Fig. 7: The lead–lag cross-section of MWAF and SF anomalies averaged over 160°E–120°W.
From: Part I observational study on a new mechanism for North Pacific Oscillation influencing the tropics

The SF (shading; unit: 106 m2 s−1) anomalies are regressed onto the daily NPO index and the meridional WAF (contour; unit: m2 s−2) is calculated based on the SF anomalies.
