• Extraction of cooling-induced current from the satellite sea surface height anomaly in the Japan Sea

抄録

To extract “Cooling-Induced Current (CIC)” component of the Tsushima Warm Current from the satellite sea surface height anomaly (SSHA) data, harmonic analysis of SSHA in spring (February to April) is conducted for 8- and 5-year period, with respect to similarities in the year-to-year variation of Asian Monsoon Index (MOI). In the long-term response of 8-year period, north-eastward flow off shelf edge along the Japanese island is intensified just at the most severe cooling year, which is suggested by the maximum MOI. Such intensified flow, i.e., CIC, gradually migrates offshore during 2 years, and then connects to inflow in the Tsushima/Korean strait via the east coast of Korean peninsula with time lag of about 3 years.
