Cumulus are low, puffed, convective clouds formed by surface heating and uplift. They have flat bases and variable tops. The name was coined in the early 19th century and is widely familiar in art, and literature.
Nimbostratus are thick, opaque, precipitating layers of cloud that produce steady rain or snow. They form in broad lift regions and may span much vertical depth. The name comes from later refinements to Howard’s schema and serves as a core genus in modern meteorology.
Stratocumulus are low, clustered, lumpy cloud layers that bridge the gap between stratus and cumulus. They form via shallow convection and mixing. Their name arose from 19th- and 20th-century cloud taxonomy, and they are familiar in weather forecasts and landscape art.
Murus clouds, commonly referred to as wall clouds, are dramatic, vertically oriented cloud features that form beneath the base of a severe thunderstorm, usually a supercell cumulonimbus cloud. They are characterised by a concentrated, lowering base that can rotate and serve as a precursor to tornado formation.
Stratus are low, uniform cloud sheets often producing drizzle or mist. They form under stable, humid conditions with minimal uplift. The name has classical roots and features in everyday speech and literary descriptions of dull or overcast skies.
Altocumulus are mid-level, patchy, somewhat convective clouds forming in moist layers with slight instability. They often show patterns or grouping. Their name originated in the 19th-century expansion of cloud classification, though clouds of this sort were long observed in art and literature.
Altostratus are mid-level, uniform grey sheets that often cover the sky and may dim sunlight or bring light precipitation. They are created by gentle lifting of moist air and were formally classified during the development of modern cloud atlases.
Cirrocumulus are small, finely textured clouds of ice crystals in a high layer, appearing as ripples or patchwork. They form under weak vertical motion. The term was formalised in 19th-century cloud atlases, and the “mackerel sky” phrase has long circulated in folk weather lore.
Cirrostratus are high, veil-like ice-crystal clouds that spread diffusely and often produce halos around the sun or moon. They form under gentle ascent near warm fronts. Their name solidified in standard cloud atlases from the late 19th century, and they feature in halo folklore.
Incandescent contrails are a type of contrail that form not from engine exhaust, but from rapid pressure drops around an aircraft’s wings which cause water vapor in the atmosphere to condense and freeze. When lit by the sun, these wake contrails can appear unusually bright or glowing like a rainbow. Their origin is purely aerodynamic and optical: no chemicals are sprayed, and the effect arises from ice crystals interacting with sunlight.
Not all clouds fit neatly into the ten main genera. Some appear as distinctive features or as by-products of atmospheric processes. These forms provide visual evidence of atmospheric motion or turbulence and are important signals for weather observers and forecasters.
Geoengineering conspiracy theories range from chemtrail claims to ideas about weather weapons, artificial suns and nanoparticle grids. Although diverse, each misunderstands physics, atmospheric science and energy limits. This article examines the origins and scientific impossibilities behind these narratives to provide a clear evidence based perspective.
