The difference between graupel and freezing rain

The difference between graupel and freezing rain is that:

Graupel: Also known as snowball or soft hail, it is solid precipitation composed of white opaque ice particles, which are approximately spherical (sometimes conical) and have a snow-like structure. It tends to bounce back when it hits hard ground, and it is crunchy.

Freezing rain: It is a disastrous weather in early winter or late winter and early spring. It is composed of ice-water mixture and freezes immediately after colliding with objects with a temperature below 0℃. Raindrops below 0℃ can remain supercooled in air with a temperature slightly lower than 0℃, and their appearance is the same as that of ordinary raindrops. When they fall on an object with a temperature below 0℃, they will immediately freeze into a smooth and transparent ice layer, which is called snowball.

Guide to preventing freezing rain

After freezing rain, the power and communication departments should clear the ice on the wires in time, or start the ice melting technology in time. At the airport, it is necessary to clear the accumulated ice on runways and planes in time, install deicing equipment on planes or simply fly around freezing rain areas. For the ice layer on the expressway, it is necessary to melt the ice in time and organize manpower to clear the snow on the road to avoid traffic accidents. In case of an accident, obvious signs should be set at the scene to avoid chain traffic accidents.

At the same time, in freezing rain, people should try to reduce going out. If you go out, you should take measures to prevent cold, keep warm and prevent slippery. Pedestrians should pay special attention to avoid motor vehicles. Motorists should slow down in freezing rain, do not overtake, accelerate sharply, turn sharply or brake suddenly, and install snow chains in time if necessary.
