拉普捷夫和东西伯利亚海陆架夏季表层盐度的年际变化来自20世纪50年代至21世纪初的历史记录，归因于大气涡度变化。在气旋制度（正涡度）的向东转移的拉普捷夫海河水的结果在一个负的盐度异常的东部的勒拿河三角洲和更远的东西伯利亚海，和一个正的异常勒拿河三角洲的北部。反气旋（负）涡度导致负盐度异常从勒拿河三角洲向北，由于淡水平流向北，相应的盐度向东增加。
High interannual variability of summer surface salinity over the Laptev and East Siberian Sea shelves derived from historical records of the 1950s–2000s is attributed to atmospheric vorticity variations. In the cyclonic regime (positive vorticity) the eastward diversion of the Laptev Sea riverine water results in a negative salinity anomaly to the east of the Lena Delta and farther to the East Siberian Sea, and a positive anomaly to the north of the Lena Delta. Anticyclonic (negative) vorticity results in negative salinity anomalies northward from the Lena Delta due to freshwater advection toward the north, and a corresponding salinity increase eastward.
