§   Develops from mature cumulus

§   Cloud base below 2000 m, while cloud top can develop to 6000 m above ground or even reaching the tropopause

§   Grows vertically and typically covers an area of a few kilometres in diameter

§   Usually associated with showery or adverse weather, including heavy rain, lightning, thunderstorms, rainstorms, hailstorms or even tornadoes

§   Commonly seen in the summer

§   Cloud base between 300 and 1000 m

§   Grows vertically with sharp outlines and dome-shaped tops

§   Often detached from one and other, and blue sky is often seen between clouds

§   With strong convective activity, mature cumulus produces showers or even develop into cumulonimbus

§   Usually thin with a depth of a few hundred metres, and the horizontal coverage often exceeds several kilometres

§   Occurs in connected patches or undulating layers, or composed of rounded masses or rolls at one or more levels

§   Clear outline at cloud base with very little or even no space between clouds
