Mixing from meridional circulation

FIGURE 20 Schematic of the mechanisms that affect ozone distribution in the stratosphere. The mean meridional circulation is denoted by the heavy arrows it transports ozone poleward and downward from the source region in the tropical middle stratosphere. The circulation also carried into the stratosphere compounds of anthropogenic origin that contribute to ozone loss. The effect of quasihorizontal mixing by breaking planetary waves is denoted by the dashed lines with arrows. [From R. R. Garcia (1994). Phys. World 7, 49-55.]... [Pg.219]

In the open ocean, the major advective water motion is associated with the surfece-water geostrophic currents and meridional overturning circulation. These flow paths are shown in Figures 4.4b and 4.6. Advection is much fester than molecular diffusion and turbulence. This enables water masses to retain their original temperatures and salinities as they are advected away from their sites of formation. Slow turbulent mixing with adjacent water masses eventually alters this temperatme and salinity signal beyond... [Pg.84]

Figure 3.25. Schematic representation of the wave-driven transport circulation (solid lines with arrows) in the winter stratosphere. The shaded area represents the surf zone where meridional mixing associated with wavebreaking is taking place. Light dashed lines represent isentropes. The heavy dashed line shows a constant mixing ratio surface of a long-lived tracer. The dotted line represents the tropopause. Adapted from Holton and Alexander (2000). Figure 3.25.

Figure 3.27. Schematic representation of the global diffuser model (upper panel) and tropical pipe model (lower panel). Gray arrows denote meridional transport by the transformed Eulerian mean circulation while the heavy solid arrows show quasi-horizontal mixing by large scale waves. The vertical lines in the lower panel represent dynamical barriers against meridional transport in the tropics. From Plumb and Ko (1992). Figure 3.27.
