  Meridional Fluxes
As the major gradients are meridional, a zonal integration in 5 latitude bands is presented, that shows the pattern of meridional transport (Figure 3,
The ocean/atmosphere hydrologic cycle accounts for a significant portion of the poleward heat transport on the planet.
As discussed later, ocean data alone can be used to estimate the latent heat component of meridional heat transport, thus permitting the specification of a large part of the total planetary energy budget [ Schmitt and Wijffels, 1993].

 Introduction to Physical Oceanography : Chapter 5 - The Oceanic Heat Budget - Meridional Heat Transport
The sum of the meridional heat transport by the ocean and atmosphere together is calculated accurately from the divergence of the zonal average of the heat budget measured at the top of the atmosphere by satellites.
Finally, the meridional derivative of the net flux gives the flux divergence, which must be balanced by heat transport in the ocean.
The atmospheric trans-port is subtracted from the total meridional transport calculated from the top-of-the-atmosphere heat flux to obtain the oceanic contribution as a residual (Figure 5.11).

 Meridional Motion Abstract   (Site not responding. Last check: )
The difference-from-average meridional motions pattern is remarkably similar to the pattern of the magnetic rotation torsional oscillations.
On this is superimposed a cycle-dependent pattern of similar amplitude in which the meridional motions of the small magnetic features are directed away from regions of magnetic flux concentration.
The correspondence between the meridional motions pattern and the torsional oscillations pattern in the magnetic rotation suggests that the latter may be an artifact of the combination of meridional motion and differential rotation.

 meridional (English translation glossary) Turbine,Energy / Power Generation,Tech/Engineering
Meridional in your text has to do with the chord, which is the length of the perpendicular projection of a blade profile onto the chord line.
Once again, meridional, in this case, refers to all possible vertical lines [opposed to horizontal] possible to be drawn on a circumference, or any curve surface.
However, you should stick to the meridional phrasing, as this is standard to the discipline at hand.

En lo que se refiere a la cobertura de saneamiento, en Asia meridional se producen las disparidades más graves del mundo entre las zonas urbanas y rurales.
Y mientras que el número de personas sin acceso al saneamiento en las zonas urbanas aumentó de 139 millones en 1990 a 153 millones en 2004, hay más del doble de posibilidades de que las poblaciones urbanas tengan acceso al saneamiento, en detrimento de las rurales.

 meridional | | Dictionary & Translation by Babylon
Meridional is a geographic term that means along a north-south direction, or relative to a meridian (opposite: zonal, east-west).
In the atmospheric sciences, the meridional flow is the flow between the poles, or between the equator and the poles; and the meridional coordinate is usually denoted by y, and the meridional component of the wind speed by v.

 Johnson and Moore -- Pacific Subsurface Countercurrents -- Mean meridional sections
This spreading is discernable at 165°E and stronger at 155°W. At 110°W the EUC is shallow and south of the equator, where isotherms dip near 1°S. This southern displacement from the equator has been shown to be the result of meridional wind forcing (Philander and Delecluse 1983).
The southern subsurface S maximum, water subducted in the southern subtropics where evaporation dominates over precipitation, is prominent in all three sections and strongest at 155°W. North of the equator, surface S decreases to the east under the intertropical convergence zone, a region of high precipitation (Ando and McPhaden 1997).
The lower limit is near the reference surface and the upper limit is imposed to isolate the north SSCC from the eastward-flowing NECC.

 Estimates of meridional ocean heat transports (Trenberth and Caron, 2001)
In this paper we present new results of meridional ocean and atmosphere heat transports which are also based upon energy balance computations of the atmosphere, adjusted to fit physical constraints, using the reanalyses.
Nevertheless, this achievement by two groups is in effect a reconciliation of the atmospheric and oceanic modules as to what the meridional heat transport by the atmosphere and the ocean should be, and so this provides measures of these vital quantities which have heretofore been quite uncertain.

 The Science of Abrupt Climate Change : Weather Underground   (Site not responding. Last check: )
The Meridional overturning circulation transports a tremendous amount of heat northward, keeping the North Atlantic and much of Europe up to 9°F (5°C) warmer, particularly in the winter.
Other sudden shut downs of the Meridional overturning circulation observed in ice core and ocean sediment records are not thought to be due to sudden melt-water floods into the North Atlantic.
Most climate models used to study this problem show a slowing of the Meridional overturning circulation of 20% - 50% over the next century; a full shutdown would take a relatively extreme 9°F (5°C) warming of the climate, which is not expected to happen this century.

To provide quarterly reports on the state of the oceans meridional oceanic heat transport in the Atlantic Ocean.
This heat transport is directly related to the role that this basin plays in the meridional overturning circulation (MOC) and is an important benchmark for integrated air-sea fluxes and numerical model performance.
AOML collects XBT data on two lines spanning the subtropical oceans: in the North Atlantic since 1995 along AX7 running between Spain and Miami, Florida and in the South Atlantic since 2002 along AX18 between Cape Town, South Africa and Buenos Aires, Argentina.

 Collapse and rapid resumption of Atlantic meridional circulation linked to deglacial climate changes : Abstract : Nature
Th, a kinematic proxy for the meridional overturning circulation, in a sediment core from the subtropical North Atlantic Ocean.
We find that the meridional overturning was nearly, or completely, eliminated during the coldest deglacial interval in the North Atlantic region, beginning with the catastrophic iceberg discharge Heinrich event H1, 17,500 yr ago, and declined sharply but briefly into the Younger Dryas cold event, about 12,700 yr ago.
Th record indicates that rapid accelerations of the meridional overturning circulation were concurrent with the two strongest regional warming events during deglaciation.

 Meridional Overturning
Derived from simulations with BRIOS_1.0, spatial and temporal separation of the Southern Ocean meridional overturning into Atlantic and Indian-Pacific sectors south of 66°S and into summer (DJF) and winter (JAS) months, respectively, shows that the densest water is found year-round on the the Ross Sea continental shelf (Fig.
However, this dense water does not reach the deep basins as the admixture of lighter bottom water between 72°S and 68° seems to erase the high-density signal of the Ross Sea outflow.
Bold solid lines represent the minimum (upper) and maximum (lower) density value for each latitudinal band.

Let’s look at the zonal mean circulation first and then we will move on to the mean meridional circulation.
The ageostrophic mean meridional circulation is constrained by the thermal wind equation: the relationship between the zonal mean wind and the potential temperature distribution.
But small departures of the mean zonal wind from geostrophic balance cause a mean meridional circulation, thus maintaining the thermal wind balance.
