Fig. 11: Steady response of SF anomaly and calculated WAF forced by NPO-like vorticity forcing.
From: Part I observational study on a new mechanism for North Pacific Oscillation influencing the tropics

The steady response of SF anomaly (unit: 105 m2 s−1) and WAF (unit: m2 s−2) was given from the average from 1- to 30-day in a nonlinear stationary wave model. The red and blue dots represent the positive and negative vorticity centers superimposed on the background flow in the model, respectively.
