气象学多媒体讲义-第二十章第二十章气象报告和气象传真图的识读与应用第一节海上天气报告和警报一、海岸电台的播报范围海岸无线电台:例如,我国大陆的大连、上海、广州台,香港台,台湾的基隆、花莲和高雄台等,每天定时用中、英文明码电报向国内外商船转发海上天气报告和警报。
大连台负责播报的海域:渤海、渤海海峡、黄海北部、黄海中部。
上海台负责播报的海域:渤海、渤海海峡、黄海北部、黄海中部、黄海南部、东海北部、东海南部、台湾省北部、台湾海峡、济州、长崎、鹿儿岛、琉球、台湾省东部。
广州台负责播报的海域:台湾海峡、广东东部、广东西部、北部湾、巴士、东沙、西沙、海南岛西南部、华列拉、头顿、中沙、南沙、曾母暗沙。
香港台的预报区域:香港、广东、东沙群岛、台湾海峡、台湾省北部、台湾省东部、琉球群岛、舟山、西沙群岛、巴士海峡、巴林塘海峡、黄岩岛、民都洛、南沙群岛、华烈拉、岘港、北部湾。
基隆、花莲、高雄的预报范围为台湾省近海。
日本东京气象厅JMC天气报告的范围,范围A为一般警报,范围B为紧急警报。
二、天气报告的内容和阅读注意事项1、天气报告的内容各岸台均按统一规定的格式和内容编发报文,完整的报文由10部分组成,通常船舶只抄收前面第一到第三部分内容:第一部分――警报(如大风、风暴、热带气旋、浓雾警报等);第二部分――天气形势摘要(高压、低压、锋、热带气旋等天气系统的位置、强度、移向、移速等);第三部分――海区天气预报(天空状况、天气现象、风力、风向、浪级等)。
四、天气报告的应用阅读天气报告后应明确的两个问题:1)目前船舶所在海域处于何天气系统及该系统的何部位控制。
目前天气状况是该系统控制下的一般天气还是包括地方的缩写,有时则用GMT表示世界时;MMM――月份的缩略形式;JJJJ――年;…――其它说明第三节传真天气图的识读一、地面图1、地面分析图(AS)日本东京JMH台发布的亚洲地面分析图包含以下内容:1)图题第一个AS――图类代号,表地面分析;第二个AS――图区代号,表东亚和西北太平洋区域;JMH――传真台呼号,表示东京一台;第二行――表示图时(世界时);第三行――图类的英文全拼。
气象导航与传真图分析第一章天气预报§1. 天气预报的基本原理❖天气预报(Weather Forecast):包括天气形势预报和气象要素预报两种,天气形势预报是指对高压、低压、槽脊、锋面等天气系统未来的移动、强度变化及生消变化的预报。
❖天气预报的基本方法:天气学方法、动力学方法和统计学方法。
❖天气形势(Synoptic Situation):大范围环流型与不同类别天气系统分布的概貌(高压、低压、锋、热带气旋的位置、强度、移动等)。
❖天气系统:显示大气中天气变化及其分布的独立系统。
如冷高压、锋面气旋、副热带高压和台风等系统。
❖天气形势与天气:天气演变是在一定的天气形势下发生和发展的,天气形势能显示未来一定时间内的天气变化趋势。
因此,天气形势预报是天气预报的基础。
❖天气的变化与天气系统及其空间分布密切相关,不同的天气系统伴随不同的天气。
所以说,天气系统是天气现象的制造者,同时又是天气现象的传播者。
正确认识和使用天气预报❖天气预报只能有相对的准确性,而没有绝对的准确性。
正确认识天气预报才能正确使用天气预报,正确使用天气预报才能趋利避害,确保生产安全。
人们对天气变化进行了严密的监视,利用各种仪器在全球范围内进行定时观测,并从大量的资料中不断发现和总结出了天气变化的许多规律性。
天气变化存在客观规律性,我们掌握了这些客观规律,就可作出准确的天气预报。
然而天气变化过程是极其复杂的,相互作用的过程不计其数,至今最庞大的天气模式比起现实大气的无涯无尽来,还是极为初浅的。
辐射和云之间的相互作用、水汽相变的复杂过程、下垫面不均匀的物理特性,都没有很好地考虑,这就足以使天气预报不能达到绝对准确。
船舶天气预报的着眼点❖了解预报海域的海况、气候条件和环流特点。
掌握该海域海流性质、流向流速和分布特点;熟悉该海域气候和季节环流特点。
如风浪、浓雾以及对船舶有较大影响的天气系统的时空分布等。
❖确定预报海域的影响系统。
根据经验,大致确定未来影响本海域的天气系统。

船舶海洋气象导第二十一章第一节气象导航概述一、气象导航的概念1、定义船舶气象定线( Ship Weather Routi ng )根据大洋气候资料、准确的长期、中期、短期天气和海况预报,结合船舶性能和装载特点,为船舶选择最佳路线,并在航行中利用不断更新的天气和海况预报修正航线,指导航行,以达到在最短的时间内和损失最小的情况下完成航行的航海技术。
气象导航所推荐的航线称为气象航线 ( Weather Routes ),又称为最佳航线 ( OTSR -Optimum Track Ship Routing )。
2、分类——岸上气象导航(简称岸导)――船舶自行气象导航(简称自导)――船岸结合导航岸导――由岸上成立的专门船舶气象导航机构,为船舶提供优选航线和跟踪导航服务。
自导一一船长根据所能得到的气象和海洋资料,结合本船性能和装载情况,经综合分析自行选择最佳路线。
船岸结合导航一一岸导机构为船长提供初始推荐航线和中期天气、海况预报,最后由船长选定航线;或是岸导机构为船长提供第一阶段航线(从进入公海开始至48h 的这段航线),并在航行中不断提供气象、海洋方面的预报资料,以后的航线设计由船长完成。
目前,岸导是实施气象导航的最主要方式。
二、气象航线与气候航线的关系1 、气候航线――根据长期的天气和海况资料分析得出的平均特征即气候资料,结合航海经验,总结分析出与各大洋的季节特征相适应的航线,称为气候航线。
2、气候航线的不足――航行在气候航线上的船舶遇到的实际天气和海况有时与平均状况有很大差别,这时沿气候航线航行就达不到预期的效果,甚至会因意外的灾害性天气造成船、货损以及费时等损失;――按气候资料认为是不适宜航行的海域,在某些时候却会出现利于航行的好天气。
3、气象航线的优势――充分考虑了航线上未来的各种天气过程,使船舶可以及时避开危险航行区域和充分利用有利的天气海况条件。
4、两者的关系――由于气象航线对天气和海况预报时效有较高要求,但目前国际上天气海况的中、短期预报较准确,长期预报的准确率还无法满足10 天以上跨洋航线的要求。
