Here is a catch -all topic for a unique and ubiquitous series of thin and dynamic atmospheric layers, the metallic vapor layers. I thought there might already be a topic, but there was no sign of one. I am still learning about this topic and you may be too. Layers of shifting metallic elements that exist at mesospheric heights where planetary and gravity waves exist seem to be a significant contributing and modulating effect on weather, both its predictable patterns and anomalies. Some of the va
