Apparent relationship between Thermal Regime in Antarctic waters and Indian Summer Monsoon

Abstract

Austral winter seasonal and intra-seasonal variabilities of Sub-Tropical Convergence and Antarctic Polar Front are examined using sea surface temperature patterns published in GOSSTCOMP (Global Operational Sea Surface Temperature Computations) charts for the Indian Ocean sector of the Southern Ocean during 2 contrasting years (1977 and 1979) of summer monsoon over India. The results suggest an apparent relationship between the thermal regimes in the Antarctic waters of the Indian Ocean sector and the summer monsoon activity over India, through a link of the Mascarene High southern sub-tropical high pressure zone.
