초록
Three HF ocean radar stations were installed at the Soya Strait in the Sea of Okhotsk in order to monitor the Soya Warm Current. Frequency of the HF radar is 13.9 MHz, and range and azimuth resolutions are 3 km and 5 deg., respectively. Surface current velocity observed by the radars shows good agreement with drifting buoy and shipboard ADCP observations. The velocity of Soya Warm Current reaches its maximum, which is about 1 m/s, in summer, and becomes weak in winter. The surface transport across the strait shows a significant correlation with the sea level difference along the strait.
