Single Cell Thunderstorms also known as pulse thunderstorms Single cell storms typically do not produce severe weather and usually last for 20-30 minutes.
A convection cell is a phenomenon of fluid dynamics which occurs in situations where there are temperature differences within a body of liquid or gas.
cell - In radar usage, a local maximum in radar reflectivity that undergoes a life cycle of growth and decay.
Cell Convection in the form of a single updraft, downdraft, or updraft/downdraft couplet, typically seen as a vertical dome or tower as in a cumulus or towering cumulus cloud.
CELL- An individual thunderstorm (often referred to as such on radar). CELSIUS- A temperature scale using 0 as freezing and 100 as boiling at standard sea-level atmospheric pressure and temperature. CG- Cloud to Ground lightning ...
Dew Cell: A hygrometer used to determine the dew point temperature directly.
Ferrel Cell - in the general circulation of the atmosphere, the name given to the middle latitude cell marked by sinking motion near 30 degrees and rising motion near 60 degrees latitude Fine Line - see thin line ...
Multi-cell(ular) Thunderstorm - A thunderstorm consisting of two or more cells, of which most or all are often visible at a given time as distinct domes or towers in various stages of development.
Single Cell Thunderstorm This type of thunderstorm develops in weak vertical wind shear environments. On a hodograph, this would appear as a closely grouped set of random dots around the center of the graph.
Hadley cell A direct thermally-driven and zonally symmetric large- scale atmospheric circulation first proposed by George Hadley in 1735 as an explanation for the trade winds.
Hadley Cell - The thermally driven circulation system of equatonal and tropical latitudes consisting of two convection cells, one in each hemisphere.
Hadley cell Thermally-driven air circulation in tropical and subtropical latitudes of both hemispheres resembling a huge convective cell with rising air near the equator and sinking air in the subtropical anticyclones.
CELL - A precipitation element, usually associated with convective precipitation such as thunderstorms. The term is also applied to an individual storm or weather system component as a low-pressure (or high-pressure) cell.
Single cell thunderstorms which produce brief periods of severe weather (3/4 inch hail, wind gusts in the excess of 58 miles an hour, or a tornado). Pulse Storm ...
>> 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 term "cell" also is used to describe the radar echo returned by an individual shower or thunderstorm. Such usage, although common, is technically incorrect.
Resolution Cell The smallest unit of area in an image of discrete elements. The area represented by a pixel.
Dew cell An instrument used to determine dew point. Dew point (or dew-point temperature) The temperature to which a sample of air must be cooled, while the mixing ratio and barometric pressure remain constant, ...
type of forcing mechanism, synoptic-scale or otherwise, the existence of true air-mass thunderstorms is debatable; therefore, the term is somewhat controversial and should be used with discretion. Also, see Popcorn Convection and Single Cell ...
It registers the change in the shape of an evacuated metal cell to measure variations on the atmospheric pressure. The aneroid is a thin-walled metal capsule or cell, usually made of phosphor bronze or beryllium copper.
It consists of an aneroid cell which responds to atmospheric air pressure. A pen is attacted to the cell through a series of gears and levers. This pen rides on a chart. The pen has ink on and it produces a trace on the chart.
An ozonesonde is an electrochemical cell and radio transmitter attached to a hydrogen filled balloon that can reach a height of about 35km. Air is drawn through the cell by a small pump.
hurricane- an extremely low-pressure, destructive weather cell of tropical origin with wind speeds in excess of 74 miles per hour (119 kilometers per hour). Hurricanes causes widespread flooding and wind damage in North America and the Caribbean.
Frost Damage Damage to vegetation occurring when the water that is part of the cell structure of the plant solidifies, bursting cells' walls and deteriorating the plant materials.

Pulse Severe Thunderstorms These are single cell thunderstorms which produce brief periods of severe weather (3/4" hail, wind gusts in the excess of 58 miles an hour, or a tornado).
Downdraft Downward moving air, usually within a thunderstorm cell. Drainage basin A fixed geographical region from which a river and its tributaries drain water.
"Vorticity" is defined as positive if it rotates counterclockwise about a low pressure cell (storm system) in the northern hemisphere. Vorticity about a high pressure cell with clockwise rotation in the northern hemisphere is defined as negative.
Convection - Air moving up and down in a quasi-circular flow, called a cell.
ceilometer—A cloud-height measuring system. It projects light on the cloud, detects the reflection by a photoelectric cell, and determines height by triangulation.
MCS - Mesoscale Convective System. A grouping of storms, either in a line or a circular cluster that has organization larger than each individual cell.
They generally are less likely to be severe than other types of thunderstorms, but they still are capable of producing downbursts, brief heavy rain, and (in extreme cases) hail over 3/4" in diameter. Also, see Popcorn Convection and Single Cell ...
Most of the rain produced by the thunderstorm evaporates into relatively dry air beneath the storm cell. May also be referred to as "dry lightning".
