Altimeter sea surface height observations in the Leeuwin Current,
Western Australia, and East Auckland Current, New Zealand, have been
projected to subsurface temperature and salinity anomalies using
statistical methods. These analyses were assimilated in ROMS using
the intermittent optimal interpolation scheme of Dombrowsky and De Mey
(JGR, 1992) to obtain hindcasts of mesoscale variability in these two
boundary current regions. Qualitative features of variability, and
quantitative estimates of hindcast skill, are presented.
