2010年4月8日16时至9日10时,霍州市气象局自动站出现故障,监控软件无法正常显示各气象要素实时数据,通过认真分析查找原因,逐步排查故障,最终使问题得以圆满解决。本文对该次故障现象与分析处理过程进行了总结。     

影响靖宇地区温带气旋的统计分析

核电站因它不排放如二氧化碳这样的温室气体,核电对降低能源部门的碳密集作出了贡献,因此愈益受到人们的重视.在对核电站地区的天气、气候环境进行分析的基础上,对影响靖宇核电站地区的温带气旋作了研究.结果表明:1949-2007年期间影响靖宇地区的温带气旋计111个;受温带气旋影响的年数有41年(约2/3).影响靖宇地区且产生强降雨的温带气旋,主要发生在6、7、8月这3个月,并且一半以上出现在7月.影响靖宇地区的温带气旋大部分是东北气旋,占总数的65%;蒙古气旋与华北气旋次之.此外,对造成严重影响的温带气旋的个例也从天气学角度进行了分析.     

城市热岛效应和迁址对赤峰站温度的影响

选取赤峰站和周围3个站1959-2007年年平均气温资料,分析了热岛效应和迁址对赤峰站温度的影响.结果认为,迁址前赤峰站受到了城市热岛效应的影响,热岛效应使得赤峰站平均温度上升了0.7℃.热岛效应强度呈增强的趋势,增温率为0.29℃/10年.迁址后热岛效应消失,升温幅度减小,使得温度变化趋势出现了不连续现象,同时导致了气候变暖突变点的变化.     

海南省自动站气温观测资料评估及气候订正研究

通过海南省16个气象台站2004～2005年自动站与人工并行观测气温资料的对比分析,根据相关标准对海南省自动站气温资料进行了评估.分析表明:海南省自动站与人工观测气温的偏差有日变化和季节差异.产生偏差原因有观测仪器的系统性偏差、观测仪器对气温变化响应的灵敏度、观测时间的差异、太阳辐射对观测仪器的影响等.建立了海口自动站与人工观测气温值之间的经验换算关系,为气候资料的前后连续性使用提供了订正的思路和方法.     

Trace elements in world steam coal and their behaviour in Dutch coal-fired power stations: A review

Trace elements associated with the combustion of coal have received more attention recently, as can be seen from the increasing demands laid down in legislation and permits.Knowledge of the trace element content of coal is essential. Coal used in the Netherlands is imported from all over the world. As a consequence, Dutch power stations are designed to burn a wide range of bituminous coals. The largest share nowadays originates from South Africa, Colombia, and Indonesia, with these three countries accounting for more than 85% of the coal fired in the Netherlands in recent years. The coals, as imported in the Netherlands, have been monitored for their (trace) element content. At present the database contains results of own analyses of about 170 coals, originating from 14 different countries. An important uncertainty was the question of how homogeneous the imported lots are. It appears that the lots as imported from overseas are fairly homogeneous.The behaviour and fate of trace elements in coal-fired power stations has been studied in more than 40 mass balance studies since 1977. More than 50 test series have been completed during co-combustion of biomass and waste materials (up to 40% on mass base) since 1993. It has therefore been possible to establish a relationship between (trace) elements in the fuel and the ash, as well as with emissions into the atmosphere.     

基于微服务架构的地震站网全流程一体化监控平台设计与实现

地震站网全流程一体化监控平台是基于微服务框架,应用数据库、通信、并行计算等传统信息技术,结合新兴的云计算、大数据进行建设的信息服务平台。该平台采用Hadoop分布式处理方案,应用Spring Cloud框架搭建,进行Docker容器封装,以标准RESTful API作为服务接口的微服务架构,实现了各应用服务模块之间的高内聚、低耦合及灵活、可扩展的特性,最终实现对地震台站运行的实时监测、高效运维和一体化管理。

基于对子午链台站地震地磁前兆异常以及地球空间环境变化等研究方向的需求分析,利用网络、大数据、云计算等新技术,结合地震数据专家（DatistEQ）软件,设计子午链台站地磁指数报告自动产出系统。该系统通过低代码、敏捷式开发工作流程,连接不同功能节点,可以实现用户定制化、数据标准化、功能智能化的系统报告产出。通过本地或者云端一键流程化工作,将不同类型的数据发送到科研工作者或其他需求者,简化工作流程,优化数据处理,实现高效率产品产出。     

云南高山峡谷区大型水电站建设开发性移民研究--以漫湾、大朝山电站为例

根据漫湾、大朝山电站移民安置的经验和教训,在云南省高山峡谷区建大型水电站,开发性移民主要应做到：移民安置必须和国民经济与社会发展结合起来,应尽量外迁农业安置：补偿和开发扶持相结合;正确选择移民安置区;合理确定移民的土地,给移民提供生产基地;统一规划建设适用坚固的住房和生产生活配套设施;为移民发展生产提供技术支持;引导和帮助移民进行生态环境保护和建设;建立统一有效的移民管理体制,实现依法移民。     

The Armagh Observatory Meteor Camera Cluster: Overview and Status

Armagh Observatory installed a sky monitoring system consisting of two wide angle (90° × 52°) and one medium angle (52° × 35°) cameras in July 2005. The medium angle camera is part of a double station setup with a similar camera in Bangor, ∼73 km ENE of Armagh. All cameras use UFOCapture to record meteors automatically; software for off-line photometry, astrometry and double station calculations is currently being developed. The specifications of the cameras and cluster configuration are described in detail. 2425 single station meteors (1167, 861 and 806 by the medium-angle and the wide-angle cameras respectively) and 547 double station meteors were recorded during the months July 2005 to Dec 2006. About 212 double station meteors were recorded by more than one camera in the cluster. The effects of weather conditions on camera productivity are discussed. The distribution of single and double station meteor counts observed for the years 2005 and 2006 and calibrated for weather conditions are presented.     

辽宁省积雪对自动气象站观测地气温差的影响

利用1971—2016年辽宁省61个气象站气温、地表温度、积雪日数和积雪深度资料,分析了积雪的保温作用及其对地气温差的影响。结果表明：更换自动站前后地表温度观测方式的差异导致地气温差显著增大,地气温差的增大程度受所在区域积雪日数、积雪深度的影响显著。在积雪期较长、积雪较厚的地区,积雪引起反照率增大,使得雪面温度降低,导致雪气温差减小,而雪的保温作用使得地气温差显著增大。因此,更换自动站前地（雪）气温差与积雪日数呈显著负相关,而更换自动站后地气温差与积雪日数呈显著正相关。各台站之间地气温差随积雪深度的变化系数差异较大,为0.045~0.858 ℃?cm^-1,在年平均积雪日数＜40 d、年平均极端积雪深度＜10 cm的区域,积雪的保温作用随积雪深度增大而显著增大;在年平均积雪日数＞40 d、年平均极端积雪深度＞10 cm的区域,10 cm以下的积雪对土壤保温作用随积雪深度增大显著,当积雪深度＞10 cm后,其保温作用随积雪深度增大的幅度明显减小。
