Contrasting the Skills and Biases of Deterministic Predictions for the Two Types of El Nio

Advances in Atmospheric Sciences 2017年第12期34卷 1395-1403页

作者： Fei ZHENG jin-yi yu International Center for Climate and Environment Science Institute of Atmospheric PhysicsChinese Academy of Sciences Collaborative Innovation Center on Forecast and Evaluation of Meteorological Disasters Nanjing University of Information Science and Technology Department of Earth System Science University of California

The tropical Pacific has begun to experience a new type of El Nio, which has occurred particularly frequently during the last decade, referred to as the central Pacific(CP) El Nio. Various coupled models with different degrees of complexity have been used to make real-time El Nio predictions, but high uncertainty still exists in their forecasts. It remains unknown as to how much of this uncertainty is specifically related to the new CP-type El Nio and how much is common to both this type and the conventional Eastern Pacific(EP)-type El Nio. In this study, the deterministic performance of an El Nio–Southern Oscillation(ENSO) ensemble prediction system is examined for the two types of El Nio. Ensemble hindcasts are run for the nine EP El Nio events and twelve CP El Nio events that have occurred since 1950. The results show that(1) the skill scores for the EP events are significantly better than those for the CP events, at all lead times;(2) the systematic forecast biases come mostly from the prediction of the CP events; and(3) the systematic error is characterized by an overly warm eastern Pacific during the spring season, indicating a stronger spring prediction barrier for the CP El Nio. Further improvements to coupled atmosphere–ocean models in terms of CP El Nio prediction should be recognized as a key and high-priority task for the climate prediction community.

El Nio–Southern Oscillation and its impact in the changing climate

National Science Review 2018年第6期5卷 840-857页

作者： Song Yang Zhenning Li jin-yi yu Xiaoming Hu Wenjie Dong Shan He School of Atmospheric Sciences Sun Yat-sen University Guangdong Province Key Laboratory for Climate Change and Natural Disaster Studies Sun Yat-sen University Institute of Earth Climate and Environment System Department of Earth System Science University of CaliforniaIrvine CAUSA

Extensive research has improved our understanding and forecast of the occurrence, evolution and global impacts of the El Nio–Southern Oscillation(ENSO). However, ENSO changes as the global climate warms up and it exhibits different characteristics and climate impacts in the twenty-first century from the twentieth century. Climate models project that ENSO will also change in the warming future and have not reached an agreement about the flavor, as to the intensity and the frequency, of future ENSO *** article presents the conventional view of ENSO properties, dynamics and teleconnections, and reviews the emerging understanding of the diversity and associated climate impacts of ENSO. It also reviews the results from investigations into the possible changes in ENSO under the future global-warming scenarios.

Analysis on Plant and Quality Traits in an Improved Population of Corn

Journal of Northeast Agricultural University(English Edition) 2006年第2期13卷 97-103页

作者： jin yi yu Tianjiang DONG Ling WANG Zhenhua ZHANG Lin College of Agriculture Northeast Agricultural University Harbin Heilongjiang 150030 PRC

An improved population NEAU 2 was tested in Triple Test Cross design to analyze the genetic structure of 31 plants and quality traits. The results suggested that additive effect played an important role in all of these traits except for filling property trait V1. Nine traits such as grain yield and volume weight were determined mainly by the additive effect. Globulin and starch content were controlled by significant dominant effect. The leaf number above ear and most quality traits studied were controlled by both additive and dominance effect, and 4 traits such as 100 kernel weight were determined by both additive and epistasis effect. However, the heredity of plant height, ear position, and so on was determined by all these kinds of genetic effects. In quality improvement, direct selection could increase the content but not improve the quality of corn protein. Direct selection for albumin content and the ratio of glutelin to zein was effective and might be a better way to improve the protein quality of corn. Starch content might be raised by direct selection, but it might increase the content of amylopectin meanwhile. It was better to increase gross fat content by direct and indirect selection through the weight ratio of embryo to endosperm, which might also be effective to increase gross fat.

Corn Heterotic Group and Model in Heilongjiang of China

引用

Journal of Northeast Agricultural University(English Edition) 2009年第3期16卷 93-96页

作者： jin yi DONG Ling yu Tianjiang LI Yan GUO Ran College of Agriculture Northeast Agricultural University Harbin 150030 China

The concept and research achievements of the heterotic group and model in corn were introduced briefly. The results showed that the domestic corn germplasm could be divided into three main heterotic groups and two main heterotic models. The research on corn germplasm in Heilongjiang Province could be concluded as three main heterotic groups and three main heterotic models. Some new opinions about corn heterotic group and heterotic model in Heilongjiang Province were proposed such as Northeast group and NortheastxLancaster model.

Degradation of diphenyl chlorophosphate by using ozone

引用

Journal of Chemistry and Chemical Engineering 2009年第4期3卷 8-17页

作者： ZHOU Jian-jun WU Chun-du CHU jin-yu yi Cheng-wu School of the Environment Jiangsu University Zhenjiang 212013 China

Diphenyl chlorophosphate （DPCP）, which acts as a simulant of nerve warfare agent, is decontaminated by ozone in this study. Experimental results show that DPCP can be degraded rapidly by ozone. In the optimum working conditions, 99% 50 mg/L DPCP are degraded in 16min, and 30% total organic carbon of the solution is reduced. The free radical accelerant, Fe2＋, and inhibitors, 2-propanol and tert-butanol significantly influence the degradation efficiency of DPCP, therefore, free radical is the most important oxidant for the DPCP degradation reaction in this system. Ozone can be decomposed to hydroxyl radical, which would attack DPCP to start the degradation reaction. Furthermore, parts of DPCP would be mineralized, and degradation of toluene probably is the controlling step of the mineralization of DPCP. Finally, the reaction pathways are predicted for the degradation of DPCP by ozone.
