Nimbostratus Clouds

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.

Stratus Clouds

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.

Altostratus Clouds

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.

Cirrostratus Clouds

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.
