Based on aerosol–cloud interaction, the Arctic region is composed of three distinct ‘regimes’, as demonstrated in a study published in the Nature Geoscience journal.

Clouds in the Arctic are among the biggest unanswered questions in climate science, with particular uncertainty about how the minute particles found in the air known as aerosols drive cloud formation and how clouds affect the number of aerosols as the region warms.
One key question is the significance of aerosols originating in atmospheric trace gases. As they grow, these particles can turn into cloud condensation nuclei, meaning particles on whose surface water vapour condenses into droplets.
