US is routinely enbarassed by a more accurate European weather forecast computation. Hurricane Sandy prediction was the glaring example. Part of the Euro prowess is due to better physics. But much of it to a finer model they can compute in real time of a larger computer. Everytime you double the resolution, the computing cost increases 16 times in this 4D computation.
- angry_octet 10y agoYou are implying that the accuracy is mainly due to greater compute. This is simply not true. If the US model could be improved by throwing money for compute at it, that would already have been done. The following paper compares the EU and US ensembles: http://journals.ametsoc.org/doi/full/10.1175/MWR2905.1 http://journals.ametsoc.org/doi/full/10.1175/MWR2905.1
