Based on the hindcasts from five subseasonal-to-seasonal (S2S) models participating in the S2S Prediction Project, this study evaluates the performance of the multimodel ensemble (MME) approach in predicting the subseasonal precipitation anomalies during summer in China and reveals the contributions of possible driving factors. The results suggest that while single-model ensembles (SMEs) exhibit constrained predictive skills within a limited forecast lead time of three pentads, the MME illustrates an enhanced predictive skill at a lead time of up to four pentads, and even six pentads, in southern China. Based on both deterministic and probabilistic verification metrics, the MME consistently outperforms SMEs, with a more evident advantage observed in probabilistic forecasting. The superior performance of the MME is primarily attributable to the increase in ensemble size, and the enhanced model diversity is also a contributing factor. The reliability of probabilistic skill is largely improved due to the increase in ensemble members, while the resolution term does not exhibit consistent improvement. Furthermore, the Madden-Julian Oscillation (MJO) is revealed as the primary driving factor for the successful prediction of summer precipitation in China using the MME. The improvement by the MME is not solely attributable to the enhancement in the inherent predictive capacity of the MJO itself, but derives from its capability in capturing the more realistic relationship between the MJO and subseasonal precipitation anomalies in China. This study establishes a scientific foundation for acknowledging the advantageous predictive capability of the MME approach in subseasonal predictions of summer precipitation in China, and sheds light on further improving S2S predictions.

Catalyst–support interaction plays a crucial role in improving the catalytic activity of oxygen evolution reaction(OER).Here we modulate the catalyst–support interaction in polyaniline-supported Ni_(3)Fe oxide(Ni_(3)Fe oxide/PANI)with a robust hetero-interface,which significantly improves oxygen evolution activities with an overpotential of 270 mV at 10 mA cm^(-2)and specific activity of 2.08 mA cm_(ECSA)^(-2)at overpotential of 300 mV,3.84-fold that of Ni_(3)Fe *** is revealed that the catalyst–support interaction between Ni_(3)Fe oxide and PANI support enhances the Ni–O covalency via the interfacial Ni–N bond,thus promoting the charge and mass transfer on Ni_(3)Fe *** the excellent activity and stability,rechargeable Zn-air batteries with optimum Ni_(3)Fe oxide/PANI are assembled,delivering a low charge voltage of 1.95 V to cycle for 400 h at 10 mA cm^(-2).The regulation of the effect of catalyst–support interaction on catalytic activity provides new possibilities for the future design of highly efficient OER catalysts.

基于落锤冲击试验和数值模拟研究了侧向冲击下圆形双钢管混凝土(concrete-filled double-tube, CFDT)柱的损伤模式;以弯矩-转角关系作为评估指标,建立了圆形CFDT柱的冲击质量-冲击速度、冲击能量-冲击质量损伤评估模型;讨论了冲击位置、外钢管强度、内钢管径厚比和轴压比等参数对损伤评估模型的影响规律。结果表明:在冲击能量不变的情况下,圆形CFDT柱的损伤程度随冲击质量与冲击速度比值的增大而显著增加。圆形CFDT柱的临界冲击能量曲线随冲击质量的增大逐渐下降后趋于平缓,收敛于水平渐近线;不同损伤程度对应的临界冲击能量间存在显著差别。当冲击质量恒定时,增大内钢管径厚比、外钢管强度以及冲击点距自由端距离,可以提高圆形CFDT柱的临界冲击能量;增大轴压比则会使临界冲击能量呈先增大后减小的趋势。各参数对临界冲击质量的影响随着冲击速度的增大而减小,其中外钢管强度对损伤评估模型的影响最大,轴压比和冲击位置次之,内钢管径厚比的影响最小。
