Antarctica sea-ice and monsoon variability
This study statistically evaluates the relationship between satellite derived Antarctic sea ice extent and Indian summer monsoon variability over the various homogeneous regions of India. Analysis is carried out for 22 years (1979-2000). From the analysis it is observed that preceding winter (Decemb...

| Summary: | This study statistically evaluates the relationship between satellite derived Antarctic sea ice extent and Indian summer monsoon variability over the various homogeneous regions of India. Analysis is carried out for 22 years (1979-2000). From the analysis it is observed that preceding winter (December-January-February) sea-ice anomaly has an inverse association with the performance of the following monsoon. It is observed that deficient monsoon years are preceded by more than normal sea-ice extent, and in excess or normal monsoon years the sea ice extent is less than the normal. The relationship is statistically significant at 1 level. From the study it is found that southern peninsular India does not show a significant relationship. |
