Timeliness, for example, evaluation of the APP delay time to evaluate the timeliness of dissemination of meteorological early warning signals, the delay time in 15 minutes, scored 100 points in time, deducted 10 points for every 15 minutes, buckle up.
手机天气软件被指不靠谱：暴雨过后才发预警 - 天气,暴雨 - IT资讯
广州最近天气很调皮，不但在去年12月出现冬天少有的回南天、1月降雨打破纪录等“怪咖”，而且还破天荒地下起了雪。在气候越来越失调的时候，许多市民都习惯性地低头刷起了手机，期望及时收到来自气象部门的提醒。气象部门近期对众多预报软件展开了评估，结果发现，这一次“赶考”有许多客户端都挂科了。
随机抽取8款软件评估
“又发暴雨预警！”在汛期开始后，广州的强降雨渐渐多了起来，最近不少市民都在留意自己手机上的各类气象灾害预警信号。记者了解到，相比精确到街道和分钟级别的精细化预报，不少手机客户端之前都没有推送预警信号服务，一些长期使用天气预报客户端的市民发现，许多客户端预报不能够做到百分百准确。记者实际比较后也发现，有的预报与实际天气差别还比较大。而在推出预警服务后，不少软件又出现了短信提醒都已经收到，或者雨点都砸下来了但客户端上还没见踪影等问题。
广东省气象局近期对天气App传播气象预警信号的及时性、完整性和规范性进行了评估。气象部门于2015年6月25日在官方网站发布了《广东省气象局关于开展气象信息服务质量评估的公告》，向社会公告了拟开展气象信息服务评估的事项、对象、依据和方式。随后，在最近随机选取360天气、2345天气王、黄历天气、墨迹天气、停课铃、知趣天气、中国天气通、最美天气8个传播广东省气象预警信号的天气APP作为本期评估对象。在2016年3月22~23日强降水过程中，广州、河源、江门等地分别发布了暴雨黄色预警信号和大雾黄色预警信号，评估就是针对8个APP传播这些气象预警信号的及时性、完整性和规范性展开的。
有的暴雨结束了才发预警
专家告诉记者，就预警信号而言，传播速度非常关键，比如强对流天气中，雷雨大风来得很快，只有及时把预警信号发送出去，才能收到好的防灾效果。在3月23日8时31分广州发布暴雨黄色预警信号时，发布最快的15分钟之内就已经发送出去。而耗时最长的几个则在150分钟后才发布，这时暴雨天气过程都快结束了。
广东省气象局有关人士解释说，气象预警信号是各级政府组织防灾减灾的重要参考，也是公众进行防御自救的有效指引。气象部门鼓励各类传播媒体从承担社会责任的角度出发，积极传播气象预警信号，并努力提升传播质量，做到及时传播，尽可能在15分钟内传播气象预警信号。同时，完整传播，传播气象预警信号要包括预警名称、图标、标准、防御指引、发布单位和发布时间6要素。在规范方面，气象预警信号图标要符合《广东省突发气象灾害预警信号发布规定》附件（2014年修订）规定，发布单位应是×××气象台。气象局表示，各类媒体可以通过登录广东应急气象网注册下载气象信息共享包，及时获取广东省各级气象台权威发布的气象预警信号。
省气象局测评情况
积极作用
总体来说，各评估对象都能较为积极主动地传播气象预警信号，为公众获取气象预警信息提供了方便。
存在问题
传播过程中也存在着一些问题,如传播不够及时，大部分评估对象不能做到在15分钟内传播气象预警信号。
大部分评估对象传播气象预警信号缺少预警标准和防御指引，传播的气象预警信号图标、发布单位也不规范。
部分评估对象没有传播县级气象台发布的气象预警信号，而一些评估对象则没有传播气象台同时发布的多个气象预警信号。
怎么测的
此次评估通过气象预警信号传播及时性、完整性和规范性三方面评价气象预警信号传播质量，采用综合加权评分的评价方法，根据气象预警信号传播的重要性，分别赋予及时性得分、完整性得分和规范性得分三个单项指标40%、20%、40%的权重，计算单次预警信号传播质量得分。
以及时性为例，评估以各APP传播气象预警信号延迟时间评估及时性，延迟时间在15分钟内，及时性得分为100分，每超过15分钟扣10分，扣完为止。
