In general, the salinity maxima (not just in the Atlantic but also in the Pacific) occur at around 20 degrees latitude north and south, which corresponds to the latitudes of the world's great deserts, where evaporation also exceeds precipitation.

一般来说，最大盐度（不仅在大西洋，而且在太平洋）出现在南北纬 20 度左右，这与世界大沙漠的纬度相对应，那里的蒸发量也超过了降水量。
