Fair Weather Cumulus Clouds
puffy cotton balls floating in the sky
Fair weather cumulus have the appearance of floating cotton and have a lifetime of 5-40 minutes. Known for their flat bases and distinct outlines, fair weather cumulus exhibit only slight vertical growth, with the cloud tops designating the limit of the rising air. Given suitable conditions, however, harmless fair weather cumulus can later develop into towering cumulonimbus clouds associated with powerful thunderstorms.
Fair weather cumulus are fueled by buoyant bubbles of air, or thermals, that rise upward from the earth's surface. As they rise, the water vapor within cools and condenses forming cloud droplets. Young fair weather cumulus have sharply defined edges and bases while the edges of older clouds appear more ragged, an artifact of cloud erosion. Evaporation along the cloud edges cools the surrounding air, making it heavier and producing sinking motion (or subsidence) outside the cloud.

The sky over the Algarve filled with flat-bottomed cumulus clouds.
The shot was taken in Albufeira looking east along the coast.
This year has been a bit different than most. We've had few days of really interesting skies. It's been either totally clear or almost smooth cloudy. This came out of one of those few days.
Between noon to 1PM, these impressive clouds looked like they would develop into significant thunderstorms, but barely a trace of rain fell. While there was plenty of instability, shear winds with altitude were very weak; thus preventing storm development. This cloud mass was about 15 miles to my north.
Strongly sprouting Cumulus with generally sharp outlines and often great vertical extent. The bulging upper part of Cumulus congestus frequently resembles a cauliflower.
Today, thunderstorms should develop from these nascent structures.

These were good looking clouds over the Lakeground in Portishead, but I have applied considerable editing in Photoshop to remove much of the greys from the clouds but not so much from the lower half.
Look at that contrast in colour. Lit by the same sun, but we have an atmosphere to filter the light.
...overhead the Thyrrenian Sea on our way to Malta.
Those colours were that intensive, that even my cheap Ixus could make them seen. ;o)
April is a great month for creating images with strong cloud formations. It’s true what they say about April showers...This was another image that I had in mind following a number of walks around the nature reserve; all I needed was a day when the clouds were at their showery best and the pond was reasonably still. This image was made in colour, but I always had an infra red mono conversion in mind.
