* *为什么积云只有基本的云类型喜欢闪电吗?* *因为上升的速度在上升气流是闪电形成的基础,如本例所示的情节从[总闪电活动的一项指标上升气流特征Deierling和彼得森][1]:[![updraftvslightning][2]][2]空气上升越快,使更多的闪电。只有快速上升气流可以单独的费用足够快来克服耗散和建立[数亿伏][3][ESE问题][4])(相关所需的闪电。三个标准的云分类,只有积云涉及重要的垂直运动。<人力资源> * *其他云类型?* *首先,* *附近的其他类型可以掩盖云堆积结构负责闪电* *。强风暴环境中非常普遍,广泛普遍上升运动,尤其是在靠近温暖,会导致厚低级层甲板。有时,在动态的情况下迫使是主导(如与上层风暴系统),或者风暴移动到一个新的环境(如湖泊效应暴风雪),可以厚雾,这样基本上没有什么可以看到!所以在这种情况下,很难真正属性闪电积雨云,尽管这是原因。另外,完整的风暴细胞经常会产生相当复杂的结构:[![supercell][5]][5](Wikipedia, credit Kelvinsong) Due to their shape and motions, **some parts of storms might reasonably be categorized as stratus or altostratus, though they stem from a larger (past or present) cumulonimbus structure**. These stratus-like components include [arcus][6], [incus][7], and [velum][8]. And [mammatus clouds][9] that can occur as part of strong storms are actually a unique example of clouds with sinking air. Even though air in these regions isn't rising much, leftover charge from nearby (or past) updrafts can still bring about lightning. [Anvil crawlers][10] are a common lightning seen in the fairly flat upper regions of storms. Also, while more precise cloud classifications do now set the stages of growing thunderstorms clouds into the cumulonimbus genus, the nimbus prefix [classically meant precipitating][11] (raining/hailing/snowing). **Precipitation reaching the ground is not an absolute requirement for a storm cloud to produce lightning**. So in a loose sense, a cloud doesn't truly have to be a cumulo*nimbus*, at least historically. And of course, as it can do with just about any non-insulating material, **lightning can pass through inactive clouds** on the journey to the ground. **But while these situations may technically satisfy your search for lightning in other clouds types, you're fundamentally right, standard lightning generally derives from cumuloform cloud origins.** [1]: http://www.goes-r.gov/resources/Scipubs/docs/2008/2007JD009598.pdf [2]: https://i.stack.imgur.com/FMEqQ.png [3]: http://hyperphysics.phy-astr.gsu.edu/hbase/electric/lightning2.html [4]: https://electronics.stackexchange.com/questions/10909/lightning-bolt-vs-batteries-a-coulomb-in-everyday-terms [5]: https://i.stack.imgur.com/Lbjtd.png [6]: https://en.wikipedia.org/wiki/Arcus_cloud [7]: https://en.wikipedia.org/wiki/Cumulonimbus_incus [8]: https://en.wikipedia.org/wiki/Cumulonimbus_velum [9]: http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/cld/cldtyp/oth/mm.rxml [10]: https://www.google.com/search?q=youtube%20anvil%20crawlers&ie=utf-8&oe=utf-8#tbm=vid&q=anvil%20crawlers&* [11]: http://www.etymonline.com/index.php?term=nimbus&allowed_in_frame=0
