Perhaps the most critical section of oceanography within D.S. Lal’s work is the analysis of ocean movements—specifically waves, tides, and currents. Lal approaches these phenomena with a focus on their origins and impacts. In discussing tides, he outlines the gravitational forces exerted by the moon and sun, clearly distinguishing between spring and neap tides. His treatment of ocean currents is particularly noteworthy for its clarity in explaining the concept of "gyres" and the influence of planetary winds (trade winds and westerlies) and the Coriolis force on water circulation. By correlating the atmospheric circulation with oceanic circulation, his work highlights the role of oceans as the "thermal flywheel" of the earth, redistributing heat from the equator to the poles.
