China News Service, October 2. According to the website of the Central Meteorological Observatory, it is expected that from October 2 to 6, strong cold air will affect most of the central and eastern parts of China, bringing strong winds and strong cooling weather.
The Central Meteorological Observatory issued a cold wave blue warning on the morning of the 2nd, which is also the first cold wave warning in the second half of this year.
Due to the fact that the early temperature in most parts of the central and eastern regions was significantly higher than that of the same period of the year, and since September 30 in the south, a large range of high-temperature weather has occurred and will continue until the 4th. At present, the highest temperature at many stations has exceeded the historical extreme value for the same period; Affected by the strong cold air, many provinces will experience severe cooling.
The specific weather forecast is as follows:
Cooling and minimum temperature forecast: It is expected that from 14:00 on October 2 to 20:00 on the 6th, the temperature in most of the central and eastern regions will generally drop by 8 to 12 °C. In southern Shandong, Jiangsu, Anhui, Hubei, northern Hunan, northern Jiangxi, and northern Zhejiang, the temperature dropped by 12 to 16 °C, and in parts of central Inner Mongolia, eastern Heilongjiang, eastern Jilin, southern Henan, Hubei, central and northern Anhui, and central and northern Jiangsu The cooling rate can reach more than 18 ℃.
On the morning of the 6th to the 7th, the minimum temperature line of 0°C will be located in northern Shanxi, northern Hebei, and northern Liaoning, and the minimum temperature line of 10°C will be located in northeastern Sichuan, northern Hubei, southern Henan, and southern Shandong.
During the period, the daily maximum temperature in provincial capital cities such as Nanjing, Hefei, and Wuhan will drop from 37-39°C on the 2nd to 13-15°C, and the minimum temperature will drop from 26-28°C to 11-13°C.
Strong wind forecast: There will be winds of magnitude 4 to 6 in the Yangtze River basin and its north, and gusts of magnitude 7 to 8 in high-altitude areas and rivers and lakes; there will be strong winds of magnitude 7 to 8 in the Bohai Sea, the Bohai Strait, the Yellow Sea, and the East China Sea. Gusts 9-10.
The strong cold air affects the process: the strong cold air mainly affects Gansu, Ningxia, Inner Mongolia and other places on the 2nd, the area north of the Huaihe River on the 3rd, Jiangnan and other places on the 4th, and southern China on the 5th.
Meteorological experts reminded that the strong cold air process has a wide range of influences and severe cooling, especially in parts of the south where the temperature first increased and then dropped sharply.
In addition, it is also necessary to do a good job of windproof reinforcement of simple facilities and high-altitude structures.
