Clouds form when water vapour in the air condenses, and for this to happen, the temperature must drop while the pressure remains constant.
In addition, the differences in cloud formation between cloud types are based, in part, on the different condensation temperatures. For example, when condensation occurs at temperatures below freezing, we will have clouds formed by water crystals; whereas, when it occurs at higher temperatures, we will have clouds formed by water droplets.
On the other hand, the air currents present during condensation also play an important role. If there is a light wind, clouds will form in the form of stratus, while if they form in strong winds, we will have clouds with a broad vertical development.
But let’s see how the different types of clouds form in detail.
