temperature at the Japan Sea surface

Daily fields of satellite and simulated temperature (SST) at the Japan Sea surface were decomposed
to empirical orthogonal functions (EOF). SST from Japan Meteorological Agency binned into 0.25°
boxes and spanning from October 1993 to November 2006 were analyzed. Numerical simulations were
performed using an oceanic model forced by wind reproducing conditions of (1) typical monsoon, (2)
strong summer monsoon, and (3) no-monsoon. Three leading EOF modes of SST anomalies simulated
under the forcing of typical monsoon wind correspond to those derived from the satellite SST. It is
shown that SST anomalies can be related to dynamic processes in the Japan Sea induced by variability of
wind stress curl.
Keywords: sea surface temperature, empirical orthogonal functions, heat advection, oceanic model, semiannual time-scale, subarctic front, wind stress curl
