Title: The quantitative contrasts between the El Ni駉 and external influence factors beyond the sea and atmosphere

Authors: YANG Zhengling
PP: 872～879
Abstract: It is difficult to explain the continual irregular cycle of El Ni駉 by only the changeful sea and atmosphere, as the change of atmosphere temperature was inconsistent with El Ni駉 in the past millions of years. This implies that there are some external influence factors with relative stable change cycles which drive the changeful sea and atmosphere to some irregular 2 to 7 years, especially the about-4-year cycles. Also, the 2 to 7 years cycle band should be around the relative stable change cycles of external influence factors. The spectra and wavelet analyses show that the volcano, solar, greenhouse gas, tropospheric, LOD, sun spot are not the stable external influence factors.

Title: Effects of lateral boundary conditions on the stability of the atmospheric flow

Authors: TAN Benkui, ZHANG Wenxian, SUO Lingling
PP: 864～871
Abstract: A channel model was usually chosen in the study on the stability problems of the large-scale atmospheric flow, in which the flow was confined by two vertical rigid walls located at different latitudes. In the past, the boundary conditions at the two walls were that the normal component of the geostrophic flow vanished. In this paper, the boundary conditions at the walls are modified to be that the normal component of actual flow vanishes. The new boundary conditions combined with the normal mode method are used to re-study the stability of the large-scale atmospheric flow and new criteria for instability for the barotropic, baroclinic or mixed barotropic-baroclinic flow. It is shown that the status of both the basic flow and the perturbations at the walls may influence the stability of the atmospheric flow, which differs from the classical stability theory where the stability of the flow has nothing to do with the status of the basic flow and perturbations at the walls.
Keywords: meteorology; stability of the atmospheric flow; barotropic and baroclinic stability; effects of the lateral boundaries

Title: Impact of international high oil prices on China’s petroleum supply security strategy: and nessesity of domestic refined oil price

Authors: CHEN Guangjiu, ZHANG Bin
PP: 930～934
Abstract: The paper uses literature research and comparison method to analyze the impact of international high oil prices on China’s petroleum supply security strategy from the view angle of petroleum supply security. The international petroleum supply interruption and price increasing will both influence China’s petroleum supply security and normal operation of society and economic. The impact of international high oil prices on China’s petroleum supply security strategy specifically includes that: the increase of petroleum supply cost leads to cost-push inflation; the increase of petroleum import exchange leads influences the national economy increase quality; the increase of petroleum supply risk leads to potential threat of over a barrel. The comprehensive analysis concludes that it is necessary to increase domestic refined oil price. Appropriate increasing of the domestic refined oil price can compress domestic oil consumption to some extent, encourage people to improve the oil using efficiency, and promote the development of low power consumption products. The increase of domestic oil prices will promote the development of other alternative energy industries, which will help to promote and stimulate the rapid development of new energy. In addition, the increase of domestic oil prices will depress the international crude oil prices increase, help to increase the profits of domestic producers, increase domestic oil supply, and protect the domestic market supply.
Keywords: managerial economics; petroleum supply security strategy; theoretical study; refined oil prices

Title: Empirical research on credit rating transition matrix based on economic cycle

Authors: LI Jingyi，QIN Xuezhi
PP: 924～929
Abstract: This paper studies the construction of credit rating transition matrix based on economic cycle and Z-score model. Using the actual data of listed companies from 1993 to 2007 in China, the paper constructs credit rating transition matrices of different economic cycles. Then the paper analyses these credit rating transition matrices and draws a conclusion that credit rating transition matrix in China has a poor stability and different economic cycles have different credit risks. Finally, this paper suggests that financial institutions adopt prudent credit policies in the recession and loose credit policies step by step in time of economic recovery, depression and prosperous economy. And this paper suggests the government should provide a stable external environment and perfect system for listed companies.

Title: Thermoelectric hypothesis for cause of geothermal anomaly of ice caves in summer

Authors: CAO Caifang
PP: 912～918
Abstract: To investigate the formation mechanism of the geothermal anomaly of ice caves in summer, a hypothesis that attributes the geothermal anomaly to the thermoelectric effect from the relevant knowledge of thermoelectricity, mineralogy and geophysics was proposed in this paper. It was suggested that some unexplained abnormal geothermal phenomena may be caused by the Peltier effect when the earth current flows along the interfaces between two conductive minerals. The earth current arises from either a certain natural electric field or the Seebeck potential originating from the underground temperature gradient. When studying how various types of ice caves in summer and other geothermal abnormity form, the paper formulated several simple circuit models to conjecture the possible underground circuits, and thus successfully explained the presently known abnormal geothermal phenomena by thermoelectric effects.
Keywords: geophysics; geothermal anomaly; ice caves; thermoelectric effect; hypothesis
