The sky appears blue to the human eye as the short waves of blue light are scattered more than the other colours in the spectrum, making the blue light more visible.
The classification of clouds into types was first proposed by Luke Howard in 1802 and we largely use the same system today splitting clouds into three main types - stratus, cumulus and cirrus.
Cirrocumulus are a relatively rare cloud forming ripples which may resemble honeycomb.
During the winter months, extreme weather conditions can make driving more difficult and potentially hazardous.
