Convergence Associated With Cyclones extra-tropical and tropical cyclones
Both extra-tropical and tropical cyclones, like this hurricane, can cause air to rise. This type of lifting is different from the lifting produced along frontal boundaries.
Moisture Convergence - A measure of the degree to which moist air is converging into a given area, taking into account the effect of converging winds and moisture advection.
The Intertropical convergence zone (ITCZ), also known as the Intertropical Front or the Equatorial Convergence Zone, is a belt of low pressure girdling Earth at the equator.
convergence line"1. (Sometimes called asymptote of convergence.) Any horizontal line along which horizontal convergence of the airflow is occurring.
Convergence - A contraction of a vector field; the opposite of divergence. Convergence in a horizontal wind field indicates that more air is entering a given area than is leaving at that level.
Convergence - Coming together; "piling up" of mass. Surface convergence occurs in association with rising air whereas upper-level convergence is associated with subsidence.
Convergence: The horizontal coming-together of air that can lead to lifting.
Crepuscular rays: Beams of light from the sun caused by a combination of shadows and scattering. These light and dark bands usually occur at twilight.
Convergence: The flow of the wind resulting in a horizontal inflow of air into a region. Convergence of winds near the surface are associated with upward motion known in meteorology as convection. The opposite of convergence is divergence.
CONVERGENCE- CONV. A 1-D process in which higher momentum air moves into lower momentum air.
CORIOLIS- An apparent force caused by the earth's rotation. The Coriolis force is a maximum at the poles and a minimum at the equator.
CONVERGENCE- A 1-D process in which higher momentum air moves into lower momentum air.
Convergence - The condition that exists when the wind distribution within a given region results in a net horizontal inflow of air into the area.
Convergence - the net inflow of air into a region, typically caused by horizontal wind motion; the opposite of divergence ...
convergence—The condition that exists when the distribution of winds within a given area is such that there is a net horizontal inflow of air into the area.
CONVERGENCE Wind movement that results in a horizontal net inflow of air into a particular region. Convergent winds at lower levels are associated with upward motion. Contrast with divergence.
convergence - 1. The contraction of a vector field; also, a precise measure thereof. Mathematically, convergence is negative divergence, and the latter term is used for both. (For mathematical treatment, see divergence).Compare confluence. 2.
Convergence - A contraction of a vector field, usually said of winds; the opposite of divergence.
Convergence
Consider an area on the earth's surface. On the sides which face the wind, air will flow into the area, while on the other sides air will flow out.
Convergence: a net flow of air into a given region. Compare divergence.
Convergence
In meteorology the act of a net inflowing of air. An example is at the base of a developing depression.
Coriolis Effect ...
CONVERGENCE - Air that comes together at a given point in the atmosphere. Important for convective initiation.
Sea Breeze Convergence Zone
The zone at the leading edge of a sea breeze where winds converge. The incoming air rises in this zone, often producing convective clouds.

Puget Sound Convergence Zone (PSCZ) A situation where wind forced around the Olympic Mountains converges over the Puget Sound.
Intertropical convergence zone ((ITCZ))(6)
The boundary zone separating the northeast trade winds of the Northern Hemisphere from the southeast trade winds of the Southern Hemisphere.

Inter-tropical Convergence Zone. The region where the northeasterly and southeasterly tradewinds converge, forming an often continuous band of clouds or thunderstorms near the equator

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.
Intertropical convergence zone (ITCZ) Discontinuous belt of thunderstorms paralleling the equator and marking the convergence of the Northern and Southern Hemisphere surface trade winds.
Inter Tropical Convergence Zone
A relatively narrow zone of persistent thunderstorms in tropical waters. It marks the meeting or convergent point of winds originating from both the northern and southern hemispheres.
2) Locate areas of convergence/divergence (when generated along a radial; and
3) Analyze areas of rotation (when generated from one AZRAN to another).
ITCZ: Intertropical Convergence Zone. Trough located next to the equator, delimiting the convergence zone of the air that moves from the subtropical regions of both hemispheres towards the equator.
Confluence is not the same as convergence. Winds often accelerate as they enter a confluent zone, resulting in speed divergence which offsets the (apparent) converging effect of the confluent flow.
Due to the imbalance of heating between land and water, a region of maximum upward motion or convergence occurs by mid-afternoon in the summer some 10 to 15 miles inland.
convergence The quasi-horizontal flow of a fluid toward a common destination from different directions.
It is the opposite of convergence. Divergence at upper levels of the atmosphere enhances upward motion, and hence the potential for thunderstorm development (if other factors also are favorable).

It is a plume-like object that extends from the Intertropical Convergence Zone (ITCZ) northward or southward into the higher latitudes. It is usually located over a 850 to 700 mb theta-e ridge axis.
Dines Compensation states that net mass convergence into a given column of air must be balanced by a net mass divergence from the same column of air.
A convergence occurs at about 200 mb that produces cirrus that is sucked into the centre of the vortex, making the relatively clear eye of 10-80 km radius, averaging about 35 km.
The expansion or spreading out of a vector field; usually said of horizontal winds. It is the opposite of convergence.
Divergence A measure of the expansion or spreading out of a vector field; usually said of horizontal winds. It is the opposite of convergence.
A product of downdrafts, it is relatively cold and often has the characteristics of a different air mass. Convergence along the leading edge of a bubble high may help form additional thunderstorms. Related term: meso high ...
(NB: Forced ascent comes about in several ways: frontal ascent due to large-scale air motion within frontal systems, with of course adjacent descent; convergence into an area of low pressure - the converging air can't go down near the surface - it ...
Tornado formation appears to be related to the convergence (meeting) of air occurring underneath a developing cumulonimbus cloud. The swirling air is then tilted upwards to form the tornado.
the entire sky and be up to several thousand feet thick, they are relatively transparent, as the sun or the moon can easily be seen through them. These high-level clouds typically form when a broad layer of air is lifted by large-scale convergence.
