Analysis of future climate variability under CMIP6 scenarios based on a downscaling method considering wet days in the upper Yangtze River basin, China - Theoretical and Applied ClimatologyAccording to recent studies, the past decade was the hottest on record, and climate change is accelerating. As part of the Yangtze River Basin, the largest river basin in China, the Upper Yangtze River Basin (UYRB) plays a crucial role as the primary source of hydropower. However, the UYRB is also one of the most climate-sensitive regions within the basin, making the impact of climate change on this area particularly critical. We downscaled CMIP6 GCMs’ outputs of precipitation (including wet/dry spells sequence correction), and temperature projections (2024–2100), under four typical Shared Socioeconomic Pathways (SSPs), and we pursued a trend analysis upon these potential future climate series. We found significant upward trends in temperature across all SSPs in August, but no significant trends in precipitation for the same month. Additionally, for SSP370 and SSP585, there are significant upward trends in temperature in December, while precipitation showed no significant trends during that month. This may result in drier winters than now, increased potential evapotranspiration, and reduced surface (snow) water storage, impacting water resources availability. Consecutive dry/wet days at station, and basin scale show spatial-temporal heterogeneity, but generally wet spells are longer, and dry spells shorten moving from South-East to North-West.

"Statistical downscaling of GCMs wind speed data for trend analysis of future scenarios: a case study in the Lombardy region"

Statistical downscaling of GCMs wind speed data for trend analysis of future scenarios: a case study in the Lombardy region - Theoretical and Applied ClimatologyNear-surface wind speed is a key climatic variable, affecting many sectors, such as energy production, air pollution, and natural hazard. Lombardy region of Italy is among the European areas with lowest average wind speed, leading generally to low air quality and wind energy potential. However, it is also one of the most affected area by tornadoes in Italy. Here we investigate possible changes in wind circulation as due to prospective global warming. We analysed wind speed WS under future scenarios (SSP1-2.6 and SSP5-8.5) from six Global Climate Models (GCMs) until 2100, tuned against observed WS data. We employed a statistical downscaling method, namely Stochastic Time Random Cascade (STRC) to correct locally GCMs outputs. Three statistical tests, i.e. Linear Regression, Mann Kendall, Moving Window Average, were carried out to analyse future trends of: annual WS averages, 95th quantile (as an indicator of large WS), and the number of days of calm wind per year (NWC). The proposed STRC algorithm can successfully adjust the mean, standard deviation, and autocorrelation structure of the GCM outputs. No strong trends are found for the future. The chosen variables would all display non-stationarity, and the 95th percentile display a positive trend for most of the stations. Concerning NWC, notable discrepancies among GCMs are seen. The STRC algorithm can be used to successfully adjust GCMs outputs to reflect locally observed data and to then generate credible long-term scenarios for WSs as a tool for decision-making.
