But a new study shows that they typically have a very down-to-earth core, consisting of dust and metallic particles. Cirrus clouds are important to global climate … WebEach year, several billion tonnes of mineral dust are lofted into the atmosphere from the world’s arid regions, making dust one of the most abundant types of aerosol particles in the atmosphere. Now, scientists are learning that tiny bits of dust from the hottest and driest parts of the Earth are a surprisingly large driver in forming the delicate, wispy ice clouds …
