On the morning of October 9, the cold air that had previously brought blizzard cooling to Northwest Xinjiang in China began to move eastward, and many places in the central and western parts of Inner Mongolia in Ningxia, Gansu, Shaanxi Province, responded to the cooling - on the 24-hour temperature change map at 10:00 a.m. on October 9, there was a general 8-10 degree cooling in many places in western Inner Mongolia, gansu, and the 24-hour cooling amplitude of some stations exceeded 15 degrees, and the cooling was drastic.
With the cooling, the cold wind also whistled out of Yumen Pass, and the monitoring data of the Central Meteorological Observatory showed that today's whistling northwest wind has blown into the central and western parts of Inner Mongolia in Ningxia, Gansu, reaching a level of 8-9 in some areas, and the momentum of the gale is even more ferocious than the South China coast under the influence of Typhoon Lion Mountain. The great cooling and fierce winds announced the strength of this new cold air, and the Inner Mongolia Autonomous Region Meteorological Observatory has hung a cold tide blue warning signal at 09:25 on October 09, pointing out that the minimum temperature in many places in Inner Mongolia will drop by more than 8 degrees within 48 hours, the minimum temperature is less than or equal to 4 degrees, and the average wind on land can reach more than 5 degrees, reminding the local to be prepared.
Of course, this cold air also brings good news - at present, the rainfall in the northern part of China is still continuing, and from the radar map, a radar echo belt extends from the eastern part of the northwest region to the northeast of north China and other places, bringing cold autumn rain in many places. But under the strong pressure of cold air, this will be the last wave of rain in the north in the near future, and then, the dry and cold air mass will prevail, and in addition to the traditional autumn rainy area in western China, more places in the north will usher in a period of sunny and cold autumn time.
For example, in Yuncheng, Shanxi, the forecast of the Central Meteorological Observatory shows that after today's rainfall in Yuncheng, the rainfall will be suspended for a period of time, and even completely clear. For Shanxi and other places where there has been a lot of rain recently, the stop of rainfall is of course good news. This also means that dry and cold winter winds are gradually gaining the upper hand in the north of China, and forcing the wet summer winds to retreat to the south of the Yellow River or even south of the Huai River.
Of course, this cold air also has to go south, under the low pressure attraction of Typhoon Lion Mountain, the next two days, the cold air in the south of China's central and eastern regions will be particularly deep, the supercomputer's prediction, by October 10, 850 hPa in the low and medium altitude level of the strong northerly wind will be directly blown to the south coast of South China, the south will be the north wind, continue to cool. At this time, some southern netizens also complained: I still want summer! The cold dew festival has passed, and the summer this year is indeed over in many parts of our country.
