mechanisms by which eddies are created. One is through the instability of large-scale currents such as the Gulf Stream, the North Atlantic Current, the Azores Current, and the Agulhas Current. The coherent eddies produced by these jets transport fluid with anomalous temperature and salinity over large distances giving a significant contribution to the oceans thermohaline circulation ( Wunsch 1984 ). The instability of these jets has often been modeled using quasigeostrophy (QG) since they typically have

filamentary nature of these fronts and their relationship with meandering velocity jets has been highlighted ( Hughes and Ash 2001 ; Sokolov and Rintoul 2007b ). Later work by Sallée et al. (2008) , Sokolov and Rintoul (2009) , and Langlais et al. (2011) have indicated that the surface signature of fronts are related to subsurface hydrographic properties, which is consistent with the equivalent barotropic structure of the ACC. The strength of the fronts, as defined by the amplitude of property

eastward volume and heat transport of the western boundary currents (e.g., Wijffels et al. 1998 ) and their variability has been recognized in recent years to be crucial in understanding the low-frequency midlatitude oceanic changes ( Spall 1996 ; Qiu and Miao 2000 ; Schmeits and Dijkstra 2001 ; Dewar 2003 ; Hogg et al. 2005 ; Pierini 2006 ; Berloff et al. 2007 ; among others). In the North Atlantic Ocean, various observations also reveal the presence of a RG north of the Gulf Stream jet between
