A big ridge in the jet stream is transporting western wildfire smoke our way next couple of days. Most of the smoke is in the upper atmosphere and won't dramatically impact air quality, but the sky may look a little milky and the sunrise and sunset may be enhanced.But why the red/orange?
As we cut-n-paste from another TV station: "The smoke filters out shorter wavelengths of light, leaving mostly red and orange wavelengths to shine through and be seen by the naked human eye."
