Extreme climate is spreading, what’s going on?

Recently, according to media reports, since the beginning of summer this year, the climate in many places in our country has experienced strange changes, such as the "May snow" in Chongqing, hail in Beijing in the summer, heavy rain in Yunnan, etc. However, recently, climate changes have Not only has the situation not improved, but it has spread to the whole country.

First, there were once-in-a-century floods in Guilin, Guangxi, Yingde, Guangdong, Fujian and other places, and then rare high temperatures reappeared in Henan and Jinan. Many netizens in Henan said: If the heat continues like this, Henan will be roasted into "Kenan" . But back to the subject, why is the weather so weird this year? Will there be other weather disasters in the second half of the year? Follow ScienceBeast to learn the latest news as soon as possible.

Strange weather occurs frequently, what is happening to the earth?

Before talking about these issues, let us first make a brief summary of the weird climate that has occurred. It is currently known that extreme climates of varying degrees have occurred in many places across the country. As of today, Xinjiang, Inner Mongolia, Henan, Hubei and other provinces are still affected by extreme weather. Tortured by the high temperature climate, the average temperature in many places exceeds 40 degrees Celsius.

In sharp contrast, Kunming in Yunnan, Yingde in Guangdong, and Guilin in Guangxi. After Yunnan experienced heavy rains, the temperature dropped unexpectedly. Yunnan, which used to be like spring all year round, now has many citizens wearing coats. Kunming has the highest temperature The temperature was only 17 degrees Celsius, which was extremely unusual compared to previous years.

What is causing all this?

Guangdong Yingde and Guangxi Guilin are even more "difficult". The two places have just experienced a rare major flood. Many places were severely affected and there were casualties. Among them, the Yingde flood was a rare occurrence in a century. , British and German floods are serious throughout the country, and we don’t know how long it will take to restore past prosperity.

From a macro perspective, this year's extreme climate across the country is actually traceable. These extreme climates follow the trajectory of " floods in the south and drought in the north ". What are the causes of all this? Woolen cloth?

The " atmospheric circulation " anomaly on the earth's surface

From the data returned by my country's meteorological satellite , scientists have learned that in fact, since 2022, the overall situation of atmospheric circulation over my country has not been normal, which has also led to the Summer has already begun for several months, but the cold vortex and westerly belt are still "full of energy" and are ready to unleash the cold air at any time. But what is the connection between atmospheric circulation and my country's extreme climate?

actually explains this issue very well. We can understand atmospheric circulation as a global "air flow operation" phenomenon. Global climate change is closely related to atmospheric circulation, whether it is typhoons, rainfall, cold air, warm currents and all climate phenomena. , are all caused by changes in atmospheric circulation, but why has the atmospheric circulation over my country become so abnormal?

How scary is this year’s “craze”?

experts’ explanation for this is: According to meteorological data reports, a warm air mass is forming to control the temperature in the central region of my country, and it covers a wide area. This warm air mass will bring severe weather to northwest my country, North China, and the Huanghuai area. Sustained high temperatures, for example, take Henan. Since June 21, Henan has entered the central coverage area of ​​the warm air mass. The maximum temperature has exceeded 43 degrees Celsius, and even the cement roads have been "baked" and broken into two parts.

In addition to Henan, Anhui, Hubei, Shaanxi, Jiangsu, Hebei, Xinjiang, Inner Mongolia and other provinces have also issued high temperature warnings. Among them, Henan, Turpan, and central and western Inner Mongolia are the areas hardest hit by high temperatures. It is worth mentioning that Turpan's The surface temperature has exceeded 71 degrees Celsius. Local people said: The heat wave blows over like a knife, which shows how terrible this extreme high temperature is.

What other disasters will happen in the second half of the year?

However, compared with the high temperature phenomena in these areas, the southeast coast of my country is in another situation. Guangdong, Guangxi, Fujian and other places are facing terrible heavy rains at this moment, and the heavy rains have lasted for more than a month. A netizen from Shao Fujian said: He has forgotten what the sun looks like. In the first half of 2022 alone, such a severe climate disaster occurred across the country. However, will other climate disasters occur in our country in the second half of the year?

Climate experts believe that the possibility of this situation is low. First of all, the atmospheric circulation is not fixed and will change with the transformation of global air currents. Secondly, the high temperature phenomenon in Henan and other places has shown a trend of easing. In the next few weeks, the As the subtropical high pressure over Henan shifts, cold air and rain will refill the vacancy. By then, the high temperature in Henan will be lifted, and heavy rains in coastal areas will be easier to deal with.

Summary:

Floods in many places have been brought under control, but what once again makes the people nervous is that as the high temperatures and heavy rains leave, a new round of typhoon disasters has arrived. The first typhoon " Siam " is expected to appear Will it land in the coastal areas of western Guangdong and Guangdong? Will this be a new round of typhoon disaster? And when will this year's extreme weather end? Everyone is welcome to leave a message in the comment area for discussion.
