Supercomputers Race to Predict Storms 184
pillageplunder writes "CNN has an interesting article on how different supercomputers from around the world are working to predict large storms tracks. The 3 days it takes now has been cut in half. Cool read."

There are a lot of existing, hightly tuned fortan algorithms out there and plenty of scientists to keep the code running.

And much less free on weather.com. Who decided to do that anyway? Charge for a best-guess on a 5-day forecast? I can see that for free on my rabbit ears on the TV.

The most difficult part of the job is predicting hurricane intensity, which is not fully understood. That's why Charley caught everyone off-guard when it abruptly strengthend, and similarly in 2002 there was unexpected relief when Lili (who looked a lot like Ivan) weakened overnight just before it hit land.

One lesson of object oriented is that you should let the language do the work for you. Sometimes this means that you shouldn't use object oriented languages.

Did you ever consider that things happen for a reason? Like balancing global heat loads and adjusting the water vapor cycle?
So instead of having a bunch of light to heavy storms, we'll end up with having ONE BIG MONSTER that we *can't* stop.

Charley swerved just before landfall, Frances stopped dead in the water 60 miles off Florida, and Ivan "bounced" off Jamaica, shifting its path by 500 miles, none of which were predicted. Possibly, none of which are predictable. If you can't warn people where landfall will occur when it takes some non-obvious path, then what's really the point?

If you're waiting for those results at Internet (Latency: 100ms) speeds instead of intra-system speeds (latencyL 1 us) it takes you 100,000 times as long to get your data.
With SETI, all you do is get the data once, compute, and send back the answer.

The boarding-up problem can probably be simplified with rigid mount points and locks on pre-fitted panels. I'm sure a solution can be designed for second story windows where it can be installed and locked in from the inside of the house and still be on the outside to protect the glass. I imagine it could be done such that it only takes a couple minutes per window, five for the largest ones and you can be packing within an hour or two. That might not help for situations where there are just too many people on the road to evacuate in time.
I really can't speak to the other issues raised.
