1000-member ensemble simulation output from NIES Chemistry-Climate Models for investigating Southern Hemisphere Stratospheric response to the sea surface temperature
Click Here to Download
The response of the southern hemisphere stratosphere to the ocean-surface conditions in 2002 and 2019, when exceptional sudden stratospheric warming (SSW) events occurred, were examined through 1010-year continuous Chemistry-Climate Model (CCM) runs. In comparison, the experiments with 2000 climate conditions and 2019 atmospheric nudging were performed. The datasets include zonal wind, temperature, and total ozone outputs with calculated EP flux data in these simulations. Data from the last 1000 years of the 1010-year calculation are stored as a 1000-member ensemble.

Calculation method
|
Chemistry-climate model (CCSRNIES-MIROC32) is a spectral model with a resolution of T42 (2.8° × 2.8°) in horizontally and 1-3 km in vertically with 34 eta Levels (top level 0.01hPa). The reference experiment (CNTL) was conducted under the year 2000 climate conditions, with the surface concentrations of greenhouse gases (GHGs) and ozone-depleting substances (ODSs) being fixed at the 2000 mean values. The sea surface temperatures (SST) and sea-ice distributions were prescribed by the calendar-month 1991–2020 climatology, calculated from the monthly mean NOAA OI SST V2. The reference experiment with the calendar-month 1995–2004 climatology (CNTL_1995-2004) was also conducted. In the 2002 experiment (E2002), the monthly mean SST and sea ice of 2002 were prescribed in every year; in the 2019 experiment (E2019), the SST and sea ice data were those of 2019. E2019Trop was conducted by nudging the zonal and meridional winds between 300 hPa and 1000hPa of the Japanese 55-year Reanalysis (JRA-55) dataset.
