Historical early warning of cold wave yellow early warning signal

1. Jiangsu Province issued a yellow warning signal for cold wave.

Jiangsu Meteorological Observatory upgraded the blue warning of cold wave to the yellow warning signal of cold wave, and it is predicted that the minimum temperature in Nanjing and other cities will drop by more than 10℃. The wind in Nanjing is gradually weakening today, but it will be colder today and tomorrow. I hope the public will pay attention to keep warm. It is reported that this is the first time that Nanjing has released this signal since the promulgation and revision of the cold wave standard in 2007. According to experts from Jiangsu Meteorological Observatory, strong cold air has begun to affect Jiangsu Province. It is estimated that in the next 24 hours, the minimum temperature in Lianyungang, Suqian, Huai 'an, Yancheng, Taizhou, Yangzhou, Nantong, Changzhou, Nanjing, Suzhou, Wuxi and Zhenjiang will drop by more than 10℃, and the minimum temperature in Xuzhou will drop by 7 ~ 8℃. Minimum temperature on 22nd ~ 23rd: Huaibei area. When the cold air is affected, it will be accompanied by northerly winds of land gusts of 5-6, rivers and lakes gusts of 7, Jiangsu coastal gusts of 8-9 and 10. Meteorologists reminded that it is necessary to add clothes to keep warm and take care of the elderly, the weak and the sick. In Nanjing, a strong wind blew all day yesterday, but it will converge today, but it is still about level 4, and the minimum temperature will reach -7℃ today and tomorrow. According to experts from the Provincial Meteorological Observatory, unlike the last cold wave, the lowest temperature during the day is only 2-3℃ after the cold wave, so people should feel much colder.

2. Qinghai Province issued a yellow warning signal for cold wave.

On February 3, 65438, a cold current suddenly struck, which caught many citizens off guard. Yesterday afternoon, the number of patients in hospitals in Xining increased significantly. Relevant experts remind that persistent cold current and cold air are most likely to induce respiratory diseases and cardiovascular and cerebrovascular diseases. 65438+8: 00 on February 3rd 15 Provincial Meteorological Observatory issued a yellow warning signal for cold wave. It is predicted that in the next 24 hours, the daily average temperature in Xining, Haidong, Haibei, Haixi, Hainan and Huangnan will drop by more than 4 degrees Celsius and may continue. According to the person in charge of the weather department of the Meteorological Observatory, there will be obvious gale and cooling weather in most areas today. From the night of the 3rd to the day of the 4th, there will be snow showers in the northern part of Xining, the northeastern part of the sea and the eastern part of Haibei, and the daily average temperature in Xining, Haidong, Haibei, Haixi, Hainan and Huangnan will drop by 3 to 5 degrees Celsius.

3. The Central Meteorological Observatory issued a cold wave yellow warning at 20 10+ 10 on June 8.

Lin Jian, the first forecaster of the Central Meteorological Observatory, said: In the next few days, most areas of China, including northern and eastern Xinjiang, eastern northwest, northeastern China, most of Inner Mongolia and most of central and eastern China, will be affected by this cold wave. The cooling range in most areas is 8- 12℃, and the cooling range in northern Xinjiang, most of Inner Mongolia and parts of Northeast China may be larger, which is 10- 16℃, and in some areas it is about 16-20℃. The strong wind range is basically the same as that released last time.

Lin Jian introduced that the strong cold air caused a large cooling range and the low temperature lasted for a long time, which would cause a wide range of rain and snow. Before the cold wave strikes, it will also cause foggy weather in the central and eastern regions.

Lin Jian: Two days before the cold wave came, there was still foggy weather in the central and eastern regions, especially tomorrow morning, which had a serious impact on traffic. The foggy weather is mainly in central and southern North China, Jianghuai, Huanghuai, Jiangnan and northern South China, including the eastern Sichuan Basin. There will be fog with visibility below 500 meters in Chongqing.

The strong wind brought by the cold wave will aggravate the ice situation in the northern part of the Yellow Sea and Bohai Sea. The National Marine Environmental Forecasting Center predicts that the maximum floating ice in Liaodong Bay will be expanded to 65-75 nautical miles from June 65438+1October 65438+September 23, with the maximum ice thickness of 40 cm.
