Summary: The Chinese offshore wind energy sector is growing rapidly, with the country expected to become the global leader in installed wind energy capacity. Future projections show varying trends in wind power density depending on the season, and most of the Chinese coastal area is classified as having good or excellent wind energy resources.

Summary: This study projected future changes in extreme climate indices over Central Asia. Changes were calculated for 2071-2100 relative to 1971-2000. The research found that the region would experience warmer and more extreme temperatures with increasing radiative forcing. The lowest daily temperature was simulated to increase by up to 8 degrees, with a more than 12 degree increase projected over Siberia. There would be a strong growth in warm nights and an increase in the days of warm spells, while cold spell duration would decrease. Precipitation totals over the region were expected to reduce by up to 30%, except for increased precipitation over Siberia, the Himalayas, and Tibetan Plateau. Extreme precipitation events would increase by 20% over the whole region, with an 80% increase over high topographical areas.

Summary: The study examines the impact of atmospheric circulation on changes in climate water balance in the Sudetes Mountains and their foreland. The results indicate that despite positive trends for evapotranspiration, the changes in climate water balance were generally statistically insignificant in the period of 1981-2020, except for an increase in the eastern circulation and a negative tendency in the western and southern sectors for some stations. The findings can contribute to further research on water balance in the region.

Summary: The study reveals that future climate scenarios indicate a significant decrease in precipitation and increase in potential evapotranspiration in the Mediterranean region, leading to increased aridity. These changes, combined with intensive farming and tourism, may result in overexploitation of natural resources, water scarcity, and desertification in the region.

Summary: Global warming is expected to impact the hydrological cycle in the Mediterranean region, causing changes in precipitation extremes and a gradient between the north and south. Future projections show significant increases in daily precipitation extremes, with the magnitude being underestimated in drier areas for 100-year extreme events.

Summary: This study investigates the hydrological functioning of wetlands in semi-arid regions of southern Spain using hydrological modeling and field investigations. The results suggest that the hydroperiods of playa-lakes vary depending on the basin bathymetry and response to lithological changes and active faults. The study also demonstrates the sensitivity of ephemeral playa-lakes to climate change and anthropogenic management.

Summary: This study aims to evaluate the accuracy of reanalysis/satellite data in reproducing significant wave height and wind speed, and assess climate simulations over the western South Atlantic. It found that the models have more realistic representation for wind speed and significant wave height in certain areas, and that there are more intense wind and wave extremes in the austral spring and winter near the southeastern coast of Brazil.

Summary: In this study, the performance of the RegCM4 model in simulating the climatology of cyclones near the west coast of South America is assessed. The model is able to reproduce the climatology of cyclones affecting the western coast of South America, although the frequency of certain types of cyclones may be underestimated or overestimated in certain seasons.

Summary: The increase in computational resources has led to the emergence of high-resolution regional climate models. By comparing high-resolution simulations with global simulations and lower-resolution models, the added value of the models can be assessed. Although the gains are limited, the improvement in spatial representation can enhance local atmospheric circulations and land-atmosphere interactions, particularly in coastal areas.

Summary: The CORDEX Flagship Pilot Study ELVIC aims to investigate the evolution of extreme weather events in the Lake Victoria basin and provide improved information for the climate impact community. The study finds that convection-permitting scale simulations show substantial improvements in the representation of moist convective systems, especially in metrics related to deep convection. These models have the potential to be valuable tools for studying future extreme precipitation events in the region.

Summary: In this study, the climatic impact of Amazon deforestation on South America was analyzed for positive (PDO+) and negative (PDO-) PDO phases. The results showed that deforestation led to reduced precipitation in northern South America and increased precipitation in southern regions. It was also found that deforestation may create a drier corridor during the rainy season. The study highlights the importance of considering long-term climate simulations to better understand the role of deforestation in the lower frequency variability over South America.

Summary: The Parana Hydrographic Region (PHR) in Brazil is known for its energy generation and consumption, among other ecosystem services. This study aimed to identify hydrological drought events in the PHR from 1979 to 2021 and analyze the anomalous atmospheric circulation patterns associated with them. The study used the standardized precipitation index (SPI) to identify drought episodes and examined the severity, duration, intensity, and peak of these episodes. It also analyzed anomalous atmospheric and oceanic patterns during the drought periods. The results revealed the longest and most severe drought in the PHR started in 2016, with no identified end by the analyzed period. The study also identified dry periods during the wet season in three specific years: 2016/2017, 2019/2020, and 2020/2021, each associated with different circulation patterns and oceanic conditions.

Summary: The hydrological response of a subtropical catchment in Serra da Mantiqueira, Brazil, and its four sub-catchments were investigated. Baseflow played a vital role in sustaining streamflow during the dry and wet seasons. Soil moisture did not synchronize with streamflow, showing increases in early wet season followed by streamflow increase and decreases in late wet season followed by streamflow decrease. The study provided consistent estimates of flows and threshold behaviors, contributing to understanding runoff generation at the catchment scale.

Summary: High-resolution simulations were conducted using RegCM4.7 and CLM4.5 models to evaluate their performance in simulating historical and future climate change over tropical South America. The results show that RegCM4.7 has added value in representing the spatial characteristics of precipitation and temperature in certain regions. However, there are still limitations in simulating precipitation over the Amazon Basin, particularly in summer.

Summary: According to 30-year probabilistic simulations, it was found that there is a high probability (28.5%) of large ships dumping oil along the South Atlantic route. Within the Brazilian Exclusive Economic Zone, there is approximately a 62% probability of dumped oil/waste reaching the coastline, with the probability quickly decreasing for Dumping Zones 2 and 3. The equatorial and northeast shores of Brazil are the most vulnerable regions to oceanic dumping.
