Евразии: прогнозы на период с конца лета 2026 года по зиму 2026-2027 г

Climate Dynamics and Systemic Vulnerability in Eurasia: Projections for Late Summer 2026 to Winter 2026-2027 Abstract The global climate system has entered a period of unprecedented instability, characterized by the convergence of anomalous oceanic, atmospheric, and stratospheric factors. As the Northern Hemisphere transitions from late summer 2026 to winter 2026-2027, observational data and ensemble modeling indicate the rapid emergence of a Super El Niño event, exacerbated by a historically warm global ocean base. This transition occurs against the backdrop of a shift in the Quasi-Biennial Oscillation (QBO) to a strong westerly phase and the Atlantic Meridional Overturning Circulation (AMOC), which is showing increasingly pronounced signs of velocity-driven destabilization. The atmospheric response to these interacting climate forcing mechanisms is projected to significantly alter traditional weather patterns in Europe, the Russian Federation, the South Caucasus, and the Mediterranean Basin. A warmer-than-average European winter threatens to decouple biological cycles from the calendar year, severely impacting the vernalization of winter crops and agricultural yields. Conversely, localized and sudden disruptions of the stratospheric polar vortex pose a persistent threat of severe frosts—reminiscent of the "Beast from the East"—that will immediately test the resilience of Europe's energy security architecture after Russia's withdrawal, especially given historically low levels of gas storage. At the same time, extreme sea surface temperatures in the Mediterranean are preparing the region for intense tropical cyclones in late summer ("medicanes"), while the Kura-Aras River basin in the South Caucasus faces an existential hydroecological crisis caused by severe drought and systemic infrastructure failure. This report presents a comprehensive interdisciplinary analysis of meteorological drivers, regional climate trajectories, and cascading socioeconomic risks expected in the 2026-2027 season. Global Climatological Drivers: Macrofactors for the 2026-2027 Season The seasonal forecast for 2026-2027 is based on complex interconnections between warming in the equatorial Pacific, stratospheric wind changes, and the thermohaline circulation in the North Atlantic. The convergence of these vast macro-factors creates a high-energy atmospheric baseline that will shape global weather patterns. Rapid onset and strengthening of the 2026 super El Niño Following the rapid end of the multi-year La Niña phase, a profound thermal shift occurred in the equatorial Pacific. Oceanographic monitoring by the TAO/TRITON buoy system revealed a powerful deep-water Kelvin wave propagating eastward across the Pacific. These underwater Kelvin waves are the primary mechanism for transporting massive amounts of ocean heat, driven by westerly winds that push warmer surface waters toward the coast of South America, where they eventually emerge at the surface.
