They are thin and wispy in appearance, often appearing as delicate, high-altitude filaments or strands. Their wispy shape comes from wind currents, which twist and spread the ice crystals into strands. They are usually white or have a light gray color. In the daytime, they are whiter than any other cloud in the sky. They are commonly known as &#8220;mare&#8217;s tails&#8221; because they are shaped like the tail of a horse.<\/p>\n<p><strong>Source: <\/strong><a href=\"https:\/\/indianexpress.com\/article\/explained\/explained-sci-tech\/pyrocumulonimbus-cloud-when-wildfires-spit-storms-lightning-9501605\/\" target=\"_blank\" rel=\"nofollow noopener\">How Pyrocumulonimbus clouds are formed when wildfires spit storms, lightning<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pyrocumulonimbus Clouds are thunder clouds created by intense heat from the Earth\u2019s surface.<\/p>\n","protected":false},"author":5,"featured_media":25677,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-25676","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/25676","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=25676"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/25676\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/25677"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=25676"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=25676"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=25676"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
