Hurricanes

I'm sure everyone has heard by now: there are two hurricanes
heading toward land this week-end which should impact Louisiana
next Tusday. And of course, the effects will meld in unpredictable ways.

One aspect of the situation which many might not appreciate is
that - because there are currently fewer commercial flights feeding in data
- there is less weather information available for weather models, a situation which
those working in modelling say can make a large difference.

I think of it on the model of the spider vein problem. Yes, one can
get those veins burnt out, but they will return wihth a vengeance, possibly
worse because of the build-up effect. Here, information is missing for a
time, and then suddenly it is there, with stronger and perhaps different outcomes
than anticipated.

Just saying...
