“…Kurasawa et al (1983) described the variation of ocean heat content and surface heat flux at station Tango at various time scales, based on the JMA's observational data, and evaluated the contribution of surface heat flux and oceanic heat convergence to the variation of heat content in the surface layer. Another study comprises the surface mooring observations located in the vicinity of station Tango during the Ocean Mixed Layer Experiment (OMLET) in 1988-1991. Otobe et al (2003 presented the result of the temperature observations and examined the heat balance based on the OMLET mooring data, describing variation of ocean heat convergence in relation to the fluctuation of the Kuroshio axis.…”
