Many citizens reported that a few days ago, they were still swiping all kinds of rime pictures, but they didn't expect to find that evergreen trees such as camphor trees in the community were lodging in succession, the roads were thick and difficult to eradicate, and the vehicles parked in the open air were also frozen.
There are 32 counties and municipalities in the central and eastern parts of our province that have experienced freezing rain, which has a wide range of effects and is relatively rare in the past 15 years. According to the relevant experts of the Provincial Meteorological Bureau, freezing rain is commonly known as raindrops that quickly cool down when they encounter cold air during the landing process and fall into ice, resulting in open-air objects being frozen instantly.
Freezing rain is the product of the clash between cold and warm air, when the strong cold air moves southward and encounters a warm and humid airflow, the cold air is inserted like a wedge below the warm air, and the temperature near the surface plummets below 0°C, and the moist warm air is lifted and becomes a cloud to cause rain. Its formation process requires a special atmospheric stratification, like sandwich sugar, and the distribution of the atmosphere from top to bottom is a state of "cold-warm-cold".
One of the important causes is the rare superposition of the north and south branch troughs. When the north-south troughs are consistent and superimposed during the eastward movement, a low-pressure trough area is formed in the central and eastern parts of China, allowing the southwest warm and humid airflow to move northward. However, there is no strong enough cold air in the north to resist, resulting in a steady stream of warm and humid airflow, forming heavy snowfall in the colder areas of Henan and freezing rain in the warmer areas of Hubei.
On the 4th, the province's low temperature rain and snow freezing weather prevention work ** scheduling meeting, the provincial meteorological bureau experts introduced, the whole process is from February 1, a wide range of cold air southward to form a cold pad, the middle of the clouds from the Bay of Bengal warm and humid airflow, resulting in the strongest low temperature rain and snow freezing weather, freezing rain mainly appears in the central and eastern parts of the province, the rain and snow phase is more complex, rain freezing rain, ice snow sleet intertwined. From the evening of the 4th to the 5th, the rain and snow will be suspended for a short time, and it will snowfall again in eastern Hubei and other places from the evening of the 5th to the 7th, and the weather in the province will improve by the 8th.
