Sentences with word «diffusivity»

Using an effective ocean diffusivity of 0.65 cm ^ 2 / s (which is the central estimate derived in the Forest 06 study), the surface temperature response to a step forcing increase reaches about 90 % of its ultimate level within 25 years, if I've got everythng right.

Ocean parameters: horizontal and vertical ocean diffusivity k H = 200 — 5,000 -LCB- 2000 -RCB- m2 / s, k V = 0.1 — 1.0 × 10 − 4 -LCB- 0.3 × 10 − 4 -RCB- m2 / s at top, 1.1 — 2.0 × 10 − 4 -LCB- 1.3 × 10 − 4 -RCB- m2 / s at ocean bottom (vertical profile after Bryan Lewis).

Tan, Z., C. M. Kaul, K. G. Pressel, Y. Cohen, T. Schneider, and J. Teixeira, 2018: An extended eddy - diffusivity mass - flux scheme for unified representation of subgrid - scale turbulence and convection.

Part II: Vertical diffusivities of momentum, heat, salt, mass, and passive scalars.

In other words, we obtained a site specific, tortuosity - depth relationship by adjusting diffusivity until the model reproduced the observed CO2 firn - air profile when driven by the independently derived atmospheric CO2 history (see Fig.

We find that over a wide range of values of diapycnal diffusivity and Southern Ocean winds, and with a variety of changes in surface boundary conditions, the spatial patterns of ocean temperature anomaly are nearly always determined as much or more by the existing heat reservoir redistribution than by the nearly passive uptake of temperature due to changes in the surface boundary conditions.

The researchers were puzzled by a nonlinear drop in surface water diffusivity — as measured by the Overhauser dynamic nuclear polarization apparatus in the Han lab — as the chemical composition of the silica surface moved from hydrophobic to hydrophilic.

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

It is also an attractive anode material for lithium - ion batteries because it has a large theoretical charge - discharge capacity compared to graphite and high lithium ion diffusivity at room temperature compared to silicon.

We can go a long way toward solving both problems if the disk gas surrounding planets has no intrinsic diffusivity («viscosity»).

LH GM metrics (i.e., percent spared cortical tissue) and bilateral WM scalars (i.e., fractional anisotropy [FA], mean diffusivity [MD]-RRB- were obtained from cortical and subcortical masks in each ROI.

The experiments confirmed results from earlier more idealized studies, particularly the importance of reduced wave dissipation activity, in which the mid-latitude decrease of effective diffusivity appears to be dominant.

The results highlight the capability of LIGHT to compute the horizontal and vertical structure of diffusivity within the high performance computing Model for Prediction Across Scales Ocean framework.

In fact that's a large difference in effecitive diffusivity.

The third equation in our simple carbon - cycle model, which relates to C1, accounts for advection of CO2 into the thermocline and land — biosphere; b2 represents an adjustable diffusivity, while b1 + b3 + b4 = 0.85 is the fraction of CO2 that would remain in the atmosphere within a year of a pulse injection [11].
