The ECCO global WOCE synthesis is used to analyze ocean volume, heat |
| 6 |
|
|
and freshwater transports. Time-mean horizontal transports, estimated |
| 7 |
|
|
from this fully time-dependent constrained circulation, are now generally |
| 8 |
|
|
consistent with the time-independent inverse estimates from box inversions, |
| 9 |
|
|
with especially good agrement in the southern hemisphere. |

|
The estimated mean circulation around Australia involves a net volume |
| 12 |
|
|
transport of 11 Sv through the Indonesian Throughflow and the Mozambique |
| 13 |
|
|
Channel. This flow regime exists on all time scales longer than one |
| 14 |
|
|
month---rendering the variability in the South Pacific strongly coupled |
| 15 |
|
|
to that in the Indian Ocean. |

|
Dynamically consistent variations in the model show temporal variability |
| 18 |
|
|
of oceanic heat transports, heat storage and atmospheric exchanges that |
| 19 |
|
|
are complex and with a strong dependence upon location, depth, and |
| 20 |
|
|
time-scale. One can now study the dynamics of both the mean and time |
| 21 |
|
|
variability from the model with the reassurance that it is consistent |
| 22 |
|
|
with the great bulk of the WOCE observations. |
