Not many of us paid a lot of attention to the weather forecasting systems that the meteorologists use. When we did in the U.S., we were very cynical because the meteorologists just didn’t seem to get it right, almost to the point of the forecasts being a joke. But Superstorm Sandy quickly brought the problem to light: the European system predicted a direct hit on NYC 3 days before the U.S. system did, which was the same day of the storm – a bit too late I would say. WOW! Why?
There is a rather significant difference between the two: the European system has faster computers, more data and better initialization data. This blog post from www.accuweather.com and video from the Today Show explains it all.
Fortunately for the U.S., the Europeans are allowing us to use their data, and have helped us figure out why the U.S. model isn’t performing as well. But it will take time and money to fix. So when planning your next outdoor party, make sure the forecast you consult is from the European model.
