ClimatePrediction 3.0.00
下載
A few of us are looking to put together a new
optional experiment to look at how climate might change as CO2 changes in
the event of a decrease in the strength of the thermohaline circulation
(predicted by many but not all climate models). This is kind of topical
right now both in terms of various bids we have in place to look at rapid
climate change and because of recent mdeia attention (and the forthcoming
film The Day After Tomorrow). We'd like to invite volunteers from the
board who are currently in phase 3 and who are up for a challenge (which
might well fail) to download an upgrade package that will add a fourth,
THC slowdown phase to the experiment.
The fourth phase will repeat the third phase of the current experiment,
only with different ocean surface properties. In the fourth phase we'll
use patterns of North Atlantic sea surface temperature derived from some
thermohaline circulation (THC) slowdown experiments to test the
atmospheric responses to both a doubling of CO2 and a change in the
strength of the Atlantic over-turning circulation.
This isn't a prediction of how likely a THC slowdown is. This is a way of
looking at how the atmosphere is likely to respond given such a slowdown.
At this stage we're still trying to evaluate the feasibility of making
this a proper part of the experiment. This is very much a test - but we'd
like to get some idea of how viable the experiment is likely to be. And a
few people here on the board suggested we try to tie in with the upcoming
film, so here's an opportunity to run a model under THC slowdown
conditions. We can't promise tidal waves and glaciers over New York,
though...
I must stress that this is still under testing and might contain some bugs.
You're also advised to make a backup before upgrading.
If you'd rather not take the risk, then its probably safer to stick to the stable release.
