Sea surface temperature east of Australia： A predictor of tropical cyclone frequency over the western North Pacific？

The relationship between sea surface temperature (SST) east of Australia and tropical cyclone frequency over the western North Pacific (WNPTCF) is analyzed by use of observation data.The WNPTCF from June to October is correlated negatively to spring SST east of Australia.When the spring SST is in the positive phase,a cyclonic circulation anomaly in the upper troposphere and an anticyclonic circulation anomaly in the lower troposphere prevail over the western North Pacific from June to October,concurrent with an anomalous atmospheric subsidence and an enlarged vertical zonal wind shear.These conditions are unfavorable for tropical cyclone genesis,and thus WNPTCF decreases.The negative phase of the spring SST east of Australia leads to more tropical cyclones over the western North Pacific.The spring SST east of Australia may give rise to simultaneous change in tropical atmospheric circulation via the teleconnection wave train,and then subsequently affect atmospheric circulation variation over the western North Pacific.     

北羌塘拗陷巴贡组致密砂岩储层特征及控制因素

北羌塘拗陷的上三叠统巴贡组碎屑岩是羌塘盆地的储层重点层系,分析沉积、成岩作用对巴贡组碎屑岩储层物性的影响机制,可以为下步勘探工作提供地质依据.研究表明,巴贡组砂岩总体的成分成熟度和结构成熟度中等偏低,溶蚀孔隙是主要的孔隙类型,孔隙结构表现为分选差、喉道细和连通差.沉积因素是控制优质储层的主要因素,形成于分流河道微相的砂...     

豫北地区高校教师体育健身活动的现状与对策

采用问卷调查等方法,对豫北地区14所高等院校的教师进行了体育健身活动现状的调查.结果显示,豫北地区高校教师参与体育锻炼的热情较高,但是缺乏对国家体育政策的了解,“体育人口”的比例低于全国平均水平,体育消费状况处于全国中等水平.同时,对调查结果进行了分析,并提出了合理化对策.     

湖北省大冶市铜山口铜矿区藓类植物初步研究

铜山口铜矿属于长江中下游最典型的露天开采的中型铜矿之一,为矽卡岩斑岩复合型矿床。2004年7月,在该区进行藓类植物标本的野外采集,经初步鉴定,铜山口铜矿区藓类植物有7科20属29种。丛藓科和真藓科植物为主体,土生或碎石土生种类多、石生种类较少、树生种类罕见,植物区系地理成分较复杂;生活型有矮丛集型(79.3%)、交织型(13.8%)和高丛集型(6.9%)3种。

Radiolarians from the British North‐Polar Expedition (1875–1876): re‐examination of the H. B. Brady (1878) collection

The earliest report on radiolarians from the Arctic Ocean (north of the Arctic Circle) was provided by H. B. Brady (1878 Brady, H. B. 1878. On the reticularian and radiolarian Rhizopoda (Foraminifera and Polycystina) of the North‐Polar Expedition of 1875–76.. Annals and Magazine of Natural History, Series 5, 1: 425–440. [Taylor & Francis Online] , [Google Scholar]). He documented the occurrences of 10 genera from soundings in northern Baffin Bay and north of Greenland, but he did not illustrate any specimens in his report. We have re‐examined Brady's original slide collection, housed at the Natural History Museum, London (NHM), in order to refine his radiolarian identifications to species level. We have identified 11 radiolarian taxa in his slides, but some are definitely more characteristic of tropical oceans rather than high northern latitudes. We conclude that this is most likely due to sample contamination or misidentification of samples. Therefore, the actual occurrence of tropically affiliated radiolarians recorded from the Arctic is uncertain and should be regarded with suspicion.
