The Met Office's Met Office
decadal prediction system: DePreSys (DePreSys) is the first in the world.
During 2015
our decadal prediction system was upgraded to use the latest high resolution version of our coupled climate model, consistent with our seasonal forecasts.
To this end, a new paper authored by a team led by Leon Hermanson has just appeared on - line in the journal Geophysical Research Letters that describes a decadal forecasting model developed by the U.K. Met Office and called, rather unimaginatively,
the Decadal Prediction System (DePreSys).
The new research used the Met Office Hadley Centre's
Decadal Prediction System and found that the model was good at predicting summer Sahel rainfall over the forthcoming five years.
Interannual - to -
decadal prediction systems — currently under - development — suggest that slow ocean variations, such as the AMOC, may be predictable.
The decadal predictions system, Met Office decadal prediction system: DePreSys, achieves this by starting predictions from observed atmospheric and oceanic conditions, and including projected emissions of greenhouse gases and variations in natural climate forcings (volcanic and solar activity).
