The merit of the North Sea‐Caspian pattern in explaining climate variability in the <scp>Euro‐Mediterranean</scp> region

Teleconnection patterns are one of the key features to understanding high-frequency natural climate variability. The North Sea-Caspian Pattern (NCP) was identified as a middle tropospheric dipole and its hydroclimatological implications have been substantially restricted Eastern Mediterranean region. Thus, influences NCP in Euro-Mediterranean region were investigated via comparative approach with dominant teleconnections Eurasian synoptic such ridge-trough positioning strength. By using high-resolution ERA5 reanalysis data, cross-correlations between indexes, anticorrelations at 500 hPa composite anomaly maps for seasonally representative months produced understand working mechanism NCP. Comparisons included East Atlantic/Western Russian (EAWR) pattern, rotated principal component analysis (RPCA) variant which utilizes pole-based representation. Analysis revealed that correlated well trough displacement strength Asian trough. Climate anomalies indicated by greater more spatially consistent compared other teleconnections. also showed higher contrasts temperature precipitation than EAWR based on maps. In conclusion, explained variability all seasons linking remote centres action within Eurasia's east west extremes.
