Abstract
Transport variations with periods of 3 ∼ 5 days have been measured in the Korea (Tsushima) Strait by cross-strait cable voltage
fluctuations and by direct, long-term measurement. Here we show that these variations can be explained in part by large-scale
atmospheric pressure fluctuations over the East (Japan) Sea. First, using basin-wide averages of atmospheric pressure and
sea surface height we show that sea surface height in the East Sea is not in isostatic equilibrium with atmospheric pressure,
and that the imbalance is correlated with transport fluctuations. Second, we use a simple model to estimate the relationship
between these quantities. The model displays a Helmholtz-like resonance in the observed range of periods and is in reasonable
agreement with the observed transport variations.
