We study the seasonal distribution of condensate clouds and dust clouds during roughly 1 Martian year using these daily global maps. We present the development and decay of the tropical cloud belt and the polar hoods, the spatial and temporal distributions of lee waves and spiral clouds, and an unusual “aster” cloud above the volcanoes, consisting of rays around a central disk, like the flower. The tropical cloud belt contains mostly fibrous clouds during northern spring/early summer and convective clouds during middle/late northern summer. The detailed development and decay of the tropical cloud belt is nonuniform in longitude. Two distinct stormy periods in late summer precede the formation of the north and south circumpolar hoods. The north polar storms in late summer resemble baroclinic frontal systems on Earth but contain both dust and condensate clouds. Spiral clouds occur only in the northern high latitudes and only during northern spring and summer. The north polar hood displays a stationary wave number two structure during the fall and winter. The south polar hood has fewer streak clouds and lee wave clouds than the north polar hood. During this particular year the lee wave cloud abundance in the south had two peaks (in early fall and late winter), and the lee wave cloud abundance in the north had one peak (in early fall).</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383388845210774144","@type":"Researcher","foaf:name":[{"@value":"Huiqun Wang"}],"jpcoar:affiliationName":[{"@value":"Division of Geological and Planetary Sciences California Institute of Technology  Pasadena California USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1380298342686578176","@type":"Researcher","foaf:name":[{"@value":"Andrew P.
