Cumulus arcus clouds have a gust front, [26] and cumulus tuba clouds have funnel clouds or tornadoes. [27] Cumulus pileus clouds refer to cumulus clouds that have grown so rapidly as to force the formation of pileus over the top of the cloud. [28] Cumulus velum clouds have an ice crystal veil over the growing top of the cloud. [19]
Cumulus pileus (WMO genus and accessory cloud) – capped, hood-shaped cumulus cloud. Cumulus praecipitatio (WMO genus and supplementary feature) – cumulus whose precipitation reaches the ground. Cumulus radiatus (WMO genus and variety) – cumulus arranged in parallel lines that appear to converge near the horizon. Cumulus radiatus clouds ...
Trade wind cumulus (or trade cumulus) clouds are formed by cooling and moisture absorption of the dry trade winds over the relatively cold sea surface in the eastern parts of the oceans. [ 2 ] [ 3 ] These are clouds , typically Cumulus humilis or Cumulus mediocris , which are considered as fair weather clouds.
September 19, 2023: Cumulonimbus clouds rise behind wind turbines in Big Spring, Texas. Towering, dense clouds with a flat, anvil-shaped top. Develops from cumulus clouds and can reach great ...
Cumulus clouds have a significant impact on transport of energy and water vapor, and then influence precipitation and climate. In large scale models, cumulus clouds need to be parameterized. Entrainment rate is a key parameter in cumulus parameterization. Henry Stommel was the first to study entrainment rate in cumulus clouds. [4]
Cumulus clouds are formed by the rising air in a thermal as it ascends and cools, until the water vapor in the air begins to condense into visible droplets. When a steady wind is present, thermals and their respective cumulus clouds can align in rows oriented with wind direction, sometimes referred to as " cloud streets " by soaring and glider ...
An air-mass thunderstorm, also called an "ordinary", [1] "single cell", "isolated" or "garden variety" thunderstorm, [2] is a thunderstorm that is generally weak and usually not severe. These storms form in environments where at least some amount of Convective Available Potential Energy (CAPE) is present, but with very low levels of wind shear ...
