Weather reports are to be produced from one main location following advances in communications and hi-tech forecasting techniques, the Met Office has said.
Most Met Office services will be produced in Exeter
Forecast production will be moved from centres in Birmingham, London, Belfast, Cardiff and Manchester, to a new building in Exeter, Devon.
The new Met Office base in Aberdeen will maintain a key role in providing services to the marine community.
The service said it would be able to deliver improved services.
Forecast advisers will still be based at Aberdeen, Manchester, London and Cardiff.
Defence Minister Don Touhig said: "Aberdeen will continue to provide services to the UK commercial marine community, in particular the oil and gas industry, retaining their forecast production facility."
Met Office chief executive Mark Hutchinson said: "Investment in the new Exeter headquarters and associated technology - such as massive supercomputing power - has considerably improved our forecasting capability in recent years.
"This unique capability, combined with huge advances in telecommunications, means that we are able to produce accurate forecasts for any part of the UK from a central location.
"There will continue to be a regional presence, across the UK, provided by account managers and, where required, forecaster advisers."
