Analysis of the Mechanism Underlying Tibetan Plateau Vortex Frequency Difference between Strong and Weak MJO Periods

引用

Journal of Meteorological Research 2017年第3期31卷 530-539页

作者： guoping LI Fuhu zhao School of Atmospheric Sciences Chengdu University of Information Technology Collaborative Innovation Center on Forecast and Evaluation of Meteorological Disasters Nanjing University of Information Science &Technology Chongqing Meteorological Observatory

In this paper, the NCEP/DOE reanalysis data, OLR data from NOAA, Australian Meteorological Bureau real-time multivariate MJO index, and Tibetan Plateau vortex （TPV） statistical data from the Chengdu Institute of Plateau Met- eorology, are used to discuss the modulation of the TPV by the MJO, through applying the wavelet analysis and com- posite analysis. The results show that：（1） The MJO plays an important role in modulating the TPV, as the number of TPVs generated in strong MJO periods is three times that in weak periods. （2） During strong （weak） MJO periods, the Tibetan Plateau （TP） is in control of a low-frequency, low-pressure cyclone （high-pressure, anticyclone） system, and thus the atmospheric circulation conditions over the plateau are conducive （inconducive） to the generation of TPVs. （3） During strong （weak） MJO periods, southerly （northerly） winds prevail in the east of the TP, while north- erly （southerly） winds in the west. Over the northern part of the TP, easterly （westerly） flow is predominant, while westerly （easterly） flow prevails over the south, thus conducive （inconducive） to the formation of cyclonic circula- tion （i.e., TPVs） at low altitude over the TP. （4） In strong MJO periods, water vapor is relatively less abundant over most of the TP, inconducive to the generation of TPVs; however, moisture transported by the south branch trough and the low-frequency, high-pressure anticyclone system from the Bay of Bengal, are very important for the develop- ment of TPVs. As the strength of the MJO changes continuously during its eastward propagation, the inten- sity of tropical convection and vertical circulation structures of the tropical atmosphere also change accordingly. Al- ternation between favorable and unfavorable conditions for the generation of TPVs occurs, thus resulting in signifi- cant frequency differences of TPVs between strong and weak MJO periods.

Full characterization of the embedding relations between α-modulation spaces

Science China Mathematics 2018年第7期61卷 1243-1272页

作者： Weichao Guo Dashan Fan guoping zhao School of Mathematics and Information Sciences Guangzhou University Department of Mathematics University of Wisconsin-Milwaukee School of Applied Mathematics Xiamen University of Technology

In this paper, we consider the embedding relations between any two a-modulation spaces. Based on an observation that the a-modulation space with smaller a can be regarded as a corresponding decomposition space associated with a-covering for larger a, we give a complete characterization of the Fourier multipliers between a-modulation spaces with different a. Then we establish a full version of optimal embedding relations between a-modulation spaces.

MODEL REDUCTION AND ACTIVE CONTROL FOR A FLEXIBLE PLATE

引用

Acta Mechanica Solida Sinica 2011年第5期24卷 467-476页

作者： Yong Xie Tong zhao guoping Cai Department of Engineering Mechanics State Key Laboratory of Ocean Engineering Shanghai Jiaotong University Shanghai 200240 China

The internal balance technique is effective for model reduction in flexible structures, especially those with dense frequencies. However, due to the difficulty in extracting the internal balance modal coordinates from the physical sensor readings, research so far on this topic has been mostly theoretic and little on experiment or engineering applications. This paper, by working on a DSP TMS320F2812-based experiment system with a flexible plate and bringing forward an approximating approach to accessing the internal balance modal coordinates, studies the internal balance method theoretically as well as experimentally, and further designs an active controller based on the reduced model. Simulation and test results have proven the proposed approximating approach feasible and effective, and the designed controller successful in restraining the plate vibration.

Rebuilding the Chinese Soul:Some Considerations for Education

作者： guoping zhao College of Education Oklahoma State UniversityStillwaterOK 74078USA

This paper tackles the issue of education as the process of person-making and attempts to redefine the ideal and unique Chinese person-the Chinese soul-based on a civilizational dialogue and synthesis that would transform modern education and enable education to play a central role in“redeeming modernity”and revitalizing Chinese *** paper briefly analyzes the historical efforts,and failures,to reform the Chinese soul and argues that the 150-year effort to revitalize Chinese culture and transform the Chinese people by way of adopting certain aspects of Western civilization has mostly failed because a sufficiently coherent and meaningful synthesis of the two civilizations was lacking.

Microbes: the hidden giant behind the biogeochemical cycling of elements in the hydrosphere

引用

Science China(Life Sciences) 2019年第10期62卷 1271-1274页

Microbes are the oldest inhabitants of Earth. Through billions of years of coevolution with Earth, these creatures, usually invisible to the naked eye, have contributed to shaping the Earth surface, creating an ecosystem habitable for higher organisms including humans. By some estimates, microbes account for up to half of the biomass on the planet today (Whitman et al., 1998). They thrive in every corner of Earth, including harsh habitats such as hot springs, hydrothermal vents, salt and soda lakes, acid mine drainage, deep subsurface, and thus define the boundaries of the biosphere. Microbes also exhibit immense genetic and metabolic diversity. Therefore, it is not surprising that these organisms play a pivotal role in driving elemental cycling on Earth, a process essential for maintaining the habitability of the planet Earth.
