PARALLEL OUTPUT: An output which has a separate communication path (or wire) for each bit of a digital character This form of transmission makes each bit available simultaneously, and thus results in very fast communications.
ConfluenceA pattern of wind flow in which air flows inward toward an axis oriented parallel to the general direction of flow. It is the opposite of difluence. Confluence is not the same as convergence.
Transverse RollsElongated low-level clouds, arranged in parallel bands and aligned parallel to the low-level winds but perpendicular to the mid-level flow.
A narrow zone across which there is an abrupt change in the horizontal wind component parallel to it. SHORT WAVE A progressive wave of smaller amplitude, wave length, and duration than a long wave.
Polarized light passing through the instrument is indicated by the presence of parallel colored fringes, while unpolarized light results in a uniform field. SAWRS Supplemental Aviation Weather Reporting Station.
As "seen" by Doppler radar, it is the component of motion parallel to the radar beam. (The component of motion perpendicular to the beam cannot be seen by the radar.
Cloud MovementThe direction toward which a cloud is movingCloud StreetsRows of cumulus or cumulus-type clouds aligned parallel to the low-level flow.
Inflow BandsBands of low clouds, arranged parallel to the low-level winds and moving into or toward a thunderstorm. They may indicate the strength of the inflow of moist air into the storm, and, hence, its potential severity.
Geostrophic WindA wind that is affected by coriolis force, blows parallel to isobars and whose strength is related to the pressure gradient (i.e., spacing of the isobars).
Often used to describe cloud formations which appear to be shaped by a smooth flow of air traveling in parallel layers or sheets.
isotherms and height contours are nearly parallel everywhere and directional wind shear is weak.
Under certain conditions cumulus clouds may be arranged in files, cloud streets, oriented approximately parallel to the wind direction. Changes in direction of illumination and in background cause modification of color and of apparent surface relief.
Geostrophic Wind:A straight line wind that moves parallel to the isobars on a surface chart or the contours on an upper air chart.
Glaciers: Glaciers cover about 10% of the Earth's surface.
Overturning, quasi-two-dimensional circulations parallel to mean wind in the layer they occupy in which individual particles move downwind in a helical motion.
Usually, in operational meteorology, references to barotropic systems refer to equivalent barotropic systems - systems in which temperature gradients exist, but are parallel to height gradients on a constant pressure surface.
The basic principles of physics and the Coriolis effect satisfactorily explain that the direction of the wind in the atmosphere is parallel to the isobars.
It is attached to a supercell's general updraft and is oriented roughly parallel to the pseudo-warm front, i.e., usually east to west or southeast to northwest. As with any inflow band, cloud elements move toward the updraft, i.e.
It is a theoretical wind that blows parallel to the thickness lines, for the layer considered, analogous to how the geostrophic wind blows parallel to the height contours. The closer the thickness isopleths, the stronger the thermal wind.
It reached hurricane strength on the 8th, and moved steadlily westward toward the Leeward Islands along the 20° parallel.
Gradient Wind non-geostrophic winds which blow parallel to isobars
Geostrophic winds exist in locations where there are no frictional forces and the isobars are striaght. However, such locations are quite rare.
Facilities for gathering meteorological observations in the other colonies developed in parallel with, but separately from, those in New South Wales. Melbourne's first observatory was built at Williamstown, in 1854.
In hydrologic terms, the longitudinal profile of the surface of a liquid in a non-uniform flow in an open channel, when the water surface is not parallel to the invert owing to the depth of water having been increased by the interposition of an ...
Elongated low-level clouds, arranged in parallel bands and aligned parallel to the low-level winds but perpendicular to the mid-level flow.
- FOOTHILLS -- The foothills are locations between 6,000 and 9,000 feet that parallel a mountain chain.
"Zonal" refers to a wind flow pattern which runs along parallels of latitude (that is easterly or westerly).
Difluence (or Diffluence) A pattern of wind flow in which air moves outward (in a "fan-out" pattern) away from a central axis that is oriented parallel to the general direction of the flow. It is the opposite of confluence.
Wind A natural motion of the air, especially a noticeable current of air moving in the atmosphere parallel to the Earth's surface.
Gradient wind - Wind that flows parallel to the isobars, but non-linearly.
Wind is the natural motion of the air moving parallel to the Earth's surface.
the airflow meanders a long way north and south around the loops of the pattern, crossing many parallels of latitude in a relatively limited longitudinal range: a 'meridional' type; Usually, ...
Grooves or channels in cloud formations, arranged parallel to the flow of air and therefore depicting the airflow relative to the parent cloud.
GEOSTROPHIC WIND A steady horizontal motion of air along straight, parallel isobars or contours in an unchanging pressure or contour field.
Gradient wind The same as geostrophic wind, but blowing parallel to curved isobars or contours. The curved airflow pattern around a pressure center results from a balance among pressure-gradient force, Coriolis force, and centrifugal force.
Upwelling results when winds blowing nearly parallel to a continental coastline transport the light surface water away from the coast.
The tendency of wave crests to become parallel to bottom contours as waves move into shallower waters. This effect is caused by the shoaling process which slows down waves in shallower waters.
Return Period ...
A theoretical horizontal wind blowing in a straight path, parallel to the isobars or contours, at a constant speed. The geostrophic wind results when the Coriolis force exactly balances the horizontal pressure gradient force.

Radar that can measure radial velocity, the instantaneous component of motion parallel to the radar beam (i.e., toward or away from the radar antenna).
Intertropical Convergence Zone (ITCZ): belt of clouds and thunderstorms that runs parallel to the equator and marks where the trade winds of both hemispheres come together.
Gradient wind A theoretical horizontal wind that blows parallel to curved isobars or contours above the friction layer.
Granules A network of huge, irregularly shaped convective cells in the sun's photosphere.
STREAMWISE VORTICITY- The amount of horizontal vorticity parallel to storm inflow.

DRAG - Rearward acting aerodynamic forces tending to slow an aircraft down.
Meridional Flow: Large-scale atmospheric flow in which the north-south component, i.e., flow parallel to the longitude lines or meridians, is much greater than the zonal east-west)component. Compare with zonal flow.

Geostrophic Wind - A wind, usually above a height of 600 meters, that blows parallel to the isobars.
QN-VECTOR - The measurement of convergence on either side of a line parallel to an average of the wind directions on either side of that line. Important for determining the development of squall lines and convergence based storm events.
rotor cloud (sometimes improperly called roll cloud)—A turbulent cloud formation found in the lee of some large mountain barriers, the air in the cloud rotates around an axis parallel to the range; indicative of possible violent turbulence.
