At 16 o'clock on January 31, the Hubei Provincial Meteorological Bureau launched an emergency response to major meteorological disasters (rain, snow and freezing); At 16:04, the Wuhan Meteorological Observatory issued a blue warning signal for cold waves. This weather process has been called "the most complicated Spring Festival weather in China since 2008", what impact will it have on Hubei and Wuhan? On the eve of the arrival of the cold wave in Han, provincial meteorological experts interpreted them one by one.
Gou Aning, senior engineer and chief forecaster of the Wuhan Central Meteorological Observatory, said that under the combined influence of strong cold air and southwest warm and humid airflow, from today (January 31) night to February 6, Hubei will have a cold wave, rain, snow and freezing weather process. This process has the following characteristics: wide impact range, long duration, and complex rain and snow phases. From tonight to February 3, there is a cold wave weather in our province, accompanied by 6 9 gales, the temperature drops by 7 10 on the 1st to 2nd, the temperature drops in the mountains by 10 12, the temperature is lower on the 3rd to the 4th, the highest temperature in most parts of our province is only -2 2 on the 4th, and the lowest temperature appears on the morning of the 5th, -9 -6 in the central and western regions, -10 in the mountainous areas, and -5 -1 in the east. The temperature picked up slightly on the 5th and 7th.
At 16:04, the Wuhan Meteorological Observatory issued a blue warning signal for a cold wave.
The phase of rain and snow in this process is complex, with rain, sleet, freezing rain, ice particles and snow. From the 1st to the 3rd, there was heavy to heavy snowfall in northwest Hubei and western northeast Hubei Province, with localized heavy snowfall. From the 1st to the 4th, there was persistent freezing rain or sleet in central Hubei. The eastern part of Hubei is dominated by moderate to heavy rain, with localized heavy rainfall, accompanied by weak thunder and lightning. During the day on the 4th, the intensity of freezing rain and snow weakened, but the snowfall expanded eastward to the eastern part of Jingzhou, Xiaogan, and the northern part of Huanggang. From the night of the 4th to the day of the 5th, the rain and snow were temporarily suspended. From the night of the 5th to the 6th, there was light to moderate snow in the west and light rain or sleet in the east. The rain and snow process ended on the 8th.
Affected by the cold air, it is expected that from February 1 to 2, the temperature in most parts of the city will drop by 7 9, accompanied by 4 to 5 northerly winds and gusts of 6 to 8. From February 3rd to 5th, the temperature was significantly lower, with a minimum temperature of -5 -2 in the morning of the 5th. Gou Aning said that at present, Wuhan City was dominated by rain 4 days ago, and there may be sleet after 4 days. Due to the northerly development of the warm and humid airflow, the strongest snowfall in our province is in the northwest of Hubei Province, Xiangyang and Shennongjia, which is heavy to heavy snowfall, and the strongest period is 2-3 days. Overall, the intensity of this rain and snow is not the strongest compared with history, but due to the long duration of the impact and the wide range, and during the Spring Festival, the adverse impact is greater. She specifically mentioned freezing rain, a weather phenomenon that occurs because the rain encounters warm air greater than zero degrees during the fall, but the ground temperature is below 0, so the rain freezes during the fall process, forming freezing rain, which can cause the freezing of power lines, trees, roads, etc., hindering traffic safety and crop growth, which is a disastrous weather.
