In light of the rapid Arctic warming and continuous reduction in Sea ice, complex two-way Arctic–midlatitudes connection has become a focal point recent climate research. this paper, we review current understanding interactive influence between midlatitude atmospheric variability ice or thermal conditions on interannual timescales. As sea diminishes, contrast to (cooling) boreal winter (summer), Eurasia North America have experienced anomalously cold (warm) record snowfall (rainfall), forming an opposite oscillation midlatitudes. Both statistical analyses modeling studies demonstrated significant impacts autumn–winter variations cooling, surges, snowfall, as well potential contributions spring–summer warming, heatwaves rainfall, particularly focusing role distinct regional ice. The possible physical processes can be categorized into tropospheric stratospheric pathways, with former encompassing swirling jet stream, horizontally propagated Rossby waves, transient eddy–mean flow interaction, latter manifested anomalous vertical propagation quasi-stationary planetary waves associated downward control anomalies. turn, prevailing patterns midlatitudes also contribute condition anomalies by meridional energy transport. fluctuates over time is influenced multiple factors (e.g., melting climatological different locations magnitudes anomalies, internal variability, other external forcings), undoubtedly increasing difficulty mechanism uncertainty surrounding predictions weather climate. conclusion, provide succinct summary offer suggestions for future

In recent decades, Northeast China (NEC) has witnessed a substantial 20% rise in the occurrence of intense winter snowfall, resulting notable increase overall snowfall accumulation. Using Empirical Orthogonal Function (EOF) analysis, this study identifies dominant interdecadal variation extreme with turning point around 2000. The analysis uncovers abnormal atmospheric circulations linked to positive phase like-Scandinavian pattern and anomalous North Pacific anticyclone, providing favorable conditions for cold air outbreak water vapor enhancement snowfall. exhibits strong correlation sea ice loss Baffin Bay, Greenland Sea, Barents-Kara Sea (BGBK). This is primarily sustained by feedback mechanism stemming from sea-ice-atmosphere interactions. Specifically, leads increased over BGBK region, promoting through enhanced clear-sky downward long-wave radiation (CDLW) surface turbulent heat flux. Conversely, temperature anomaly prevails negative Interdecadal Oscillation (IPO), triggering an anticyclone East Asia, contributing observed NEC. Furthermore, demonstrates modulating relationship between associated IPO, achieved Rossby wave trains, which were verified numerical experiments using general circulation model. These results underscore joint impact variability Arctic IPO on decadal

Abstract The Northeast Pacific Ocean (NEP) is one of the hotspots marine heatwaves (MHWs) occurring in global ocean. causes MHWs this region have been widely investigated, but physical processes underlying and regional climate variability remain under debate. By analyzing interannual large-scale high-latitude atmospheric dynamics oceanic conditions over NEP, we show that winter-spring sea surface temperature (SST) anomalies are strongly correlated with blocking events Alaska. occurrence weaker westerly wind subarctic NEP during period blocking, accompanies a shallower vertical mixed layer, less southward horizontal Ekman transport, higher SST upper NEP. These findings establish linkage between reveal mechanisms connection, providing new insight into possible MHW
