Condensed water or ice. When the sun heats the ground, warm air starts to evaporate and rise towards the sky. Once these water vapor particles cluster together, a cloud is formed. If it is joined by more water crystals and keeps growing, it will eventually reach us on the ground as rain or snow. Otherwise, the clouds simply evaporate into thin air.
Even though all the beautiful cloud formations might seem random and indescribable to you, there’s a whole cloud classification system that’s uniform worldwide. Luke Howard, a British manufacturing chemist, and an amateur meteorologist were the first to introduce a nomenclature system for clouds back in 1802. Today clouds are categorized based on their shape, altitude, the process of formation, and other features.
Here’s a selection of some stunning cloud photos – we bet that among them you’ll find some weird cloud formations that you’ve never actually seen before!
