Cumulus congestus cloud any rain may be accompanied by thunderstorms. Turkey tower is a slang term for a narrow, individual towering cloud from a small cumulus cloud which develops and suddenly falls apart. Sudden development of turkey towers could signify the breaking or weakening of a capping inversion. Cumulus congestus cloud Cumulus congestus clouds, also known as towering cumulus, are a form of cumulus cloud that can be based in the low or middle height ranges. They achieve considerable vertical development in areas of deep, moist convection. They are an intermediate stage between cumulus mediocris and cumulonimbus. Cumulus congestus clouds are characteristic of
Cloud physics of about 0.002 mm (0.00008 in). The droplets may collide to form larger droplets, which remain aloft as long as the velocity of the rising air within the cloud is equal to or greater than the terminal velocity of the droplets. For non-convective cloud, the altitude at which condensation begins to happen is called the lifted condensation level (LCL), which roughly determines the height of the cloud base. Free convective clouds generally form at the altitude of the convective condensation level (CCL). Water vapor in saturated air is normally attracted to condensation nuclei such as salt particles that are small
