Antarctica covers a significant portion of the southern hemisphere where surface temperature can be as low as -70°C compared to the surface temperature of 28°C over equatorial region. In this study a possible linkage between anomalies of surface temperature over Antarctica and the performance of monsoon has been examined.
It is observed that the preceding January surface temperature anomaly pattern over Antarctica has an association with the performance of the following monsoon. Drought years are preceded by predominantly warm anomalies over Antarctica and good monsoon years are preceded by equally marked cold anomalies.
