Whatever the Weather
KSAT Meteorologists go beyond the daily forecast to talk about science, weather phenomena, trivia and other fun topics.
WHY ARE SUNRISES/SUNSETS COLORFUL?
It’s all about the kindergarten staple of how light breaks down into different colors — ROYGBIV!
At sunset, when the sun is low on the horizon, the light scatters through more of the atmosphere than during the day. The longer wavelengths of red and orange light remain visible. Blue light, which has a shorter wavelength, is not visible because all of the particles are broken up.
Yes! In the winter, the sun angle is lower which means that sunrises and sunsets last a little longer. There’s also typically less water vapor, or humidity, in the air during the winter. This allows for more vibrant colors and less hazy skies.
A scattering of mid-level and high-level clouds creates colorful sunrises and sunsets. This is because the higher clouds intercept the longer wavelength red and orange light as the sun is setting.
