CLIMATES: THE CLOUDS

 Clouds:

    How could you dream on a cloudless day? While contemplating their cotton shapes that sail in the sky, you may be thinking of a hot-air balloon trip or a parachute jump. In reality, clouds are like fog, gray and wet. Despite their infinite variety of shapes, all clouds are made of the same components (water drops and ice crystals ) so small that they float in the air like dust particles. 

 The droplets of the clouds are fine like flour grains: it would take four to cover the width of a hair. It is only when the water drops or ice crystals join together that they become big enough to fall on the ground in rain or snow.

Cloud formation:

    Clouds form when warm air rises and cools to the point of dew. And the temperature at which the water vapour from the air, invisible, begins to condense into droplets. 

 Hot air rises thanks to one of these processes: 

By convection, when it encounters a physical obstacle such as a slope, or when it encounters a cold air mass and it forms a front.

Different types of clouds:

    Although clouds vary greatly from day to day, they can be linked to 10 main types. The first classification of the French Jean-Baptiste Lamarck, in 1802, was replaced the following year by that of the English meteorologist Luke Howard. It distinguishes between hair-like filament clouds (cirrus), dome or ball clouds (cumulus), bench or uniform-layer clouds (stratus), and low and grey clouds (nimbus). Each of these types has different varieties.
