The ECE is an anticyclonic eddy, barotropically structured and centered at 33.64"S and 176.2TE, with warm and salinous- cored subsurface water. The radius of the eddy is of the order O (110 km) and the maximum circumferential velocity is O (40cms-1); as a result, the relative vorticity is estimated to be O (7x 10-6s-1). Due to the existence of the ECE, the mixed layer north of New Zealand becomes deeper, reaching a depth of 300 m in the austral winter. The ECE plays an important role in the formation and distribution of the Subtropical Mode Water (STMW) over a considerable area in the South Pacific.展开更多
