Enhanced Seasonal Prediction Skill of the Western Pacific Subtropical High Over the Past Century

Abstract The Western Pacific Subtropical High (WPSH) is crucial in shaping summer climate of East Asia. However, existing studies on WPSH seasonal prediction have primarily focused on the recent 20–30 years, limiting our ability to assess decadal variations in prediction skill. Here, based on CSF‐20C seasonal hindcast (1901–2010), we find the prediction skill of WPSH improved post‐1960s due to inc…
