白令海峡贯通流对楚科奇海、北极和大西洋都很重要。对于高分辨率海洋模型的验证和边界条件，也需要对通流特性进行现实的评估。根据14年的系泊测量，我们构建了温度，盐度和运输的月度气候。楚科奇海水文地理的所有特性（1.31.9至33 psu，1.8至2.3°C和1.4至1.2 Sv）都具有很强的季节性，这意味着北冰洋太平洋沃茨的平衡深度和通风特性具有显著的季节性变化。温度和盐度的年际变化很大。虽然遗漏了一些重要事件，但对当地（模型）风的经验线性拟合产生了合理的水流速度重建，我们使用这种拟合的系数来估计白令海峡通过流的太平洋-北极压力水头强迫的大小。
The Bering Strait through flow is important for the Chukchi Sea and the Arctic and Atlantic oceans. A realistic assessment of through flow properties is also necessary for validation and boundary conditions of high‐resolution ocean models. From 14 years of moored measurements, we construct a monthly climatology of temperature, salinity and transport. The strong seasonality in all properties (∼31.9 to 33 psu, ∼−1.8 to 2.3°C and ∼0.4 to 1.2 Sv) dominates the Chukchi Sea hydrography and implies significant seasonal variability in the equilibrium depth and ventilation properties of Pacific waters in the Arctic Ocean. Interannual variability is large in temperature and salinity. Although missing some significant events, an empirical linear fit to a local (model) wind yields a reasonable reconstruction of the water velocity, and we use the coefficients of this fit to estimate the magnitude of the Pacific‐Arctic pressure‐head forcing of the Bering Strait through flow.
