Seasonal prediction skill of ECMWF System 4 and NCEP CFSv2 retrospective forecast for the Northern Hemisphere Winter

The seasonal prediction skill for the Northern Hemisphere winter is assessed using retrospective predictions (1982–2010) from the ECMWF System 4 (Sys4) and National Center for Environmental Prediction (NCEP) CFS version 2 (CFSv2) coupled atmosphere–ocean seasonal climate prediction systems. Sys4 shows a cold bias in the equatorial Pacific but a warm bias is found in the North Pacific and part o...

Basin mode of Indian Ocean sea surface temperature and Northern Hemisphere circumglobal teleconnection

[1] Observational analysis and model experiments show that the sea surface temperature anomaly associated with the Indian Ocean Basin mode (IOBM), which persists from spring to summer, can generate significant circumglobal teleconnection (CGT) in the Northern Hemisphere summer midlatitude atmosphere. A warm IOBM can induce a new atmospheric heating source in the south Asia through a positive fe...
