r1i1p1f1

1979.1–2021.11

A reference experiment, the model integration starts from January 1, 1976. All external forcing factors, including greenhouse gases, solar irradiance, ozone and aerosols, are specified as their historical values. And the SST and sea-ice concentration prescribed as the observed values. Export data from January 1, 1979 to December 15, 2021 for analysis.

amip_NMO

r1i1p1f1

1979.1–2021.11

The dynamical perturbation experiment, the height of the topography in the MP and its surrounding regions is modified. The topography above 500 m in the MP and its surrounding regions was set to 500 m.

amip_NS_MO

r1i1p1f1

1979.1–2021.11

The thermal perturbation experiment, which removes the surface sensible heating over the MP and surrounding regions at altitudes above 500 m.
