Cumulus clouds are a genus of free-convective low-level cloud along with the related limited-convective cloud stratocumulus. These clouds form from ground level to 2,000 metres (6,600 ft) at all latitudes.

2022年4月27日 · Cumulus clouds appear white when well-lit, but have flattened, darker bases. You’ll see cumulus clouds form on clear, sunny days as the ground heats up. They often appear mid-morning, develop, and vanish as the sun sets.

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. While clouds appear in infinite shapes and sizes, they fall into some basic forms.

2024年12月20日 · Learn about cumulus clouds’ formation process, shape, precise meteorological definition, and description. Cumulus clouds play a role in weather patterns and atmospheric conditions. Cumulus clouds relate to air currents, temperature variations, and moisture levels in the atmosphere.

Cumulus clouds are the clouds that seem to make pictures in the sky. One can make many shapes and designs by watching the clouds pass by overhead. These clouds have a flat bottom and a billowy top. The base of the cloud forms at the altitude at which the rising air cools and condensation starts.

2023年7月10日 · A cumulus cloud forms at the top of a thermal as the water molecules condense (changing state from a gas to a liquid) to form water droplets. When this happens, the warmth given off by the latent heat of condensation heats up the surrounding air causing it to expand and rise further, repeating the cycle and forming the characteristic ...

2025年2月20日 · Altocumulus clouds have several patchy white or gray layers, and seem to be made up of many small rows of fluffy ripples. They are lower than cirrus clouds, but still quite high. They are made of liquid water, but they don’t often produce rain. Altostratus clouds are gray or blue-gray mid-level clouds composed of ice crystals and water droplets.

How do cumulus clouds form? All cumulus clouds develop because of convection. As air heated at the surface is lifted, it cools and water vapour condenses to produce the cloud.

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.

2024年11月22日 · The interconnected processes of convergence, latent heat release, and upward motion drive cumulus cloud formation, playing a crucial role in the water cycle and Earth's climate. Convergence of air masses leads to upward motion, cooling the air and causing condensation of water vapor, releasing latent heat and warming the surrounding air.
