无人机气象预警喊话 跑出防灾“加速度”_我的网站

A |     (ECNS) -- Three people died after part of a four-story residential building collapsed in Shijiazhuang, north China’s Hebei Province, at 5:42 a.m. Wednesday, according to the city’s Xinhua District Emergency Management Bureau.    A total of four people were trapped in two households, of whom three died in hospital despite emergency treatment, while the other is receiving medical attention and is in stable condition, according to the city's emergency management bureau. Five nearby residents who sought medical attention were examined at a hospital and later discharged.    Search and rescue operations have ended. Preliminary checks suggest a gas leak may have triggered a blast that caused the partial collapse. Residents of the building and nearby homes have been relocated, while the cause of the accident remains under investigation.    (By Intern Yang Hongran, Zhang Dongfang)                    。    5分钟到达 10分钟劝离杭州日报讯“受上游强降雨影响，河道水位随时可能上涨，请河道、溪流边的人员立即撤离，转移到安全地带！”这是临安“一网统飞”无人机正在执行气象预警喊话任务，借助无人机空中巡查与远程喊话，预警信息第一时间覆盖了河道、溪流周边区域，为人员紧急避险、保障群众生命安全争取了宝贵时间。临安地处浙西北山区，地势西北高、东南低，汛期强降雨频繁，小流域山洪风险突出。

B | 临安区气象台工作人员在复盘涉水安全事故时发现，上游暴雨，往往短短半小时就可能引发下游溪水暴涨。

C | 尤其在暴雨间歇期，游客见雨势减弱便返回河道，极易遭遇“回马枪”式强降雨引发的山洪而受困。传统预警发布渠道难以有效覆盖溪河野游点、溯溪段等涉水区域，风险防控难度较大。为破解这一难题，临安区气象局主动提交《关于在暴雨间歇期利用无人机巡护喊话加强涉水安全预警的工作建议》，获区政府相关领导批示肯定。目前，临安区已建成2部X波段雷达、231个区域自动气象站和暴雨短临预报系统，可实现分钟级降雨监测与小时级精细预报。气象实况数据与789路“天目慧眼”监控视频深度融合，能实时锁定高风险区域。依托“一网统飞”低空综合治理平台，全区布设48个自动起降无人机机巢，配备63架行业级无人机，作业覆盖面积达1300平方公里，可即时开展预警喊话，为山区防汛减灾提供有力保障。值得一提的是，无人机气象预警喊话不受地形阻碍，可飞抵风险隐患点，以精准预报预警叠加现场喊话提醒，帮助市民游客第一时间知晓风险、主动避险，打破传统气象预警的时空局限，实现“发现游客—预警喊话—引导劝离”的高效闭环。
