“…The study just discusses the independent and coupling/synergism effect of the three Poles warming, with rising anthropogenic forcing, ice and snow is reduced, that modulate thermal distribution and atmospheric circulations by surface albedo feedback and hydrological effect of rising evaporation and soil moisture. In addition, El-Nino-Southern Oscillation can drive simultaneous extremes in far distant regions all over the world through teleconnections and global atmospheric variability 22 , which and local land feedback are possible factors that impact on concurrent extremes in 2022, and have been suggested 26 . Additionally, positive sea surface temperature in the tropical western Pacific could excite Rossby waves causing extratropical circulation anomalies and Hadley circulation changes 93 ; the concurrent pattern in summer possible associated with local land forcing effect especially from non-uniform thermal, Eurasian snow cover etc 94 .…”

“…In summer of 2022, this feedback accounted for 42% of extreme heatwaves and droughts in the Yangtze River in China and other regions 22,24,25 . Urban land also experience intensified heatwaves and typhoon floods due to the urban heat island effect, where cities retain more heat than surrounding rural areas 26 . Land processes over Europe and the Tibet Plateau with high diabatic heating can generate anomalies in eddies and transient waves 27 , which can then propagate downstream and affect the occurrence of heatwaves and extreme precipitation events in the downstream regions.…”

Climate warming is causing an increase in the frequency and severity of heatwaves and extreme precipitation events, posing a threat to both socioeconomic stability and human lives. In 2022, five record-breaking heatwaves and floods occurred, it is suggested a new concurrent extreme feature in the study, which is linked to the three Poles warming and ice/snow melting. The independent and synergistic effect of the three Poles warming has led to the poleward movement of westerly jet streams and amplified Rossby waves, as well as the expansion of subtropical highs in both poleward and zonal directions. Consequently, these have intensified heatwaves in the mid-high latitudes and extreme precipitation events in the Asian regions, combined with a southward displacement and weakening of the inter-hemispheric Asian summer monsoon circulations, which are response to poleward of the mid-latitude and subtropical circulations and the hydrothermal effects of the three Poles. This study highlights the significance of three Poles warming in driving amplified concurrent extremes across tropical and extratropical regions, particularly in 2022. These findings provide valuable insights into the role of snow/ice melting and related hydrothermal factors in global climate predictions and disaster prevention efforts.
