Australian Weather Calendar - August 2014

August photograph by Donna Munro

Clouds painted with sunlight's warmer palette

Clouds at sunrise and sunset are coloured orange and red because they are lit by sunlight that has travelled further through the atmosphere than at other times of the day. Parts of the light spectrum are scattered or lost as they travel through the atmosphere—first the blues and purples are scattered, then the greens, leaving only the red, orange and yellow hues. For someone who had never taken a photo of the weather before, pensioner Donna Munro's first attempt was pretty impressive in capturing this sunset in 2012. Donna, from Spreyton in the north of Tasmania, says her picture was 'just a one-off'.
