据气象部门最新预报，河南省或将再次迎来冻雨天气。冻雨是一种特殊的降水现象，当高空温度高于0℃、中层大气存在低于0℃的冷层、而近地面气温又略高于0℃时，雨滴在下落过程中会保持液态，一旦接触地面或物体表面（如道路、电线、树木等）即迅速冻结成冰，形成‘雨凇’。这种天气极易导致道路结冰、交通受阻、电力线路覆冰甚至中断，对公众出行和基础设施安全构成严重威胁。此次冻雨过程主要受强冷空气与暖湿气流交汇影响，预计将在河南中南部地区出现，持续时间可能达12至24小时。气象专家提醒，公众应密切关注天气预警信息，尽量减少外出；驾车人员需特别注意路面湿滑和能见度降低；相关部门应提前做好除冰、防滑及应急抢修准备，防范次生灾害发生。冻雨虽不常见，但其破坏力不容小觑。近年来，随着极端天气事件频发，提升城市韧性与应急响应能力显得尤为重要。河南作为中部交通枢纽，更需加强气象监测与联动机制，保障人民群众生命财产安全。
According to the latest forecast from meteorological authorities, Henan Province may experience freezing rain again. Freezing rain is a rare but hazardous weather phenomenon that occurs when raindrops fall through a layer of subfreezing air near the surface and remain liquid until they contact surfaces such as roads, power lines, or trees—where they instantly freeze into a glaze of ice, known as ‘glaze ice’ or ‘rime.’ This can lead to extremely slippery roads, traffic disruptions, and ice accumulation on power infrastructure, posing serious risks to public safety and essential services.This upcoming event is driven by the collision of a strong cold front with warm, moist air masses, and is expected to affect central and southern Henan for approximately 12 to 24 hours. Experts urge residents to stay updated on weather alerts, avoid unnecessary travel, and exercise extreme caution if driving due to reduced visibility and icy conditions. Local authorities are advised to activate de-icing protocols, deploy anti-skid measures, and prepare emergency response teams to mitigate secondary impacts.Although infrequent, freezing rain can cause significant damage. As extreme weather becomes more common, enhancing urban resilience and emergency preparedness is critical. Given Henan’s role as a major transportation hub in central China, strengthening real-time weather monitoring and interdepartmental coordination is essential to safeguard lives and property.
