Just a quick note: I happened on this post on “Weather Underground” which gives some excellent perspective on models, and appears to be the first in a series. If the rest are as good as this, reading the entire series will be time well spent. Look for the entry titled “Models(1) Assumptions:”

    Ricky Rood’s series on climate change has been running for some time, and he’s posted a lot of excellent material - designed, in the main, to educate the commenters at WU on the subject. It’s a good series to add to your RSS feeds…

    A really, really good, non technical source for info on climate models is

    Step by step introduction into climate modelling, and some of the basic physics, chemistry and assumptions.

    I would also recommend the following introduction to atmospheric circulation models, put out by the European Centre for Medium Range Weather Forecasting (ECMWF):

    It’s a good, non-technical explaination of a _weather_ model . These are very different from _climate models_ (and in my opinion, much more interesting) but have enough similaities in the measurement and modelling of the atmosphere to give you an idea of how these models work.

    For those that are interested, here’s the technical documentation:

    Weather models much more interesting? Yes, the luckless inhabitants of the town of Gloucester in the UK might agree on that. After having relaxed with an early spring medium range forecast from the UK Met Office of a fairly dry hot summer, but with some heavy rain well to the north of them, they woke up last summer to find themselves both cold and a few meters under water and the army frantically trying to save their power station from flooding.

    It must have been an educational experience for everyone on the difficulties of doing medium range weather forecasts, hopefully including the weather forecasters.

    If they turned their televisions off after hearing the medium-range forecasts, they got what hey deserved.
