Summary: This study investigates the future changes of extratropical cyclones (ETCs) over East Asia using models from CMIP5. The results suggest that under a warming climate, there may be a reduction in the frequency of ETCs on the leeward side of the Tibetan Plateau, East China Sea, and western North Pacific. Additionally, there is a hint of weakening in ETC intensity over the North Pacific. These changes are largely influenced by enhanced static stability and reduced vertical wind shear.

Summary: This is the first study to quantitatively evaluate the changes in uncertainty components of future temperature and precipitation projections using multiple regional climate models over East Asia. The study found that internal variability and model uncertainty were the main factors affecting near-term temperature projections, while scenario uncertainty became the dominant factor after mid-term projections. Precipitation showed similar uncertainty factors as temperature in the near-term projections, but differed significantly in terms of the contribution of internal variability to total variance. This study is significant as it provides new possibilities for considering climate uncertainties in the development of climate change policies at the regional scale.

Summary: This study investigates the impact of future changes in El Nino events on East Asian summer rainfall. The results suggest that the intensity of El Nino events and the phase of the Pacific Decadal Oscillation can influence the changes in East Asian summer rainfall. Changes in El Nino-driven wind circulation anomalies are found to be the main factor influencing the changes in East Asian summer rainfall.

Summary: This study aimed to investigate the habitat distribution of the important tree species Sapindus and its response to climate change in Asia. The study found that precipitation played a key role in shaping the distribution of Sapindus habitats. Under future climate change scenarios, the habitats of Sapindus were predicted to expand or contract depending on the species and location. Additionally, different species of Sapindus exhibited distinct ecological habits in East and Southeast Asia.

Summary: Through simulating an ensemble of global models, we found that the intensity of South Asian monsoon LPS has decreased, while weaker LPS showed no significant trend. In the future, LPS will shift from ocean to land, and precipitation will increase, leading to an increase in seasonal mean and extreme precipitation over central India.

Summary: This study evaluates the changes in extreme precipitation in the spring and Mei-yu seasons under global warming. The results show that extreme precipitation in the spring exhibits larger enhancements and a tendency of northward extension, while extreme precipitation in the Mei-yu season strengthens and becomes more frequent. These findings suggest that water resource management will face greater challenges in a warmer climate.

Summary: This study aims to develop a nonstationary modeling approach to generate future regional IDF curves by incorporating the trend in rainfall over the Asian Monsoon Region (AMR). The results show that the change in extreme rainfall intensity for the future climate is mainly dependent on the extreme precipitation zones of the region for both near-future and far-future scenarios.

Summary: This study aims to investigate the role of synoptic weather systems in influencing aerosol variation over East Asia under future changes in atmospheric dynamics. The results show that the major synoptic weather patterns of each season are among the dominant factors affecting aerosol optical depth (AOD) variations. The occurrence of summer tropical cyclones decreases by 32% and the autumn southwesterly pattern increases by 50% under future climate scenarios based on the high-resolution atmospheric model (HiRAM). This may lead to the accumulation of AOD over China during summer and autumn through dynamic transport. The findings suggest that AOD variations in East Asia may change along with future changes in the large-scale circulation under global warming.

Summary: Parallel evolution is expected among closely related taxa exposed to similar selective pressures, but genetic solutions to achieve phenotypic similarities may differ. In East Asian Paridae species, high-elevation adaptation shows parallel functional response to extreme elevation relying on different genes, with no influence of heterozygosity on genetic parallelism.

Summary: This study used the WRF model to investigate future temperature and precipitation changes in Greece. The model simulations revealed underestimation of maximum temperatures, slight overestimation of minimum temperatures, and a small dry bias in precipitation. The projections showed a robust magnitude of future warming, particularly in the eastern areas of Greece under the RCP8.5 scenario. Future precipitation changes indicated an overall decrease in annual precipitation, with the most dramatic reductions observed under RCP8.5. Increases in the number of hot days and dry days were also projected, particularly in the plain areas of Greece under the RCP8.5 scenario in the far future.

Summary: This study assesses the temporal dynamics of biotic colonization in subtropical East Asian caves. It discovers that the majority of colonizations occurred after the Oligocene-Miocene boundary, and organisms from the surrounding forest were a major source of cave biodiversity. The colonization of these caves was influenced by large-scale seasonal climatic changes and evolution of local forests.

Summary: Most future projections in CMIP5 show more frequent exceedances of the rainfall threshold during El Nino in the eastern equatorial Pacific, but these frequencies vary widely across models, leading to uncertainty in future forecasts. The sensitivity of precipitation to local SST anomalies increases consistently across CMIP-class models, but changes to ENSO-related SST variability can greatly influence the results.

