Summary: The analysis of temperature extreme indices in southern South America showed that the largest positive trends were observed in the tropical nights index, with a clear anthropogenic signal in the subtropical and Andes regions. Significant changes in Patagonia were attributed to anthropogenic forcing, while projected changes for the 21st century are consistent with a warming climate, particularly in warm nights indices.

Summary: This study focuses on the construction of an unprecedented multi-model ensemble of statistically downscaled global climate models (GCMs) for daily precipitation. The results show that statistical downscaling adds value in representing the main features of daily precipitation and can predict future changes in precipitation. Furthermore, the statistical downscaling projections show consistent agreement with the dynamical downscaling results in terms of change direction but have differences in intensity.

Summary: If effective mitigation measures are not taken, ongoing global warming will continue throughout the century. This is associated with the occurrence of extreme climate events in Africa. Using model data from 24 CMIP6 modeling centers, this study investigates future changes in extreme climate events over Africa under different global warming levels. The results show that additional warming amplifies the impact of climate extremes, stressing the need for ambitious climate change mitigation measures to limit global warming.

Summary: Improved understanding of the sources of uncertainty in Arctic sea ice projections is crucial for assessing the impacts of changing Arctic environment. This study finds that internal variability, model structure, and emissions scenario all play significant roles in predicting Arctic sea-ice area. Internal variability has a larger impact on uncertainty in the short term, while emissions scenario becomes dominant over longer time scales. Additionally, there is a considerable dependency of model uncertainty on the season, with larger uncertainties in winter months.

Summary: This study investigates trends in the pluviometric regime in North and South Carolina, USA using data from forty-four historical stations. The results show that most of the stations do not exhibit consistent, statistically significant trends in precipitation amount, frequency, and intensity. However, a third of the stations show a significant increasing trend in the annual number of light rain days. These findings contribute to the understanding of trends in the southeastern United States and have implications for adaptation planning.

Summary: Compound hot and dry events have greater impacts than individual extreme events, and understanding their physical mechanisms is important for early warning. This study assesses the ability of global climate models to simulate these events in South America and investigates potential future changes. The historical period shows overestimation of hot/dry events by reanalysis, while the ensemble median of GCMs performs better. Future projections suggest longer heat waves and increased frequency of compound events in southern SA. Different sea surface temperature anomalies patterns are associated with these events in tropical and extratropical SA.

Summary: Convection-permitting models have the potential to provide localized future climate information, but the gap between computational and effective resolution limits their full benefit. However, in regions with strong surface heterogeneity, fine-scale projection detail may persist close to the grid scale. Analysis of a 4.5-km resolution projection for Africa reveals statistically significant detail in areas of high topographic variability and along lake coastlines.

Summary: This study presents local sea-level projections for South Asia and explores the drivers of spatial variations in sea-level change over the 21st century under different scenarios. It finds that the sterodynamic contribution and future groundwater extraction are the main drivers of sea-level change in the region. These projections provide valuable information for coastal planning decisions by local communities, government, and industry.

Summary: This study investigates the changes in East Asian summer monsoon precipitation during the mid-Holocene using data-model comparison and dynamic analysis. The results show that the dynamic effect, rather than the thermodynamic effect, is the dominant control in the increased monsoon precipitation, with the enhancement of horizontal moisture transport being the main factor.

Summary: This paper evaluates the predictability and skill of the models from the NMME project in South America, and finds that temperature predictability is higher than precipitation predictability. The multi-model ensemble signal dominates temperature variance in autumn and summer, while inter-model biases dominate in spring and winter. The highest predictability of precipitation is found in tropical latitudes.

Summary: This study examines the impact of dynamic and thermodynamic drivers on rainfall patterns and vegetation in the Tropical Andes. The results show that both drivers play a role in determining rainfall patterns, with upper-level wind circulation being crucial in the mountains but not in the lowlands. Additionally, only 5-7 day dry spells have a prolonged effect on vegetation in the semi-arid Andes.

Summary: This study investigates the influence of boreal winter-peaked La Nina on the precipitation in East Asia during the following summer. It is found that the impact is mediated through intermediate sea surface temperature (SST) anomalies, particularly Z-shaped cold SST anomalies in the tropical North Pacific. The SST anomalies can operate through three main mechanisms: tropical atmospheric perturbations, perturbations created through the monsoon trough, and perturbations over the tropical Atlantic-northwest Africa.

Summary: Extreme rainfall has a significant impact on rice yield in China, resulting in reductions comparable to those caused by extreme heat. The main mechanisms of these impacts are the limitation of nitrogen availability for tillering and the physical disturbance on pollination. Projection suggests an additional 8% yield reduction due to extreme rainfall under warmer climate by the end of the century. These findings emphasize the importance of considering extreme rainfall in food security assessments.

Summary: Large-scale cultivation of bioenergy crops can lead to land cover changes and biophysical effects on climate, altering the global water cycle and energy balance. However, it is found that global land precipitation increases under bioenergy scenarios, partially compensating for the water consumption by these crops. Therefore, a more comprehensive assessment is highly recommended for effective climate mitigation policies.

Summary: The advection fog characteristics at Qingdao Liuting International Airport during 2000-2022 were analyzed using surface observation, sounding, and reanalysis data. Two types of fog were identified: evaporation fog (EF) dominated by northwesterly wind in winter, and cooling fog (CF) dominated by southeasterly wind in spring and summer. The formation and properties of EF and CF are influenced by different planetary boundary layer structures and sea-land-atmosphere interactions.

Summary: This study introduces a method of constructing a constrained multi-model ensemble to improve the reliability of near-land-surface air temperature projections. The results show that the constrained ensemble reduces the global-scale temperature change by less than 0.05℃/century compared to the raw ensemble. However, the regional results exhibit a wider range of adjustments, indicating the importance of considering regional impacts. Overall, the constrained ensemble improves the reliability of temperature projections.

Summary: Stable water isotopes are important tracers in the hydrological cycle, and their spatial and temporal distributions are influenced by various factors. In this study, the authors conducted in situ observations of near-surface vapor isotopes over a large region in China, and found that the spatial variations in isotopes are mainly influenced by seasonal mean variations during pre-monsoon and monsoon seasons, but also by synoptic-scale variations during the monsoon period. Factors such as moisture sources, continental recycling processes, and convection play significant roles in controlling the isotopic composition of water vapor in different periods. The results highlight the need to consider regional factors when interpreting proxy records.
