After marking a trough and two ridges on the 850-hPa map, Cole located an area of CAA, stating, "Cold air advection
you would have down here because you're crossing your wind heights across the temperature lines." He sought additional regions of CAA: "We still have it crossing ...
Equation (4), namely, advection
, can be solved by either a Semi-Lagrangian (Courant et al., 1952) or a first-order upwind scheme.
patterns are nothing to mess around with.
Over East Asia, CNRM-CM5.1 simulated the prevailing wintertime monsoon-related northerly advection
quite well (Figure 6(c)); however, the frequencies of the northwestern and western circulation types were markedly overestimated at the expense of the northeastern circulation type.
For the advection
term, we apply the scheme of either u > 0 or u < 0.
velocities of the fluid phase and of the solid matrix are denoted as u and w, respectively.
of a large number of markers placed near the interface is tracked to capture an interface.
In stochastic representation, marked particles undergo advection
process by wind at a certain speed and at the same time experience random movement simulating turbulent fluctuation.
and diffusion terms are substituted by using the centered difference in space by
A ten percent ([+ or -] 10%) change in each parameter (e.g., source concentrations, initial concentrations, vertical velocity, and angle of advection
) yielded only slight percent differences in the final concentrations of lead.
In the present context, the advection
of a turbulent signal from its measurement point [??]AN to a point [[??].sub.c] downwind is schematized in Figure 12.
We now reconsider the local problem examined in Section 2 while allowing for the effect of advection
. It is suggested in  and  that advection
in a subdiffusive medium can be modeled by adding another fractional derivative term to the basic subdiffusion equation.
