MINNEAPOLIS – Expect spectacular sunsets and sunrises this week because of smoke from Canadian wildfires, the National weather Service said. Further good visual news. albeit due the disastrous fires, is that the smoke is remaining aloft. Hence there is nil effect on surface air quality. Ask the meteorologists what’s going on, they’ll get technical. It’s that low-horizon sun rays are slowed and bent by smoke particle, which creates a longer wavelength than the usual sky blue or violet.
Thanks, Canada. Sun rays take longer to travel through smoke. In the process they come through in rich, warm colors.
