Figure 2: Mean-square seven-day range prediction error for temperature at two different depths over the first three months of 1998 for several simulations initialized with the January 1, 1993 conditions: free run (solid line), assimilation of altimetry and XBT profiles (simulated) using one basin-wide EOF (dash-dot line), assimilation using regional EOFs (dotted line). (a) 120 m; (b) 280 m. Unit: °C.
