ID-19 :   Hindcast simulation for Arctic impacts on the mid-latitude climate




Hindcast simulation for Arctic impacts on the mid-latitude climate


Hindcast simulation using AGCM (AFES T79L56 version) forced by observational SST and sea ice variation is performed to estimate relative importance of the vertical coupling process and polar-tropics coupling process to the current climate change.

Model Characteristics

AFES4.1 version with T79 horizontal resolution and 56 vertical layers up to 60 km model top.

Computing Environment

Computation resource are provided by JAMSTEC Earth Simulator3.

Abstract (Brief description of the experiment contents (initial conditions, boundary conditions, etc.))
(1) This is the dataset simulated by high-top atmospheric model of which horizontal resolution is 150km-mesh and model-top height is about 60km. The temporally varying climate of the recent three decades (1979-2014) is simulated with historical observation dataset of monthly mean SST and SIC (Hurrel et al., 2008). (2) A 30-member of full historical simulation (like AMIP) is done as control run. Additionally, as the perturbation run (sensitivity run), 30-member runs with fixed SST or fixed SIC interannula variation are performed. (3) Comparison between control and perturbation runs can evaluate contributions of SST/SIC variations on the recent climate change. (4) Total size of this dataset is 68 TB.
