A sheet of cirrostratus which is very extensive, nearly always ends by covering the whole sky. A milky veil of fog (or thin stratus) is distinguished from a veil of cirrostratus of a similar appearance by the halo phenomena which the sun or the moon nearly always produces in a layer of cirrostratus. ]]></termNote><termCreatedDate>2026-03-30 20:37:35</termCreatedDate><relation><relationType>UF</relationType><termId>31361674</termId><termName>cirrostratus cloud</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31361675</termId><termName>clouds, cirrostratus</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31327381</termId><termName>clouds</termName><termType>PT</termType></relation></term>  </Zthes>
