Met Office to build £97m supercomputer
Funding has been confirmed for a £97m supercomputer to improve the Met Office's weather forecasting and climate modeling.
The facility will work 13 times faster than the current system, enabling detailed, UK-wide forecast models with a resolution of 1.5km to be run every single hour, rather than every three.
It will be built in Exeter during 2015 and become operational next September.
The Met Office said it would deliver a "step change" in forecast accuracy.
"It will allow us to add more precision, more detail, more accuracy to our forecasts on all time scales for tomorrow, for the next day, next week, next month and even the next century," said Met Office chief executive Rob Varley.
This will be fine for short-term forecasting. The models for this have been getting better and better. Long range forecasts? Not so much. The climate scientists are still in the tank for global warming and their models still predict temperature increase despite the 19 years of stasis and cooling. These models do not hind-cast at all.
