    Mechanisms linking river flow regime and riparian hardwood establishment by Steven F. Railsback, John H. Bair

    Published 2025-01-01
    “…A more complete conceptual model of hardwood establishment considers that seeds need to be deposited where soil is moist long enough to develop roots but far enough from the water's edge to avoid mortality in flow fluctuations; for soil moisture to remain within reach of roots, which could require unusually steady flows, a high capillary fringe, or favorable groundwater gradients; and to avoid mortality due to scour or inundation in winter high flows. Model sensitivity and lack of literature suggest the time and moisture requirements for seeds to develop roots and inundation mortality of seedlings as research priorities.…”

    Study on the driving mechanism of spatio-temporal non-stationarity of vegetation dynamics in the Taihangshan-Yanshan Region by Jiao Pang, Minli Wang, Huicong Zhang, Liyao Dong, Jiarui Li, Yanrui Ding, Zhenzhou Zhu, Feng Yan

    Published 2025-01-01
    “…From 2001 to 2020, kNDVI in spring, summer and autumn showed a slow upward trend and a downward trend in winter. In terms of space, vegetation coverage in Yanshan region is generally higher than that in Taihang Mountain with significant spatial heterogeneity.(2) Theil-Sen Median trend and Hurst index analysis shows that about 70% of regions have shown an increasing trend in kNDVI throughout the year and will continue to increase in the future. (3) The analysis results of Optimal Parameter Geodetector Detectors (OPGD) show that evapotranspiration (ET) is the dominant driving factor of kNDVI, and the interactive enhancement benefits with other factors is significant. …”

    Weather resilience of the future Swiss electricity system with very high shares of variable renewable energy sources by Collin Killenberger, Nik Zielonka, Jan-Phillipp Sasse, Evelina Trutnevyte

    Published 2025-01-01
    “…We find that solar PV capacity of 35 GW in Switzerland in 2035 without any wind power would allow the country to reach its target of 35 TWh yr ^−1 on new renewable electricity in 95% of the 25 historical weather years. Further limiting winter electricity import to a maximum of 5 TWh yr ^−1 as currently envisioned by policy, would require additional 10 GW of wind power to have a comparable level of weather resilience. …”

    Published 2018-01-01
    “…Based on five evaluation indexes, NRMSE (Normalized Root Mean Square Error), NSE (Nash-Sutcliffe), FAR (False Alarm Ratio), UR (Underreporting Rate), and CSI (Critical Success Index), the monthly GPM products showed the best performance, better than GPM-HH products and GPM-D products. (2) The performance of GPM products in summer and autumn was better than in winter and spring. However, the GPM satellite’s precision in undulating terrain was poor, which could easily lead to serious errors. (3) CDF models were successfully used to modify GPM-D and GPM-M products and improve their accuracy. (4) The range of 0–100 mm precipitation could be corrected best, but the GPM-M products were underestimated. …”
