Abstract

The accurate identification of precipitation type at ground level is one of the greatest difficulties for forecasters during winter. Special types of precipitation can be a threat to public safety and human health and can disrupt transportation and commerce, causing seriously loss of the economy. Winter precipitation may also cause serious disasters to aircraft navigation. In those situations, the consequences can be catastrophic, with heavy and prolonged freezing precipitation, collapsed power lines causing prolonged power outages, transportation networks of many types completely paralyzed, and even major long-term damage to infrastructure and vegetation in the most severe cases. Therefore, the accuracy of precipitation type is crucial for winter precipitation forecast. Accurate predictions from weather forecast models of timing (onset and duration), intensity, spatial extent, and phase (i.e., precipitation type) are crucial for decision-making and can help minimize the potential impacts. The research progress of precipitation type forecast in recent decades is investigated. The methods and techniques for predicting precipitation phases are reviewed systematically, which can be roughly divided into three categories. The index criterion methods are based on observations, numerical weather prediction weather predictions on thickness, area of warm atmosphere, significance level temperature, regression equation for vertical temperature profile, and model diagnosis. Some of those methods are highly dependent on the accuracy of the numerical model. The second type of methods are based on the microphysical processing scheme of numerical weather prediction model and ensemble prediction system. It includes microphysical scheme method and ensemble prediction method. The last type is the artificial intelligence prediction method including decision tree, artificial neural network, and deep learning etc. In recent years, sophisticated microphysical parameterizations schemes are widely used in high resolution regional forecast models, which help with precipitation-type prediction. The forecast accuracy of precipitation type model has been improved, which has become an important product support in precipitation type forecast. For instance, the precipitation type prediction product of ECMWF and the probabilistic prediction of precipitation type by ECMWF ensemble prediction. The probabilistic prediction has further improved the prediction skills compared with the deterministic model. However, even with such complex algorithms of NWP, correctly predicting what phase of precipitation ends up at the ground remains a challenging task. Besides this, many researches on the formation mechanism of microphysical processes are difficult to be applied to the precipitation type prediction, so it still needs continuous efforts to apply these achievements to improve the precipitation type prediction skill of numerical prediction model and increase the accuracy of precipitation type prediction by artificial intelligence and other technologies.

Abstract

Stormwater resources are not effectively utilized in many Chinese cities, which not only wastes water resources but has also brought about serious urban flooding problems. Urban green space, as a resilient approach of stormwater regulation and storage, has been widely applied in urban flooding control and sponge city construction. Through a review on relevant literature in the past two decades, this paper systematically compares the methods commonly used in the assessment on stormwater regulation and storage capacity of urban green space, examines the pattern factors affecting the capacity, and expounds the application of urban green space in stormwater management at different scales. The literature review aims to provide a scientific basis for the alleviation of urban flooding problems and the construction of sponge cities. Meanwhile, the paper also puts forward four development trends in the research on the stormwater regulation and storage function of urban green space. [ABSTRACT FROM AUTHOR]

Abstract

Sepsis is a major cause of death in intensive care units. The purpose of this study was to investigate the effect of resveratrol (RSV) on sepsis-induced acute lung injury (ALI). The underlying molecular mechanisms were deciphered by both in vitro and in vivo experiments. Polymicrobial sepsis was induced in C57BL/6 mice by cecal ligation and puncture (CLP). RSV pretreatment significantly attenuated CLP-induced acute lung injury, which was associated with enhanced expression of VEGF-B. The protective properties of RSV were assayed in lipopolysaccharide (LPS)-stimulated MH-S cells. We determine that RSV administration inhibited the increased production of TNF-α, IL-6, and IL-1β in LPS-stimulated MH-S cells, which was associated with inhibition of the nuclear factor-κB, P38, and ERK signaling pathways. We also provide evidence that RSV administration reduced LPS-induced apoptosis of MH-S cells by altering the unbalance of Bax/Bcl-2 and inhibiting LPS-induced autophagy. The inhibitory effects of RSV on cytokine levels and apoptosis of alveolar macrophages were both blocked by VEGF-B siRNA. Furthermore, RSV administration regulated LPS-induced C5aR and C5L2 expression, revealing an additional mechanism underlying RSV’s anti-inflammatory and anti-apoptosis effects. Collectively, these results demonstrated that RSV was able to protect against sepsis-induced acute lung injury by activating the VEGF-B signaling pathway.
