The movement of wind and water over the earth’s surface, and varying localised temperature and air pressure conditions, create a range of weather conditions. Broadly speaking, air migrates from high pressure zones into low pressure zones, giving rise to warm air rising and cold air sinking. As the warm air rises, it takes up moisture; but the higher it goes, the colder it becomes. Eventually, the moisture begins to condense as clouds, and, as they say, ‘what goes up, must eventually come down’.
Clouds
Clouds are formed from millions of tiny water droplets which are cooled in the atmosphere. They also contain microscopic dust particles, so as moisture rises, expands and cools, any vapour it holds condenses onto the surface of these dust particles. This results in small water droplets…
