Red sky at night, shepherd's delight goes the old saying. And that red sky in the evening does usually bring good weather the following day.
There is science to back up the ages old phrase, a red sky is caused by small particles of dust and other airborne particles are trapped in the atmosphere by high pressure.
These particles block light from the sun, scattering or deflecting the light as it passes through the atmosphere.
The shorter wavelengths of blue and violet get scattered more easily leaving more of the longer wavelength red light to make its way across the sky.
Of course, to see this weather phenomenon often it helps when the predominant weather comes from the west which it does in Ireland.
So between you and the sun is the incoming high pressure from the west with dust that scatters shorter wavelengths of light.
Photographers usually enjoy photographing sunsets, so maybe it should be changed to Red sky at night, photographer's delight.
Join me, Panoramic Ireland, to photograph fine sunsets like these all over Ireland.
