Since the 19th, freezing rain and cooling weather have occurred in some areas of Gansu and Shaanxi, and traffic has been blocked. Freezing rain collides with objects with a temperature below 0 and freezes instantly, condensing into ice extremely quickly. What impact will freezing rain have on roads, railways, civil aviation and other transportation?
Freezing rain can cause the road surface to freeze and produce glare that affects driving.
Gao Jingjing, Senior Engineer of the Public Meteorological Service Center of the China Meteorological Administration: In terms of highways, freezing rain can easily cause the road surface to freeze, resulting in vehicles sliding and tailgating. In addition, icy roads can also produce glare under strong light, which can reduce the driver's vision, which can also be a potential risk for the driver's safe driving.
Freezing rain can cause trains to slow down or even stop running.
In terms of railways, since most trains are currently powered by electricity, each car will have a device that extends upwards called a pantograph. The pantograph is connected to a catenary with electric high-voltage electricity and transmits electricity to the train. Freezing rain falls on the catenary line and is quickly wrapped into ice, which will cause the locomotive pantograph to take the current poorly, and the current will not meet the requirements of the train, and the train will slow down or even stop running. At the same time, freezing rain will also freeze on the tracks, and the train will take longer and travel more distance when accelerating and braking, making the train travel slower.
Freezing rain can cause ice on airport runways, affecting flight takeoffs and landings.
In terms of aviation, freezing rain will cause the runway of the airport to freeze, make the distance of the aircraft during take-off and landing longer, and even directly cause the aircraft to be unable to take off and land, which will have an impact on the operational safety and efficiency of the flight.
It is recommended that the public pay close attention to the latest weather forecast of the meteorological department in the near future, try to avoid freezing rain areas when traveling, and also pay attention to the dynamic information of railways and aviation in a timely manner, and make travel plans.
