Summary: This study examines the characteristics of tropical cyclone activity using a regional climate model, finding significant increases in TC frequency in certain regions under future climate conditions. The study also notes a decrease in TC frequency in other regions, highlighting the need for further research to address uncertainties in TC projections.

Summary: Assessing the potential impacts of climate change on river flows is crucial for adaptation. A study comparing convection-permitting models (CPMs) and regional climate models (RCMs) for simulating river flows in the UK found that before bias correction, CPMs generally perform better than RCMs. Bias correction of precipitation improved the performance of both models. In terms of future flow projections, CPMs consistently projected higher flow changes than RCMs. However, the limited availability of CPM data in comparison to RCM/GCM data poses challenges for its wider application in adaptation planning.

Summary: This study analyzed rainfall projections in Egypt in the context of climate change. The results showed that the empirical quantile mapping method was the most appropriate for correcting rainfall projections. The findings indicated significant increases in rainfall at most locations, with the western part of the country being the most affected. These results are important for understanding the potential impacts on Egypt's development.

Summary: This study analysed precipitation and temperature biases from a set of Regional Climate Models in the South American CORDEX domain. The results showed a warm bias in central Argentina during the summer season, possibly due to an overestimation of incoming shortwave radiation. The models also overestimated precipitation in the northeast of Brazil during summer, which could be attributed to underestimation of moisture flux convergence and relative humidity at lower levels. These biases could affect the climate change signal and are linearly linked with warming levels in the models, with statistical significance at 95% confidence level.

Summary: Climate models now include atmospheric chemistry to provide policy-makers with reliable atmospheric projections. The study combines a new gas-phase module with a regional climate model to improve predictions of chemical species. Results show improvements in surface carbon monoxide and tropospheric ozone, but limitations in predicting organic products suggest further development is needed. Despite this, the new gas-phase scheme represents an important advancement in atmospheric chemistry modeling within a regional climate model.

Summary: The study investigates the sensitivity of meteorological factors in the western Tianshan Mountains region in China to different cumulus convection schemes in climate models. Results show that different combinations of cumulus convection schemes can improve the simulation performance of meteorological factors in this region, with no significant sensitivity observed. In both annual and seasonal simulations, the RUN2 scheme performs particularly well for temperature variables.

Summary: The study found that mineral dust emissions from the Sahel-Saharan zone have led to a decrease in temperature extremes, including warm days, very warm days, and warm nights over the Sahel. The accumulation of mineral dust particularly impacts the northern Sahel region.

Summary: Water purification is essential to wetlands, but climate change may have varying effects on peatlands and constructed wetlands. Warmer conditions could lead to different responses in terms of water quality, with constructed wetlands benefiting from a higher purification function under extreme climate scenarios while peatlands may deteriorate.

Summary: The study showed that the humid region had the largest contribution to the national NPP IAV in China, accounting for 62%, primarily influenced by daily temperature range and precipitation. Water-limited regions, such as semi-humid, semi-arid, and arid areas, were mainly impacted by precipitation, high temperature days, and normal precipitation. In the Tibetan Plateau, daily temperature range and precipitation exerted the greatest influence on NPP IAV.

Summary: The compound effects of drought and heat, being one of the greatest hazards related to climate change, are studied in this research using an ensemble of CORDEX regional climate models (RCMs). The evaluation against the E-OBS gridded data set shows that the RCMs are able to reproduce the spatial pattern of the dry-hot season length, but the simulated seasons tend to start later and underestimate the interannual variability of their length. Future projections indicate a significant prolongation of the dry-hot seasons in the Mediterranean and Western Europe, regardless of the concentration pathway.
