章节大纲

    • The main objective of the lectures in "Seawater travels, Heat also travels" is to understand the formation mechanism of the subtropical gyre.

      The subtropical gyre is a giant clockwise vortex in the North Pacific spanning Japan to the United States, and is driven by the westerlies and trade winds. The Coriolis force (the apparent force generated by the rotation of the Earth) plays an important role in driving the vortex. The subtropical gyre redistributes heat from the oceans through solar radiation by transporting high-temperature water from low latitudes to mid-latitudes on the western side (Kuroshio) and low-temperature water from mid-latitudes to low latitudes on the eastern side.

      The goal is to help students understand the essence of these phenomena by explaining these mechanisms in figures and words, without using mathematical formulas.
