The list of cloud types groups all genera as high (cirro-, cirrus), middle (alto-), multi-level (nimbo-, cumulo-, cumulus), and low (strato-, stratus). These groupings are determined by the altitude level or levels in the troposphere at which each of the various cloud types is normally found.

2022年4月27日 · Stratus clouds are sheets or layers of clouds. They can produce an overcast day or light rain or snow. Cirrus clouds are white wisps high in the sky. Nimbus clouds are either cumulus or stratus clouds that produce precipitation. Rain and snow clouds tend to …

2023年3月28日 · From his Essay of the Modifications of Clouds (1803), Luke Howard divided clouds into three categories: cirrus, cumulus, and stratus, plus a fourth special type, nimbus. The Latin word "cirro" means curl of hair. Composed of ice …

2025年2月27日 · Cirrus clouds are wispy, feathery, and composed entirely of ice crystals. They often are the first sign of an approaching warm front or upper-level jet streak. Unlike cirrus, cirrostratus clouds form more of a widespread, veil-like …

2024年4月26日 · Clouds are classified into three main groups: cirrus, stratus, and cumulus. Cirrus clouds are wispy, curly, or stringy. They are found high in the atmosphere—typically higher than 6,000 meters (20,000 feet)—and are usually made of ice crystals. Cirrus clouds usually signal clear, fair weather.

As a warm front approaches, cirrus clouds tend to thicken into cirrostratus, which may, in turn, thicken and lower into altostratus, stratus, and even nimbostratus. Finally, cirrocumulus clouds are layered clouds permeated with small cumuliform lumpiness.

2023年10月12日 · Howard actually named three main types — cirrus, cumulus, and stratus — with a fourth special type called nimbus. The International Cloud Atlas expands upon this original classification system...

Stratus clouds look like flat sheets of clouds. These clouds can mean an overcast day or steady rain. They may stay in one place for several days. Click on the image to view the large version. Cirrus clouds are high feathery clouds. They are up so …

The main types of clouds by shape are cirrus, cumulus, and stratus. These categories encompass the basic visual characteristics of clouds and help classify them into more specific subtypes. While cirrus clouds are thin and wispy, cumulus clouds are fluffy and have a puffy appearance, and stratus clouds form in uniform, continuous layers.

2024年11月22日 · In this guide, we’ll explore the 4 main types of clouds: cumulus, stratus, cirrus, and nimbus, breaking it down so anyone can grasp it. What Are Clouds? In simple terms, clouds are collections of tiny water droplets or ice crystals floating in the atmosphere.
