The weather has changed so much these days that people are caught off guard! A few days ago, I was wearing a short-sleeved T-shirt, and in the blink of an eye, I had to wrap myself in a thick coat. I heard that this is the strongest wave of cold wave since the beginning of autumn this year, and there is more than one wave, three waves in a row! What the hell is going on? Is this winter going to be too early?
The cold wave is menacing, and the northeast is directly winter
In mid-October, a wave of super-cold air suddenly moved south, bringing significant cooling to most of China. The Tohoku region, in particular, jumped directly from autumn to winter. The Daxinganling area first ushered in the first widespread snowfall after the beginning of autumn this year, and then the temperature plummeted.
The temperature in Mohe has plummeted to -16.4°C, and the temperature in Genhe has also reached -14.3°C, which is almost the same as in the middle of winter! What's even more exaggerated is that the automatic weather station in Lengji Village actually monitored the extreme cold data below -25 °C, which is simply a fight with Antarctica! Many people in the Northeast were caught off guard by this sudden cold and sighed that "winter is coming early".
The power of this cold wave doesn't stop there. On October 15, the temperature in parts of eastern and northeastern Inner Mongolia continued to plummet, dropping by 6-10°C, and in some places even exceeding 12°C! This kind of cooling speed and amplitude really makes people call it "too exciting".
The cold wave is approaching step by step, and half of China is shivering
Just when everyone thought the cold wave was over, the second and third waves of cold air followed. On October 18-19, most areas north of the Yangtze River suffered another 6-10°C cooling, and some parts of the northeast even exceeded 12°C. Immediately after the 20th and 22nd, the third wave of strong cold air affected the central Dong region.
These three consecutive waves of cold waves are simply approaching step by step, making half of China shiver. Many netizens ridiculed: "Is this to freeze us into popsicles?" Someone else complained: "I just put away the thick clothes, and I have to turn them out and wear them again." Indeed, this kind of ups and downs in the weather has made people's wardrobes follow the revolution.
However, some meteorological experts point out that this intensity of cooling is not uncommon in autumn. Every year after autumn, there are several obvious cold air processes. It's just that this year came a little earlier, and the intensity is relatively large, which makes people feel particularly obvious.
Cold air is frequent, what is the mystery behind it?
So, why has the cold air come so violently and so frequently this year? Meteorological experts explained that this was mainly due to the southward movement of the Arctic vortex anomaly, coupled with the strong control of the Siberian high pressure, which caused the cold air to push southward in waves.
It is also interesting to note that the Arctic sea ice extent has been decreasing in recent years, which has deprived the polar vortex of its stable barrier. As a result, the cold air that was originally "locked" in the Arctic is more likely to "escape" south, affecting our weather.
So, do you feel like global warming is making us colder? In fact, experts explain, the overall global temperature is still rising, but there may be short-term sharp cooling in some areas. It's like opening the door of a refrigerator and the air conditioning will run out, but the temperature of the whole room will not be lowered.
What does the cold wave do? Will it be cold in winter?
In the face of this cold wave, many people are worried: will this winter be particularly cold? In fact, it is still difficult to conclude on this issue. According to the forecast of the Central Meteorological Observatory, the average temperature in North China, Northeast China and the southeastern part of the Qinghai-Tibet Plateau in the next 10 days may be 1-2°C lower than that of the same period in previous years. But at the same time, temperatures in Shaanxi, Gansu, Ningxia, western Inner Mongolia, most of Jiangnan and southern China may be 1-2°C higher.
So, although this cold wave is menacing, it does not mean that the whole winter will be unusually cold. The weather forecast is still a step-by-step forecast, and it's too early to tell how cold it will be this winter.
However, this cold wave does give us a wake-up call. At the turn of autumn and winter, the weather is unpredictable, so you should still prepare to keep warm in advance. Especially for the elderly and children, they should pay more attention to adding clothes to keep warm and prevent colds.
How can we respond to the impermanence of climate change?
Looking back on this cold wave, one can't help but lament the impermanence of climate change. In previous years, it was always said that the winter was getting warmer and warmer, but this year there was a "cold winter early report". This kind of capricious weather has indeed brought quite a challenge to our lives.
In fact, in the face of climate change, there are still quite a few things that we ordinary people can do. For example, pay attention to the weather forecast at any time and prepare for cold and warmth in advance; Reserve more emergency supplies in case of sudden weather changes; The second is to minimize unnecessary energy consumption and contribute to the mitigation of global warming.
Climate change is a complex issue that requires the concerted efforts of all of society. But as long as each of us pays more attention and prepares, I believe that we can always calmly cope with all kinds of weather changes and survive every winter.
This cold wave came suddenly and went fast. After the temperature rises in a few days, we should start worrying about the "autumn tiger" again, right? Alas, this ghost weather is really unpredictable!
