Weather models, a visual comparison

Posted to Statistical Visualization  |  Tags:  |  Nathan Yau

Forecast, one of the best if not the best quick-look weather sites, uses various weather models to predict temperature, wind, humidity, and pressure. Whereas the main result is an estimated map view along with highs and lows for the week, Forecast Lines shows you the the weather models that drive the site.

Forecast works by statistically aggregating a number of different weather models into a single forecast. Because I can peek under the hood, I was able to take a look at all the raw models and see how many dipped below freezing. I saw that none of them did, which gave me confidence that my plants would be okay.

Today we’re launching a new weather app that lets everyone “peek under the hood.” We’re calling it Forecast Lines.

And like the main Forecast site, it works fine and dandy on your iPad or mobile device.
