Abstract

Abstract

The simulation of an ocean general circulation model for the earth simulator (OFES) is transformed to an isopycnal coordinate to investigate the spatial structure and seasonal variability of the Mindanao Undercurrent (MUC). The results show that (1) potential density surfaces, σ_θ=26.5 and σ_θ=27.5, can be chosen to encompass theMUC layer. Southern Pacific tropicalwater (SPTW), Antarctic IntermediateWater (AAIW) and high potential density water (HPDW) constitute the MUC. (2) Climatologically, the MUC exists in the formof dual-core. In somemonths, the dual-core structure changes to a single-core structure. (3) Choosing section at 8°N for calculating the transport of the MUC transport is reliable. Potential density constraint provides a good method for calculating the transport of the MUC. (4) The annual mean transport of the MUC is 8.34×10⁶ m³/s and varies considerably with seasons: stronger in late spring and weaker in winter.
