Abstract Since the beginning of the 21st century, Central Europe (CE) has experienced a series of dry summers with substantial socioeconomic and environmental impacts. While the influence of the North Atlantic Ocean is well-established, the role of the Pacific Ocean in modulating CE summer rainfall (CESR) is relatively unknown. Here, we present an evidence by demonstrating the prominent role of the Pacific Meridional Mode (PMM) on the inter-annual variability of CESR. A strong positive phase of PMM is linked to a significant rainfall deficit over CE (10%–15%; p-value 0.05) during the boreal summer season. Further, we demonstrate the implications of this novel teleconnection pattern in improving the predictability of CESR at seasonal timescales—along with the mutually exclusive and independent North Atlantic oscillation. Our study thus reveals the far-reaching influences of the North Pacific Ocean on an improved prediction of the CESR variability, which may aid in improving the adaptation and mitigation strategies.
