Abstract
- The Soya Current is formed from the transformed subtropical waters of the Tsushima Current, which flows from the Sea of Japan through the La Perouse Strait, spreads along the northern coast of Hokkaido, and enters the Pacific Ocean through the Yekaterina and Kunashir straits. An analysis of satellite data (1993–2019) on sea level, geostrophic current velocity, surface water temperature, and chlorophyll concentration in the southern part of the Sea of Okhotsk, in the zone of the La Perouse Strait (Sea of Japan), and in the southern Kuril region of the Pacific Ocean has been carried out. It has been established that an increase in the sea level difference between the Sea of Japan and the Pacific Ocean leads to the intensification of the Soya current. The main contribution to the change in the level difference between the Pacific Ocean and the Sea of Japan in autumn belongs to anticyclonic eddies and meanders of the Subarctic Front in the Pacific Ocean. An increase (decrease) in the penetration of transformed subtropical waters through the La Perouse Strait is accompanied by an increase (decrease) in the temperature of the surface water layer in the southern part of the Sea of Okhotsk (r = 0.67 in 2000–2019) and a decrease (increase) in the chlorophyll concentration in the Kuril region of the Pacific Ocean (r = –0.70 in 1998–2019) in September–October.
