within low-level clouds in the Arctic region. These results contribute to a better understanding of factors at the land surface and how they affect cloud formations. The research findings also add to a better understanding of how climate is affected by clouds, which are increasingly considered to be among the most important—yet complex—regulators of the global climate. Depending on the conditions, clouds either enhance warming or help cool the climate by trapping heat or reflecting sunlight back into space, respectively.

The study was published in Nature Geoscience on March 25, 2019.
