Quantification of the transport of chemical constituents from the polar vortex to midlatitudes in the lower stratosphere using the high-resolution advection model MIMOSA and effective diffusivity (2002, methodology): “Using the definition of the effective diffusivity, the diffusion equation for the tracer distribution is expressed [Haynes and Shuckburgh, 2000a]: @Cðfe; tÞ @t ¼ 1 r2cosðfeÞ @ @fe keff ðfe; tÞcosðfeÞ @Cðfe; tÞ @fe : ð4Þ [18] The effective diffusivity diagnostic has been applied by Haynes and…”
Relation between kinematic boundaries, stirring, and barriers for the Antarctic polar vortex (2002, background): “It can be demonstrated for advection diffusion equation that contour length is a lower bound of the effective length (Haynes and Shuckburgh 2000) but it has been shown that in practice the two quantities stay always very close (E. Shuckburgh 2001, personal communication).”
Estimating Eddy Stresses by Fitting Dynamics to Observations Using a Residual-Mean Ocean Circulation Model and Its Adjoint (2005, background): “This is reminiscent of the pattern of eddy diffusivities observed in the atmosphere: effective diffusivities peak on the equatorial flank (tropospheric side) of the middle-latitude jet stream (see Haynes and Shuckburgh 2000).”
Lagrangian Coherent Structures (2015, background): “…4), finite-size Lyapunov exponents (FSLEs; see Aurell et al. 1997, Joseph & Legras 2002, d’Ovidio et al. 2004), effective diffusivity (Nakamura 1996, Haynes & Shuckburgh 2000, Shuckburgh & Haynes 2003), stretching in particle-fixed frames (Tabor & Klapper 1994, Lapeyre et al. 1999, Haller & Iacono…”
Jets and Topography: Jet Transitions and the Impact on Transport in the Antarctic Circumpolar Current (2012, background): “For flows in a chaotic advection regime, it is the largescale coarse-resolution velocity field that is the most important for tracer and particle advection (Haynes and Shuckburgh 2000; Marshall et al. 2006).”
Suppression of Eddy Diffusivity across Jets in the Southern Ocean (2010, methodology): “The approach has been used extensively in atmospheric studies (e.g., Haynes and Shuckburgh 2000a,b) and more recently in oceanographic studies (e.g., Marshall et al. 2006).”
Multiple Jets as PV Staircases: The Phillips Effect and the Resilience of Eddy-Transport Barriers (2008, background): “That is, the wavelike regions with their associated eastward jets act as “eddy-transport barriers” (e.g., Juckes and McIntyre 1987; Nakamura 1996; Haynes and Shuckburgh 2000; Marshall et al. 2006; Haynes et al. 2007).”
Estimates and Implications of Surface Eddy Diffusivity in the Southern Ocean Derived from Tracer Transport (2006, background): “If | q| ! const on dl, then L2eq L 2, as discussed in Haynes and Shuckburgh (2000a).”
Enhancement of Mesoscale Eddy Stirring at Steering Levels in the Southern Ocean (2010, methodology): “Cross sections can be built by stacking the results from many such slices, as described for example in Nakamura and Ma (1997) and Haynes and Shuckburgh (2000a), who used isentropic surfaces in the atmosphere, or Cerovecki et al. (2009), who employed the same neutral-surfaceprojection technique…”
