这枚戒指的云是什么?

我们在乐高乐园最近在温莎(SE英格兰),到一天结束的时候,我们注意到什么看起来像一个环的云在天空中。这是相当大的(很难说是天空中我们没有测量它的参考点)。它轻轻地改变了形状,因为它上涨,可能由于风,直到消失。

谁能解释这是什么吗?谢谢

#这可能是一个烟雾戒指,但不是以确定。有几个在过去的几年里看到类似的对象。——一个环被* *(在/ Spa) (http://www.huffingtonpost.co.uk/2014/04/15/black-ring-of-leamington-spa-_n_5150871.html)在2014年* *。关于它的起源的理论包括一群昆虫,以及一个普通的烟囱(也许是环住在一块的无度地长时间)。最终,他们发现(它是一个烟花测试的结果)(http://www.bbc.com/news/blogs -杂志-监控- 27037579)。[![在这里输入图像描述][1]][1]——一个相似的对象被* *[哈萨克斯坦](http://www.huffingtonpost.co.uk/2015/04/07/black-ring-kazakhstan_n_7015928.html)在2015年* *。视频收到了相当多的宣传,许多人贴上一个不明飞行物。在这个例子中,对象是~直径100米,~在海拔200到1000米。烟囱假说被再次提出。 [Another article](http://www.dailymail.co.uk/news/article-3027519/Holy-smoke-Mysterious-100m-wide-black-ring-filmed-floating-clear-skies-Kazakhstan.html) mentions that some people attributed the ring to [thermal microbursts](https://en.wikipedia.org/wiki/Microburst) (see also [here](https://ll.mit.edu/publications/journal/pdf/vol01_no1/1.1.4.microbursts.pdf)); however, microbursts move down, and your ring rose up. [![enter image description here][2]][2] - An irregular ring was observed **[in Birkenshaw](https://www.thesun.co.uk/news/4008168/mystery-black-rings-in-sky-around-world-pictures/) earlier this year (2017)**. This case is notable because the ring in this case was distinctly non-planar; it was warped, just like yours. It may have been [from an explosion from a military reenactment](http://www.mirror.co.uk/news/uk-news/explained-mysterious-black-smoke-ring-10795042). [![enter image description here][3]][3] This article notes that another ring was seen in Windsor, right near where you were: [![enter image description here][4]][4] There are many more examples besides these. Some notable features about these rings: - They are "hazy" or smeared in parts. In your case, you can see a dark section on the left; the Leamington Spa ring has a smear on the upper left and the Kazakhstan ring has a smear on the right. - The rings are pretty circular. This may be an indication that they are artificial. - Most are flat, but some (like yours) exhibit some warping, which could indeed be cause by wind. - The rings are darker than the clouds around them, as we can see in all cases but that Kazakhstan ring. - They were sighted near places where explosions were taking place on the ground ([a similar ring in California](http://www.express.co.uk/news/weird/679422/ALIEN-PORTAL-Sinister-black-ring-UFO-terrifies-families-at-Disneyland) was seen at Disneyland). I'm willing to rule out microbursts in your case because the ring rose. Insects are still a possibility, and perhaps the smears are due to individual bugs flying outside the pattern, but I have yet to see any behavioral study to explain it. This leaves the theory that these rings are from smokestacks or certain detonations, which is well-supported. Not all of the rings were seen near heavy industrial areas, mind you, but that doesn't rule out that hypothesis in those cases. Smaller smoke machines or explosions could still be the culprits, possibly at a ride in Legoland itself. The most similar type of cloud I can think of is a [lenticular cloud](https://en.wikipedia.org/wiki/Lenticular_cloud), a common explanation for UFO sightings: [![enter image description here][5]][5] <br> <sup>[Image](https://commons.wikimedia.org/wiki/File:Lenticular_Cloud_over_Harold%27s_Cross_Dublin_Ireland_30-6-15.jpg) courtesy of Wikipedia user Omnisource5 under [the Creative Commons Attribution-Share Alike 4.0 International license](https://creativecommons.org/licenses/by-sa/4.0/deed.en).</sup> However, lenticular clouds aren't ring-shaped, but disk-shaped, and they usually aren't quite that flat. Therefore, I'd rule a lenticular cloud out here.