Summary: The effect of air-sea coupling on the European climate simulation is evaluated using a climate type classification. The simulations show that the coupled model captures the observed climate type distributions reasonably well, and also reveals the changes in climate type distribution under future scenarios. Coupling leads to colder climate types in certain regions and drier climates in specific areas. By the end of the 21st century, the climate type distribution changes in more than 50% of the domain, with coupled simulations showing larger changes compared to uncoupled simulations.

Summary: Satellite observations show slight increases in Antarctic sea-ice extent, contradicting climate model predictions. This study finds that the expansion of sea ice is due to cooling of the Southern Ocean surface, which is primarily linked to teleconnections with the tropical Pacific Ocean. The discrepancy between models and observations may be caused by model bias in the forced response and observed tropical variability.

Summary: The 2020 pandemic year witnessed an unprecedented retardation of spring water temperature rising in the northeastern basin of the Yellow Sea. This phenomenon was primarily caused by the significant increase in latent heat releases and exceptional heat fluxes generated by strong northwesterly winds. The warm winter water and oceanic heat redistribution also played a role in supporting the cold anomaly at the surface, resulting in the delayed and suppressed spring bloom.

Summary: This study finds that the weakening of the Indian Ocean Walker circulation (IWC) is accompanied by a positive Indian Ocean Dipole (10D)-like warming pattern and anomalous meridional circulation. The anomalous meridional circulation is linked to enhanced land-sea thermal contrast and is partially responsible for the weakening of the IWC. These findings highlight the important role of local meridional circulation changes in modulating future IWC changes.

Summary: The authors find that persistent two-way teleconnections between the North Pacific Oscillation and the tropical Pacific are a key source of multi-year El Nino events. These teleconnections lead to the prolonged El Nino phenomena, resulting in severe floods and droughts worldwide with significant socioeconomic impacts. Model experiments and future projections suggest that with enhanced NPO variability under future anthropogenic forcing, more frequent multi-year El Nino events should be expected. Therefore, properly accounting for the effects of the NPO on the evolution of El Nino events may improve multi-year El Nino prediction and projection.

Summary: This study explores the mechanisms of dry and moist heatwaves over East Asia using observations, climate change projections, and new generation Earth System models. The research finds that dry heatwaves are amplified by the convergence of wave activity over the region, resulting in surface warming. On the other hand, moist heatwaves are triggered by local anticyclonic anomalies and amplified by cloud and water vapor feedback. Model simulations project an intensification of dry heatwaves and an increase in moist heatwave days in response to rising greenhouse gas concentrations.

Summary: Current climate models have biases in simulating the East Asian summer monsoon, reducing the reliability of monsoon projections under global warming. This study used a higher-resolution coupled climate model and found that simulations with increased CO2 levels better captured regional details and extremes of the monsoon. The results suggest an intensified monsoon response to CO2-induced warming.

Summary: Global heating causes the lengthening of European summer, with the early onset of summer being responsible for this climatic trend. An intensified anti-cyclonic circulation anomaly in late May leads to temperature increases. The intensification of the mid-latitude westerly wind affects the anomalous circulation change through Rossby wave responses. With further global heating, more frequent European heatwaves are expected to occur.

Summary: Mountains play a crucial role in shaping regional and global climate. This study focuses on understanding how mountain precipitation will respond to increasing greenhouse gases. The research findings suggest that mountain warming is more pronounced compared to global and ocean warming. Five low-latitude mountain ranges are identified to have elevation-dependent precipitation response. The proposed Orographic moisture omega feedback hypothesizes that changes in low-level relative humidity can enhance or weaken local precipitation. Changes in mountain precipitation could have significant consequences for hydrology, human societies, and ecosystems.

Summary: Climate change has resulted in more intense tropical cyclones globally, but the rainfall characteristics of these cyclones and their future changes at regional scales are not fully understood. In this study, using high-resolution model simulations, we investigate the factors that control the rainfall characteristics of landfalling tropical cyclones in the North Indian Ocean and western-North Pacific and their response to increasing atmospheric CO2 concentrations. Our results show that rainfall intensity and area behave differently in these regions, with rainfall intensity increasing more than area in the North Indian Ocean and the opposite in the western-North Pacific. We identify the key factors that influence rainfall intensity and area, highlighting the need for regional-scale adaptation strategies for future changes in landfalling tropical cyclones rainfall.
