科普图表：洋流环流图谱

Geographic infographic poster mapping global ocean currents and heat distribution, front-view flat presentation. Layout: a large rectangular world map (Robinson-style projection) centered on the poster, with warm currents drawn as thick coral-orange arrows and cold currents as thick cyan arrows flowing in curved paths across the Pacific, Atlantic and Indian Oceans, each labeled with its name such as the Gulf Stream, Kuroshio, Humboldt, Benguela and Labrador currents. A compact legend in the lower right explains arrow thickness as transport volume in sverdrups, and three small inset panels at the bottom compare sea-surface temperature data with small gradient bars for the Atlantic, Pacific and Indian basins. Color system: land silhouettes in warm sand (#E9D8A6), ocean in deep navy blue (#0F2A43), warm currents in coral (#FF6B57), cold currents in cyan (#3EC1D3). Typography: clean sans-serif map labels, bold title with cartographic style. Background: fine latitude-longitude grid with subtle paper texture. Data feel: oceanography atlas chart with precise scale bars. Lighting: even flat cartographic light, no shadows, crisp vector edges. 4k
