| Abstract: |
Objective: To test the model simulation ability in reproducing:
i) the spatial structure and temporal variability of the leading modes of low-frequency variability of the circulation in the SH, and,
ii) the relative contributions of the leading modes to the explained variance of regional circulation, and precipitation in South America.
Simulations: Pre-industrial control, 20C3M, SRES A2, SRES A1B
Model Data required:
- Global monthly means at 850, 500, and 200 hPa of the following variables: geopotential height (zg850, zg500, zg200), eastward wind (ua850, ua500, ua250), northward wind (va850, va500, va250) and specific humidity (hu850, hus500, hus250).
- Global monthly means of sea surface temperature, precipitation flux, and sea level pressure: ts, pr and psl.
