Vertical movement of the thermocline and horizontal advection appear to be the cause of major changes both between and during the monsoons. During the southwest monsoon the large amount of heat stored in the 0 to 400-m layer during northern spring (up to 31 x 10 super(8) Jm super(-2)) is redistributed with a heat loss of approximately 13 x 10 super(8) Jm super(-2) in the upper 0 to 100-m layer and the gain of a similar amount in the 100 to 400-m layer, caused to a large extent by the dynamic response of these layers to the monsoon wind stress. In late autumn this heat is then advected from the region. PY 1987 SO Oceanologica Acta, Special issue SN 0399-1784 PU Gauthier-Villars ID 37849 ER EF
