搞不懂这种非常奇特的云是如何形成的，肯定不是人为的。花MM快来接靴子哈。

一种大气中的波动现象。 from baidu.com 波状云 波状云是波状高积云的简称 波状云形成原理：空气中有波状运动时，如果云层比较稳定，水汽充沛， 在波动的作用下可形成波状云。云的外形特征与空气的波状运动紧密相联。空气沿波峰上升冷却凝结成云，沿波谷则因下沉增温无云形成，或云滴蒸发而云变薄，形成波状排列的云条或云层。云轴的排列与上下层风的向量差一致。例如在测站的上空，低层风速为V1，高层风速为V2，风的向量差为△V，则云轴沿△V的方向排列。如果被动同时产生在两个不同方向时，由于这两个波动互相干扰，云便分裂为孤立的扁球状或块状；排列成群、成行，很有规则。 更多类似的云：https://sxsqxj.gov.cn/list.aspx?cid=136 参看 https://en.wikipedia.org/wiki/Wave_cloud https://www.weatherquestions.com/What_causes_wave_clouds.htm 看看从wikipedia来的照片     本贴由[大清太平]最后编辑于：2007-10-10 19:33:53   ---

https://www.weatherquestions.com/What_causes_wave_clouds.htm While "wave cloud" is not a specific type of cloud, a few clouds do sometimes form wave patterns. One reason for wave patterns in clouds is when they form in a stable layer, that is a thin layer of the atmosphere where the temperature doesn't decrease very much with height, or even increases with height. Any disturbance in this layer can cause waves of air to move along it, like water waves in a pond. If the layer happens to be humid enough, then where the air is flowing up a crest of the wave, a cloud forms, and where it is flowing down the crest, the cloud evaporates. This leads to the wave structures, as are pictured above. Another way that wave clouds can form is where air flows over a mountain or hill. If a cloud forms on this wave, it is called a "lenticular" (which means "lens-shaped") cloud, which has a very smooth, symmetric appearance.   ---
