Table 1 Correlation coefficients of the first and second EOF mode time coefficients of vertical velocity w, vertical volume transport (\(V_z\)), and vertical temperature transport (\(F_z\)) at 100 m depth with respect to Niño 3.4 index; and those of \(V_z\), \(F_z\), the temperature tendency (\({\partial } T_{w}/{\partial } t\)) and temperature variation (\(T^{\prime }_{w}\)) in the top 100 m layer in Region A with respect to PDO index
