In winter, westward-moving spiral-shaped storm systems, similar to those on Earth, are seen regularly at midlatitudes. Thin clouds are common at the morning terminator (the dividing line between the lit and unlit portions of the planet’s disk), and orographic clouds, produced when moist air is lifted over elevated terrain and cooled, form around prominent topographic features such as craters and volcanoes. Low-lying clouds and fogs are often observed within topographic depressions-i.e., valleys or craters. Despite the small amount of water present, the atmosphere is near saturation, and water-ice clouds are common. If it all precipitated out, it would form a layer of ice crystals only 10 micrometres (0.0004 inch) thick, which could be gathered into a solid block of ice not much larger than a medium-sized terrestrial iceberg. Only small amounts of water are present in the atmosphere today. Surface pressures range over a factor of 15 because of the large altitude variations in Mars’s topography. The atmosphere is very thin, exerting less than 1 percent of Earth’s atmospheric pressure at the surface. Kuiper ascertained from telescopic observations in 1947 that the Martian atmosphere is composed mainly of carbon dioxide.
