"The Predictability of the Oceans"
Professor Kirk Bryan, Princeton University, Princeton, NJ
In
tracking climate change due to either natural or man-made factors it is
very important to take into account the role of the oceans. In
polarregions the atmosphere is linked to the oceans by deeply penetrating
convection. While the atmosphere itself is only predictable on the
time-scale of days or weeks, climate variations are in principle
predictable for much longer periods - months or years due to the coupling
between the atmosphere and the relatively stable ocean. Detailed
monitoring of the deep ocean has never been carried out so that data is not
available to make trial forecasts of climate trends at high latitudes. Some
of the most significant climate trends on a multi-decade time-scale are
seen in the northern North Atlantic. To test the predictability of these
trends, sets of numerical calculations have been carried out with a coupled
atmosphere-ocean model. A comparison of the calculations with slightly
different initial conditions in the atmospheric component shows that in the
North Atlantic predictability for the upper ocean is retained for extended
periods. Large scale patterns of sea surface temperature and salinity have
a predictability of up to 5 years, while variations in the ocean
temperature gradients of the North Atlantic have a predictability of decades.
The calculations also suggest how an optimal ocean monitoring
system should be designed.
