The lowest temperature in Guangxi fell to 9!Frost, frost, and low temperature warnings all at once

Frozen!Hands!Frozen!Feet!

It's really cold these days.

The morning was bitterly cold.

Motorcyclist travelers.

They all said that their faces were numb from the cold.

The meteorological department predicts.

Under the influence of cold air

Guangxi will remain sunny and cold in the next three days

Sunny to partly cloudy over the region.

There is a large temperature difference between morning and evening.

December 16-22.

The Guangxi Meteorological Observatory has been released for 7 consecutive days.

Yellow alert for freezing, blue alert for low temperature.

Temperature-wise

The minimum temperature in Guangxi will drop even more.

The minimum temperature remains low.

continues to be "frozen" in single digits.

Lowest temperature on the 22nd

Alpine mountains as low as -9 -2

Guibei is also as low as -1 4

The lowest temperature in southern Guizhou is only 4 7

The next few days. The sun is still shining during the day**.

It is suitable for washing and drying food.

However, the temperature difference between day and night has increased.

Everyone should pay attention to cold protection and keep warm.

said that the warmest year is good, why is it so cold when the cold wave comes?

This autumn's national average temperature is the highest in history for the same period in history** The results also show that the temperature in most parts of this winter is close to or above average. No matter how you look at it, it contradicts the recent cold wave, what is the reason for this?

First of all,When we talk about a year or month being warmer, we don't determine whether the temperature is warmer than a single weather event, but whether the average temperature over the entire period of time is significantly higher or lower than that of the same period in history. For example, from November 3 to 7 this autumn, there was a cold wave weather process in most parts of China, and the temperature during this period fell off a cliff, which was much lower than the same period in history, but if the average temperature of the whole autumn was calculated and found to be the highest since 1961, it was the "warmest autumn".

Doesn't it mean that global warming is coming?Why is the cold air still so strong in autumn and winter?

There is a huge temperature difference between the equator and the polar regions, and this difference has caused a strong westerly wind to form around the polar regions around the polar regions, which is called the westerly jet stream. The westerly jet stream acts like a "fence" that restricts the cold air from the polar regions. The stable polar vortex is confined to the Arctic region by a strong westerly jet, which is warming 2-3 times faster than the global rate in the context of global warming. As the Arctic warms and the temperature difference between the Arctic and the mid- and low-latitude latitudes weakens, it is difficult to maintain a strong westerly jet, and the cold air in the polar vortex becomes "restless" and more likely to move south. The cold air from the Arctic is much cooler than in the middle and low latitudes where we live, and the repeated cold waves make us feel "cold and cold".

According to the statistical analysis of historical data, the winter temperature in China is generally warm under the background of El Niño, but the periodic cold air activities are more frequent, that is to say, the fluctuations of cold and warm are more obvious.

But,The intensity of the cold air process is not only affected by El Niño, but also has a lot to do with the disturbance of the Arctic vortex and the westerly wind belt in the middle and high latitudes. Since mid-December this year, the Arctic vortex** has been bicentric, located over Greenland and Siberia. With the violent distortion of the westerly wind belt over Eurasia, the Siberian high has strengthened abnormally, and most areas of China have changed from the prevailing southerly wind to the northerly wind, and the cold air has moved southward, resulting in a sharp drop in temperature.

On the other hand, the El Niño-induced anomalous anticyclone in the Philippines transported tropical water vapor to mainland China, so the cold wave process from the middle and high latitudes combined with the abundant water vapor conditions from the low latitudes led to a large range of snowfall in the central and eastern parts of China. In addition, the increase in albedo in clear skies caused by snow on the ground also made the temperature recovery slower in the later period.
