简介:用大气的研究(NCEP/NCAR)和在冬季期间聚集的客观地分析的由空至海的热流动(OAFlux)的环境研究/公民中心的国家中心的每月的分析数据,单个向量分解(SVD)分析被进行揭示在在北方太平洋上在500hPa(Z500)加热异例和geopotential高度的自台湾东面的菲律宾海流向日本的暖流水兵之间的联合模式。第一个SVD模式证明当加热异例的北自台湾东面的菲律宾海流向日本的暖流水兵是积极的时,在北方太平洋的中央、西方的节的Z500是反常地低的。由填写气象学的领域异例在积极(或否定)年,这被揭示了当时阿留申群岛之土人低加深(或shallows),在西北弯屈自台湾东面的菲律宾海流向日本的暖流加强的overlying(或变弱)并且导致近表面的空气凉爽(或温暖)。而且,这增加(或减少)向上的热流动异例并且冷却(或温暖)海表面温度(SST)因此。在自台湾东面的菲律宾海流向日本的暖流和它的下游的区域的附近,沿着纬度的空气温度的垂直结构是baroclinic;然而,geopotential高度是相等地barotropic,哪个礼品凉爽的马槽(或温暖的山脉)空间结构。分叉的风和垂直速度被介绍显示出异常带的发行量房间。这些被升起描绘(或下降)在中央诺思太平洋的空气,它向西流动并且向上面的对流层东方,下降(或上升)在自台湾东面的菲律宾海流向日本的暖流并且在北美洲的西方的节,然后加强(或变弱)中间纬度的带的房间(MZC)。
简介:地面气象测报业务软件(OperationalSoftwareforSurfaceMeteorologicalObservation,简写为OSSMO)是为了满足(2003版,即新规范)的需要,针对各类气象站地面气象测报业务工作和各级审核部门的资料处理而编制的一套综合业务应用软件.本软件适用于人工观测和自动站观测方式的各类气象观测站以及各级审核部门对地面气象观测资料模式文件的审核及信息化处理,并充分考虑了与原地面测报软件数据格式的兼容,满足了对原数据格式文件的处理.最新版OSSMO2004软件已能做出机制年报表并生成信息化文件.2004年年报用OSSMO2004制作才符合新规范的要求.
简介:1会议背景2015年4月14—16日,欧洲气象卫星组织(EUMETSAT:EuropeanOrganisationfortheExploitationofMeteorologicalSatellites)及联合极轨卫星系统(JPSS:JointPolarSatelliteSystem)在德国EUMETSAT总部举办了第2届卫星数据处理软件包(CSPP:CommunitySatelliteProcess-ingPackage)及国际MODIS/AIRS处理软件包(IMAPP:InternationalMO-DIS/AIRSProcessingPackage)用户会议,会议讨论了目前国际上的主要极轨气象卫星(SuomiNPP、FY-3及Metop、Terra、Aqua、POES)直收用户的数据接收、处理与应用技术,还讨论了欧洲下一代极轨气象卫星(METOP-SG,2021年发射)的载荷配置及数据直接广播。
