There are several questions that have been asked frequently about our recent paper in Nature Geoscience. Here are answers to some of them. What are stratocumulus clouds? Stratocumulus are low-lying clouds with tops typically below 2 km (7000 ft) altitude. They are the most frequent cloud type on Earth and, over oceans, often form nearly unbroken decks covering thousands of square kilometers. In the subtropics, they are especially prevalent over eastern ocean basins, for example, off the coasts of California, Peru/Chile, and Namibia/Angola. Why are they important for Earth’s climate? Stratocumulus clouds cover about 20% of the tropical ocean area (between 30°S … Continue reading FAQ: Possible climate transitions from breakup of stratocumulus decks under greenhouse warming
