Over deserts, surface air is often so dry that saturation does not occur at all, even when convection is vigorous enough to lift air to substantial heights. When their vertical extent is small, they are called ‘cumulus humilis’ or ‘fair-weather cumulus’. The pouches are created when cold air within the cloud sinks down toward the Earth. Copied. If bubbles rise far enough, the air inside them cools sufficiently for saturation to occur, at a height called the ‘condensation level’.
