Convective clouds: A cloud that results from convection.
Convergence: The horizontal coming-together of air that can lead to lifting.
Convective Clouds: Clouds formed atop rising air columns. Cumulus clouds are convective clouds.
Convective Clouds The vertically developed family of clouds are cumulus and cumulonimbus. The height of their bases range from as low as 1,000 feet to a bit more than 10,000 feet.
Convective clouds and heavy rains are fueled by increased buoyancy of the lower atmosphere resulting from heating by the warmer waters below.
CAP CLOUDS - Convective clouds developing in neutral or de-stabilizing air over a pre-existing thermal from a forest fire or other similar heat source.
HAIL Precipitation that originates in convective clouds, such as cumulonimbus, in the form of balls or irregular pieces of ice, which comes in different shapes and sizes.
The incoming air rises in this zone, often producing convective clouds.Sea Breeze FrontThe leading edge of a sea breeze, whose passage is often accompanied by showers, a wind shift, or a sudden drop in temperature.
>> Multi-cell thunderstorms: Whenever wind shear is present in an unstable atmosphere, the developing convective clouds will be tilted to a greater or lesser extent.
The second type is known as a multicell cluster composed of a group of convective clouds that move together as a single unit. There may be multiple updraft and downdraft segments, highly variable rates of rainfall, and some moderate hail.
Landspouts form during the growth stage of convective clouds by the ingestion and tightening of boundary layer vorticity by the cumuliform tower's updraft.
hail - Precipitation in the form of balls or irregular lumps of ice, always produced by convective clouds, nearly always cumulonimbus. An individual unit of hail is called a hailstone.
Most convective clouds are driven by positive buoyancy, with virtual temperature greater than the environment, but clouds with precipitation, evaporation, and/or melting can produce negatively buoyant convection. See slantwise convection. 3.
Altocumulus Castellanus (ACCAS) They are middle level convective clouds and possibly they should be classified as clouds with extensive vertical development. They are composed of mainly water vapor.
Precipitation, often short-lived (but may last half an hour) and heavy, falling from convective clouds. Usually begin and end suddenly.
Sleet
Generally refers to a mixture of rain and snow or falling snow that is melting into rain.
cumuliform—A term descriptive of all convective clouds exhibiting vertical development in contrast to the horizontally extended stratiform types.
Hail - precipitation in the form of rounded balls of ice, always formed in convective clouds, nearly always thunderstorms ...
Eye of a Tropical Cyclone
The relatively clear and calm area inside the circular wall of convective clouds, the geometric center of which is the center of tropical cyclone.
The zone at the leading edge of a sea breeze where winds converge. The incoming air rises in this zone, often producing convective clouds.
Sea Breeze Front ...
Continental Polar air forms over the high latitudes of North America, Europe and Asia. This air mass has low surface temperatures, is very stable, with low moisture. It contains convective clouds, turbulence, good visibility, rain and snow showers, ...
Meteorologists refer to vertical motions as convective. Horizontal motions are advective. Also used to denote the presence of cumulus clouds (also known as convective clouds); most often refers to instability.
Temperature and dew point close at about 4oF for each 1,000 feet rise in altitude. When air is unstable, convective clouds may form; fog forms at the surface where the ground level is at or above the condensation level.
This type of weather is only found in the hearts of the trade wind areas. Towards the equator the heating of the seawater causes the air to become unstable and form large convective clouds like cumulus congestus.
