Sunsets and colors
Why are some sunsets so colorful...and others are not?The simple answer to this question is...
Scattering of different wavelengths of sunlight by the particles and water vapor in the air.
A large amount of particles tend to scatter out blue light, giving us a pink to red sunset.
The red sunset can be washed out to whitish by heavy haze or high relative humidity, which will scatter all wavelengths more equally.
More beautiful sunsets!
As for Thursday's weather...in fact the rest of the week:
Night and morning coastal and valley low clouds and patchy dense fog...then clearing to the beaches by afternoon.
Afternoon high temperatures...
60s at the beaches...
70s downtown L.A....
and in the mostly in the 80s to the middle 90s in the valley areas.
