- Abstract
- The Global/Regional Integrated Model system (GRIMs) is upgraded to version 4.0, with the advancement of the moisture
advection scheme and physics package, focusing on the global model program (GMP) for seasonal simulation and climate
studies. Compared to the original version 3.1, which was frozen in 2013, the new version shows no Gibbs phenomenon in the
moisture and tracer felds by implementing the semi-Lagrangian advection scheme with a better computational efciency at
higher resolution. The performance of the seasonal ensemble simulation (June–August 2017 and December 2016–February
2017) is signifcantly improved by new physics and ancillary data. The advancement is largest in the stratosphere, where
the cold bias is dramatically reduced and the wind bias of the polar jets is alleviated, especially for the winter hemisphere.
Noticeable improvements are also found in tropospheric zonal mean circulation, eddy transport, precipitation, and surface air
temperature. This allows GRIMs version 4.0 to be used not only for long-term climate simulations, but also for subseasonalto-seasonal climate prediction.
