The Kuroshio is a very well-known ocean current that flows along Japan's southern coast. Occasionally, the current deviates from its usual course in a phenomenon known as the "Kuroshio large meander." This meander started again in September 2017, the first time in 12 years, and is currently ongoing. Research has revealed how this meander has contributed to a rich oceanic ecosystem as well as an increase in snowfall around Tokyo. In this episode, we'll look at the latest research about the mechanism of the large meander and its significant impact on fishing, shipping, and weather.
