Abstract

In August 2022, Pakistan experienced unprecedented monsoon rains, leading to devastating floods. This study elucidates the dominant influences of tropical and extratropical intraseasonal oscillations on this extreme rainfall event. Scale-decomposed moisture budget analysis revealed that intense rainfall was driven by enhanced vertical moisture transport, primarily from interactions between intraseasonal circulation anomalies and the background moisture field. Subseasonal-to-seasonal prediction models highlighted the critical role of tropical intraseasonal modes in predicting this extreme event.
