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.
Stratocumulus cloud consists of large, rounded masses of stratus that form groups, lines or waves.
Everyone looks forward to some summer sunshine but it's worth remembering that when the temperature goes up it can present health risks.
