Brrrrrrrrrrr. An Almost-Wordless Wednesday post.
Searching for Fall Color
6 days ago
"This old saying actually has a scientific explanation. It relates to moving high and low surface-pressure weather systems, and the way that the colors in sunlight are scattered differently by dirty and clean atmospheres. This is the explanation of how these phenomena combine to color our sunrises and sunsets." (NOAA link)I read then reread the NOAA page, trying to absorb the explanation of how a low pressure system has a cloudy and cleaner atmosphere causing different scattering of blue vs red light rays, etc. The diagrams helped and I thought I had a grasp on it, right up to the statement:
"A cleaner atmosphere at sunrise or sunset is colored by a mixture of all but the blue colors, giving it a yellowish appearance."What? this week the atmospheric pressure was high, very high, and this is what a sunrise looked like… definitely yellowish. So much for science and folk wisdom - this calls for further study.
