Sentences with phrase «eddy vertical»

The importance of stationary - eddy vertical motions at 850 hPa arises as vertical motions bring moisture from the boundary layer to a mean condensation height of about 850 hPa (Wills and Schneider 2015).

The reduction of stationary - eddy vertical velocities limits the increase in strength of the zonally anomalous hydrological cycle that would otherwise result from the increased atmospheric moisture content with warming.

«The central approximation of the derivation is to relate the eddy latent heating rate (or more precisely ω ↑ «-RRB- to the eddy vertical velocity»

Los Alamos researchers created models to quantify the horizontal and vertical structure of mixing in the ocean and its dependence upon eddy velocities.

In the ocean, one can have relatively fast eddy diffusion coefficients, both vertical and horizontal, and then also have slower conductive diffusion coefficients.

And the Ferrell - to - Polar Cell boundary at 55 - 60 ° North is something of a statistical thing, not exactly a vertical curtain, and there are eddies (alias weather systems) that wander around.

[7] The Eddies produced cause an increase in vertical mixing within the Tasman Sea.

AFAIK the most important source of both vertical heat transport, and pseudo-random unforced variation in vertical heat transport, is vertical mixing driven by mesoscale eddies in the West Pacific.

The motivation for this paper is twofold: first, we validate the model's performance in the Gulf of Mexico by comparing the model fields to past and recent observations, and second, given the good agreement with the observed Gulf of Mexico surface circulation and Loop Current variability, we expand the discussion and analysis of the model circulation to areas that have not been extensively observed / analyzed, such as the vertical structure of the Loop Current and associated eddies, especially the deep circulation below 1500 m.

The corresponding working quasilinear wave equation for the barotropic azonal stream function Ψm ′ of the forced waves with m = 6, 7, and 8 (m waves) with nonzero right - hand side (forcing + eddy friction) yields (34) u˜ ∂ ∂ x (∂ 2Ψm ′ ∂ x2 + ∂ 2Ψm ′ ∂ y2) + β˜ ∂ Ψm ′ ∂ x = 2Ω sin ϕ cos2 ϕT˜u˜ ∂ Tm ′ ∂ x − 2Ω sin ϕcos2 ϕHκu˜ ∂ hor, m ∂ x − (kha2 + kzH2)(∂ 2Ψm ′ ∂ x2 + ∂ 2Ψm ′ ∂ y2), [S3] where x = aλ and y = a ln -LSB-(1 + sin ϕ) / cos ϕ] are the coordinates of the Mercator projection of Earth's sphere, with λ as the longitude, H is the characteristic value of the atmospheric density vertical scale, T˜ is a constant reference temperature at the EBL, Tm ′ is the m component of azonal temperature at this level, u˜ = u ¯ / cos ϕ, κ is the ratio of the zonally averaged module of the geostrophic wind at the top of the PBL to that at the EBL (53), hor, m is the m component of the large - scale orography height, and kh and kz are the horizontal and vertical eddy diffusion coefficients.

Consequently, the vertical velocity in the descent region is a function not only of the net energy input to the atmosphere and the gross moist stability, but also of the energy transport by transient eddies and mean advection.

For example, equatorward - moving weather systems — known as «transient eddies» — fulfill much of the poleward energy export required to balance the net energy input, with the energy transport associated with vertical motion times gross moist stability less important than in the ITCZ.

This paper in Journal of Marine Research has nearly 500 citations and describes vertical eddies in ocean interior using diffusivity as a metric.

Tropical cyclones seem to me to be a very good potential source of forcing «by daily and six - hourly winds and heat fluxes», according to Enhanced vertical mixing within mesoscale eddies due to high frequency winds in the South China Sea [3]:

If eddies are suppressed by a modest but nonnegligible horizontal diffusion and vertical diffusion is kept realistically small, the model thermocline exhibits a familiar two - regime structure with an upper, advectively dominated ventilated thermocline and a lower, advective — diffusive internal thermocline, and together these compose the main thermocline.

When a gyre region is added to the channel, vertical diffusion in the gyre exerts some control on the channel stratification even at higher winds, forcing the mass balance into a mixed regime in which both eddy and diffusive effects are important.

Stronger vertical eddy heat transport in CM2.6 relative to CM2.5 accounts for the significantly smaller temperature drift in CM2.6.
