Will there be a blizzard in Liaoning tomorrow and the day after tomorrow?

It is estimated that there will be heavy rain to heavy rain (50 ~ 150 mm) in most areas of Liaoning Province during the day from July 6 to 7, including Yingkou, Panjin, Liaozhong, Xinmin, Zhuanghe, Tai 'an, Xiuyan, Benxi, Fengcheng, Montenegro and Linghai.

In 2020, it will end in a cold wave covering the north and south of the river. The Central Meteorological Observatory issued the first yellow warning of cold wave this winter, and most parts of the country will usher in the coldest weather this winter.

Air pressure:

The pressure generated by air molecules in this area. Generally speaking, the more air molecules exist in an area, the greater the air pressure in this area. Accordingly, wind is the result of pressure gradient force. Some changes in air pressure are caused by storms, and some are caused by uneven surface heating.

Some are caused by atmospheric molecules being forced to flow from the relatively high pressure area to the low pressure area in a certain horizontal area. Most of the high-pressure and low-pressure belts shown on the weather map only form a mild breeze that accompanies us. However, the pressure difference required to generate the breeze only accounts for 1% of the atmospheric pressure itself.
