cumuliform clouds characteristics

They're found in the middle layer of the troposphere, lower than cirrocumulus and higher than their cumulus and stratocumulus counterparts. In addition, cloud electrification occurs within cumulonimbus clouds due to many collisions between charged water droplet, graupel (ice-water mix), and ice crystal particles, resulting in lightning and thunder. They are typically known as rain clouds in the summer and spring and also as clouds of snow in the winter. The picture on the left, taken by Jimmy Deguarra in Oakhurst near Sydney, Australia, shows the early stages of the formation of an anvil. Altocumulus vs Stratocumulus.

Cumulus clouds are often precursors of other types of clouds, such as cumulonimbus, when influenced by weather factors such as instability, moisture, and temperature . Also known as scud. Nam lacinia pulvinar tortor nec facilis ante, dapibus a molestie consequat, ultrices ac magna. Advisory/Warning Criteria, Radar If enough atmospheric instability, moisture, and lift are present, then strong updrafts can develop in the cumulus cloud leading to a mature, deep cumulonimbus cloud, i.e., a thunderstorm producing . Wall clouds take on many shapes and sizes. The base of each cloud is often flat and may be only 1000 meters (3300 feet) above the ground. Stratiform clouds at temperatures of -10°C to -20°C are most conducive to its formation. They also may line up in streets or rows of clouds across the sky denoting localized areas of ascent (cloud axes) and descent (cloud-free channels). Weather Safety Rules Unlike cirrus, cirrostratus clouds form more of a widespread, veil-like layer (similar to what stratus clouds do in low levels). In semiarid and arid regions, cumuliform cloud may have a much higher base. Nam risus ante, dapibus a molestie consequat, ultrices ac magna. Just like cumulus they have a large and massive appearance but they give the impression of mountain cliffs whose tops are like a large mushroom. Stratocumulus                                                    NImbostratus. Spotter Training Nam lacinia pulvictum vitae odio. Lorem ipsum dol, usce dui lectuamet, consectetur adipiscing elit. Like cirrocumulus, altocumulus may align in rows or streets of clouds, with cloud axes indicating localized areas of ascending, moist air, and clear zones between rows suggesting locally descending, drier air. Their presence can reflect the arrival of a warm front or a storm. Cirrus clouds are wispy, feathery, and composed entirely of ice crystals.

They frequently indicate the approach of a warm front and may thicken and lower into stratus, then nimbostratus resulting in rain or snow. Cumulus means 'pile' in Latin, and nimbus means 'rain cloud.' These describe a cumulonimbus cloud perfectly, because it grows up vertically like a billowy pile, and these clouds usually bring rain . Some exhibit strong upward motion and cyclonic rotation, leading to tornado formation, while others do not rotate and essentially are harmless. Also, during the summer and spring season, they appear at the dawn and disappear later, reflecting a good weather. Shape: cauliflower of fluffy. Cumulus clouds are low-level clouds, generally less than 2,000 m (6,600 ft) in altitude unless they are the more vertical cumulus congestus form.

A quantitative introduction to atmospheric science for students and professionals who want to understand and apply basic meteorological concepts but who are not ready for calculus. Clouds of vertical development (fair-weather cumulus, cumulus-congestus, cumulonimbus) cannot be classified as high, middle or low because they typically occupy more than one of the above three altitude markers. They are formed by the convective process. Science and Technology Description & Characteristics. Questions? These clouds are formed by very small droplets of water and / or ice crystals (2 to 200 microns in diameter) obtained by the condensation of water vapor from the atmosphere around tiny particles (dusts, aerosols, …) called condensation nuclei. Cumulus clouds forming at what is considered a middle altitude of 6500 - 18 000 feet are called altocumulus clouds and are coupled with precipitation. Initial lifting to trigger a cumuliform cloud may be the same as that for lifting stable air. The fluffy, cauliflower-shaped cumulus is one of the most common and distinctive types of cloud.
