Can anyone explain exactly what I’m seeing in this satellite image loop?
It’s mesmerizing and so beautiful. I assume it’s water vapor and that the closest to blue the more there is and the closest to brown the less. The only problem is that it doesn’t really correlate to rain. I think I see what front are but I’d like to hear an explanation by someone who knows.
Is that brown swath the thing which makas a lot of deserts north and south of the equator at that level?

You see the frontal boundaries as lines of moist white/green, backed by the brown as you get the moisture change. The brown is low moisture, white is low to moderate moisture, and greens increasing levels of water vapor.
If you look south to the desert latitudes, you are most likely to see high pressure, which is dry air, subsiding; so in that respect it is a correlation. But at our latitudes the airmasses change constantly .

Did that help?
Thank you. Can he explain why I often seen rain moving in one direction on the radar yet the areas of moisture moving in another direction in the loop?
Does he know which part of the athmosphere this instrument is looking at? I assume it’s from the surface to a great height since there are definitely layers in the image.
