What is freezing rain? Does it rain below zero?

Freezing rain, also known as rain, commonly known as ice. Meteorology calls it freezing rain, because the rain falling from the air is ice on the ground. We know that generally speaking, the higher the altitude, the lower the temperature, but in freezing rain, the temperature near the ground is lower than that at high altitude, which means that there is an inversion in the air. In this way, when the falling rain hits the surface of an object with a temperature below 0℃, it quickly condenses into ice. Freezing rain is a kind of disastrous weather, which often causes power supply and communication interruption. It is the focus of meteorological service. How is high temperature defined to judge the degree of summer heat? Meteorological stations usually use high temperature days, high temperature duration and extreme maximum temperature to explain. Generally speaking, it is called hot weather when the daily maximum temperature is higher than 35℃, and extremely hot weather when the daily maximum temperature is higher than 38℃. When it is predicted that the maximum temperature will be above 35℃ for three consecutive days in the future, the Meteorological Observatory will issue a high temperature forecast to remind people to pay attention to heatstroke prevention and cooling.
