The Coupled Model Intercomparison Project (CMIP) is an international community-based infrastructure that supports climate model intercomparison, climate variability, climate prediction, and climate projection. Improving the performance of climate models over East Asia and the western North Pacific has been a challenge for the climate-modeling community. In this paper, we provide a synthesis robustness analysis of the climate models participating in CMIP-Phase 5 (CMIP5). The strengths and weaknesses of the CMIP5 models are assessed from the perspective of climate mean state, interannual variability, past climate change during the mid-Pliocene (MP) and the last millennium, and climate projection. The added values of regional climate models relative to the driving global climate models are also assessed. Although an encouraging increase in credibility and an improvement in the simulation of mean states, interannual variability, and past climate changes are visible in the progression from CMIP3 to CMIP5, some previously noticed biases such as the ridge position of the western North Pacific subtropical high and the associated rainfall bias are still evident in CMIP5 models. Weaknesses are also evident in simulations of the interannual amplitude, such as El Niño-Southern Oscillation (ENSO)-monsoon relationships. Coupled models generally show better results than standalone atmospheric models in simulating both mean states and interannual variability. Multi-model intercomparison indicates significant uncertainties in the future projection of climate change, although precipitation increases consistently across models constrained by the Clausius-Clapeyron relation. Regional ocean-atmosphere coupled models are recommended for the dynamical downscaling of climate change projections over the East Asia-western North Pacific domain.  相似文献

Thirty years of safety climate research: Reflections and future directions   总被引:1,自引:0,他引:1  
Looking back over 30 years of my own and other safety-climate scholars’ research, my primary reflection is that we have achieved an enormous task of validating safety climate as a robust leading indicator or predictor of safety outcomes across industries and countries. The time has therefore come for moving to the next phase of scientific inquiry in which constructs are being augmented by testing its relationships with antecedents, moderators and mediators, as well as relationships with other established constructs. Whereas there has been some significant progress in this direction over the last 30 years (e.g. leadership as a climate antecedent), much more work is required for augmenting safety climate theory. I hope this article will stimulate further work along these lines.  相似文献

从哲学的基本原理出发,引用地史及水文气象资料探讨了全球气候变化问题,指出全球气候一直在变化;气候变化的动力主要在天在地而不在人;当今的气候变化可能只是气候变化总过程中的一个波动阶段而非永远的趋势,且其变幅并未超出历史上气候变化的范畴。因此,不能断言全球气候变暖是由于人为排放CO2所致。所以对于不同时空条件下的气候变化应当具体矛盾具体分析具体解决,进而提出了中国应对气候变化的对策建议。  相似文献

Although the important role of safety climate in safety outcomes has been established and many studies have been done by scholars in different disciplines and across different cultures, there are still gaps in the literature. The articles in this Special Issue explore the topics of new developments in the conceptualization of safety climate and occupational/industry-focused studies of safety climate, with the goal of identifying different challenges and findings that arise within or across various occupations or industries. We are pleased to have a closing article by Dr. Dov Zohar on “Thirty Years of Safety Climate Research: Reflections and Future Directions.”  相似文献

To further reduce injuries in the workplace, companies have begun focusing on organizational factors which may contribute to workplace safety. Safety climate is an organizational factor commonly cited as a predictor of injury occurrence. Characterized by the shared perceptions of employees, safety climate can be viewed as a snapshot of the prevailing state of safety in the organization at a discrete point in time. However, few studies have elaborated plausible mechanisms through which safety climate likely influences injury occurrence. A mediating model is proposed to link safety climate (i.e., management commitment to safety, return-to-work policies, post-injury administration, and safety training) with self-reported injury through employees' perceived control on safety. Factorial evidence substantiated that management commitment to safety, return-to-work policies, post-injury administration, and safety training are important dimensions of safety climate. In addition, the data support that safety climate is a critical factor predicting the history of a self-reported occupational injury, and that employee safety control mediates the relationship between safety climate and occupational injury. These findings highlight the importance of incorporating organizational factors and workers' characteristics in efforts to improve organizational safety performance.  相似文献

Abstract

Climate change mitigation and adaptation can be perceived as neglected in environmental impact assessment (EIA). In the light of amendments to the European Union EIA Directive (2014), we developed a novel criteria-based review package to assess climate change mitigation and adaptation as documented in environmental statements, and applied this to a sample of 10 transport developments from England. Justifications relating to climate policy, climate science, the effect of climate change on the development and its vulnerability to climate risks were well explained in most projects. Many projects lacked detail of climate change mitigation and adaptation measures and their benefits, whilst evidence of commitment to mitigation and adaptation or to post-decision monitoring was poor or non-existent; reportedly due to costs, time constraints and absence of mandatory requirements. It is recommended that to improve the effectiveness of the consideration of climate change mitigation and adaptation in EIA, the production of guidelines, change of behaviour of EIA practitioners, more holistic consideration of climate change issues, rigorous post-decision monitoring and use of climate change terminology are more widely adopted.  相似文献

This research empirically evaluates safety climate and safety behavior in the passenger ferry context. Using survey data collected from 155 respondents working for passenger ferry companies in Taiwan, hierarchical regression analysis was used to examine the effects of safety climate on self-reported safety behaviors. Confirmatory factor analysis identified five main dimensions of safety climate as measured on a passenger ferry safety climate scale: safety policy, safety motivation, emergency preparedness, safety training, and safety communication. Further, safety training and emergency preparedness were found to positively affect self-reported safety behaviors with respect to safety compliance and safety participation. The study also revealed positive associations among respondents’ age, ferry capacity, and safety compliance. Implications of the study findings for increasing safety in ferry operations and their contribution to the development of safety management are discussed.  相似文献

In the case of the Japanese Alps, it is experientially known that there is a notable snow climate difference between the Japan Sea side mountains and the Pacific Ocean side mountains. For the purpose of improving avalanche safety, we studied the snow climate characteristics using meteorological and snow pit data collected from two study plots in the mountain regions. Ten years of meteorological data and 4–10 years of snow pit data were employed in the study. A snow climate classification scheme proposed in North America was used to determine the snow climate of these study plots. The general snowpack characteristics for each snow climate presented in previous studies were used in the present study to determine the snowpack characteristics of the study plots. Both meteorological and snow pit data suggested that the Japan Sea side mountains have the same characteristics as the maritime snow climate in North America. On the other hand, the Pacific Ocean side mountains have unique characteristics caused by a combination of continental and maritime climate influences. The Pacific Ocean side mountains have similar characteristics to the continental snow climate of North America, however, that climate is different in that it is characterized by a large amount of rainfall and a high predominance of faceted crystals and wet grains. We identified a new snow climate for the Pacific Ocean side mountains of the Japanese Alps, a “rainy continental snow climate.”  相似文献

The use of safety climate measures for needs assessment and interventions has become increasingly popular. However, no research to date has examined whether the meaning and level of safety climate may differ across different groups of interest. This study used multi-group confirmatory factor analyses to investigate the measurement equivalence of a multidimensional safety climate measure across ten construction trade groups (N = 4725). In addition, observed mean differences in safety climate perceptions between trades were examined. Results revealed strong measurement equivalence of the safety climate measure across the construction trade groups. Further, significant mean differences were found between the ten trade groups on all four safety climate scales.  相似文献
