Analysis of Solar Ultraviolet Radiation in Xilinhot

To further reveal the variation laws of ultraviolet radiation to provide better service for production and people＇s life, based on observation data of solar ultraviolet radiation obtained by Xilinhot National Climate Observatory in 2007-2012, the variation laws of solar ultraviolet radiation and its relationship with meteorological factors in different cloud conditions in Xilinhote were analyzed by using the mathematical and statistical methods and SPSS 11.5 software. The results showed that the solar ultraviolet radiation had obvious daily, seasonal and annual variations; the solar ultraviolet radiation was weak in the morning and evening but strong at noon; the maximum appeared from June to August, while the minimum appeared in November and December. It had significant correlation with total solar radiation, photosynthetically active radiation, air temperature, air humidity and ground temperature （0-5 cm）. At present, the maximum intensity of ultraviolet radiation （UV-B） was 0.20-1.91 W/m2 from January to March and 0.13-1.43 W/m2 from October to De- cember respectively, which were lower than the safety standard for people and animals （2 W/mZ）. However, the maximum might appear from April to September, ranging from 2.02 to 3.39 W/m2, which was easy to bring a threat and harm to people and animals.

Picophytoplankton abundance and community structure in the Philippine Sea,western Pacific

Flow cytometric determinations of the abundance distribution picophytoplankton （i.e. Prochlorococcus spp., orange fluorescence and community structure of Svnechococcus spp. and picoeukaryotes） were used for samples taken from the Philippine Sea in the western tropical Pacific Ocean from September to October of 2004. A fluorescence probe was employed to detect Chlorophyll a （Chl a）. Abundances of Prochlorococcus spp., orange fluorescence Synechococcus spp. and picoeukaryotes ranged from 0.1 to 58×10^3 cells ml^-1, 0.38 to 17×10^2 cells ml^-1 and 0.42 to 26×10^2 cells ml^-1, respectively. Synechococcus spp. and picoeukaryotes co-occurred in relatively shallow water with the maximum abundance observed at 50 to 70 m depth, while Prochlorococcus spp. only occurred in the 70 to 200 m layer. Prochlorococcus spp. was the dominant picophytoplankton population in terms of abundance and biomass. The cell size and carbon biomass content were estimated for the three picophytoplankton groups. In addition, among the three groups of picophytoplankton, the relative contribution of red fluorescence to the total red fluorescence varied with depth. The fluorescence and light scatter properties of individual cells indicated that in the upper 100 m layer, picoeukaryotes were a major contributor to total red fluorescence, while at the depth below 100 m, Prochlorococcus spp. and Synechococcus spp. made an important contribution to the total red fluorescence.

Two anomalous convective systems in the tropical western Pacific and their influences on the East Asian summer monsoon

By decomposing outgoing Iongwave radiation through empirical orthogonal function （EOF） analysis, the authors identify two anomalous convective systems in the tropical western Pacific. Besides the classical convective system near the Philippines （PC）, there is another convective system near the Federated States of Micronesia （MC）. As the first EOF component in this region, the variance explained by MC is higher than that by PC. Both MC and PC are regulated by the tropical sea surface temperature （SST） anomalies. While PC is associated with an El Ni^o event, MC is correlated with SST anomalies in the central and eastern Pacific during summer. It is also found that the East Asian summer monsoon （EASM） is influenced by these two convective systems. In general, enhanced （suppressed） convection corresponds to an eastwards （westwards） western Pacific subtropical high with weak （strong） intensity. Besides, the summer monsoon rainfall from the Yangtze River basin to Japan tends to increase （decrease） when PC is suppressed （enhanced）. By comparison, the influence of MC is generally weak, with vague signals in the East Asian continent. Moreover, the influence of suppressed convection on the EASM is more significant than that of enhanced convection.

The Treaty of San Francisco From the Perspective of International Peace Movements in Early Twentieth-Century America

The leaders of the Meiji Restoration believed in their master, Yoshida Shoin （吉田松陰）, who claimed that in order for the islands of Japan not to be a colony of the powerful Western states, Japan had to conquer nearby countries. This led to Japan’s invasion of the Ryukyu Islands, Taiwan, Korea, and Manchuria, which ultimately led to the Manchurian Incident of 1931, the Sino-Japanese War, and the Pacific War. Surprisingly, the subject and the timing of each and every one of these acts of war were in the same order of Yoshida Shoin’s proposal on preoccupancy. The Sino-Japanese war of 1894 was romanticized as clearing the barbaric culture by civilization, and the Russo-Japanese war of 1904 was romanticized as the realization of Eastern Peace. However, Japanese policies of aggressions were first deemed illegal by international law during the 1931 Manchurian Incident by the investigations of the League of Nations. The Japanese Empire received the recommendation by the League of Nations to restore to original state, but declined and exited from the League of Nations. Following their exit, they started the Sino-Japanese War and the Pacific War and eventually lost in 1945. The goal of the San Francisco Peace Treaty of 1951 was to punish Japan’s aggressions. However, as the Cold War between the East and the West started to arise in 1948, the punishment was eased, and their punishment for the aggressions on the Ryukyu Islands, Taiwan, and Korea was nearly unasked for. This paper examines the issues of the San Francisco Peace Treaty in the views of the international law of the League of Nations, established by Manley O. Hudson of Harvard University and others in U.S. academia and judiciary.

Thermohaline finestructure observed near the northern Philippine coast

Using hydrographic measurements from three recent surveys in the western tropical Pacific, this study revealed the existence and general features of thermohaline finestructure near the northem Philippine coast. Pronounced finestructttres were detected in the layers of the North Pacific Tropical Water （NPTW） and the North Pacific Intermediate Water （NPIW） during all three cruises and shown to be mainly thermohaline intrusions. Characteristics of the intrusions were further investigated with spiciness curvature and salinity anomaly methods. The vertical scale of the intrusions was 20-50 m and 50-100 m in the NPTW and NPIW layers, respectively. Within the NPTW layer, the Turner angle distribution and correlation between salinity and density anomalies suggested that diffusive convection between surface fresh water and subsurface saline water played an important role in the development and maintenance of the intrusions. In addition, connection between thermohaline finestructure and larger-scale oceanic processes was explored using historical hydrographic data. The results reveal that the salinity field and the distribution of the intrusions in this region were largely determined by mesoscale eddies. As a result of eddy stirring, both isopycnal and diapycnal temperature/salinity gradients were strengthened, which gave rise to the development of thermohaline intrusions. The intrusions acted to enhance heat and salt fluxes and resulted in the mixing of water masses being more efficient. By linking mesoscale eddy stirring to micro-scale diffusion, thermohaline finestructure plays a vital role in the ocean energy cascade and water mass conversion in the northern Philippine Sea.
