Why is this year hotter than previous years?The high temperature of nearly 47 ° C appeared in Zhongfu because of the greenhouse effect?

The strongest high temperature weather in 61 years? This summer is indeed unusual, and high temperatures are constant in many places. There are many regions of 40 ° C and 50 ° C world. Judging from the highest temperature of this year, the highest is Tocoson, reaching 46.6 ° C! Unbelievable, nearly 47 degrees high temperatures in my country, how do people in this area live!

Is it so hot this summer?

There have also been extreme high -temperature weather in history. In the "Song History" records: In the first year of Jiading, spring is like summer. In the winter of six years, it is thunderous, no ice, and insects are not stinged. In the summer of eight years and May, the big crickets, the grass are dry, all the Quansquan is exhausted, and the water of the water is hundreds of money. In the winter of nine years, there is no snow. In the winter of one or three years, there is no ice and snow. Over the age, spring storms, soil dry springs exhausted.

During the Jiading period of the Southern Song Dynasty, the drought in Jiangsu, Anhui, accompanied the heat. Because it is too hot, "Xingdu has a hundred dollars of water, and the water of Jiang and Huai Cup counts a few money, and the dead are very crowded." What concept? Usually 1 yuan of water rose to 100 yuan, and countless people died because they had no water.

This is not the hottest

In 1601 BC, the North China region suffered a lot of droughts. In "Mandarin · Zhou Yu", it is recorded that Xiyi and Luo died of the summer, and the river was exhausted. This means that the drought was exhausted by Yishui and Luoshui, causing the Xia Dynasty to die, and the dryness of the Yellow River led to the destruction of the Shang Dynasty.

This is not the hottest!

The hottest was Qianlong in the Qing Dynasty, 843, which was the hottest summer in history. Experts from the National Meteorological Administration converted the data recorded by the French leaders at that time. It was discovered that the temperature in Beijing on July 25, 1743 was as high as 44.4 degrees. During July 14-25, 1,1400 people in Beijing were hot. In "Tianjin County Records", it is recorded that May is bitter, soil and rocks are burnt, and the mast is golden. Death.

According to the local county records, the entire North China region has become purgatory, including Tianjin, Hebei, Shanxi and other places. Many poor people walk on the road and suddenly fall to the ground!

Drought is already terrible, and locusts are even more terrible after the drought!

In the spring of 1942-1943, a major drought disaster and locust accident occurred in Henan, which led to most of the crops in the summer and autumn of the year. This time, 3 million of the 10 million people in Henan had starved to death, and 3 million people went out of Tongguan to be exiles. They starved to death, ill, and squeezed the train to the dead and the dead were countless.

Compared with the hot summer in the above history, the temperature is no longer much, it is just hot, and there is no serious drought, causing a large number of crops to reduce production. However, there are really many areas that appear hot weather this year. For example, in June, Henan first broke through the 40 ° C mark, and the temperature of Jiyuan even soared to 74.1 degrees. From the video released by netizens, the cement roads have exploded. Zhejiang and Chongqing were so hot. Not only our domestic heat, the temperature in the United Kingdom has reached 40.3 ° C in many places. It has been tanned to the airport runway, and Portugal has also soared at high temperatures. It has died hundreds of people a week.

Why is it so hot this summer? Is it normal?

This year's high temperature weather is a bit extreme, obviously abnormal, mainly caused by the "atmospheric circulation abnormal". What does that mean? Simply talk!

Usually during the three -volt period of each year, the Jianghuai area will enter the dry period, and the weather is dry and less rainy, but there will be a typhoon and rainstorm in the afternoon. After the North China and the Yellow River Basin areas entered Futian, it was the rainy season. Almost half of the rain throughout the year must be concentrated at this time, which is prone to flood floods. In these areas, Sanfu Tian is usually very hot. If it suddenly feels cool, it may be to come to the typhoon. Therefore, it is better to be hot during this period, which is conducive to the fullness and maturity of the grains, which is helpful for the increase in yield.

Of course, what I said is that under normal circumstances, there are different results if the "atmospheric circulation is abnormal".

Usually the strength of the northern temperature depends on the "high pressure of the mainland", and the temperature in the south depends on the "Western Pacific Vice Pressure". There are many sinking air flows under this high pressure. As a result, the water vapor on the ground cannot rise. To form a cloud, in this way, the heat of the sun can reach the ground unimpededly. In addition, these water vapor that cannot be formed in clouds gather in the air on the surface, making the humidity in the air larger, and at the same time wrapped in high temperature and humidity, not to mention how uncomfortable it is. This year's northern "mainland high voltage" has obviously moved south. In the area superimposed by the "high pressure of the mainland" and "Western Pacific High", it has induced high temperature. At the same time, the cold vortex of the northeast south, suppressing the "Western Pacific Deputy High" moved north, leading to the process of continuous rainfall in Jianghuai, Guangdong, Guangxi, and Fujian Essence

This is nothing? The ancients have long said that in the Sanfu Tian, ​​"drought and rainlord, rainwater and waterlogging, and waterlogging to prevent drought." Therefore, the farm proverbs left by the ancients still have reference value. After all, the ancients have been summarized with naturally with nature for a long time.

However, this year is a bit abnormal. In previous years, it only affected the "Iran's high pressure" in Xinjiang, and also came to the east to pressure. In addition, the continuous "La Nina phenomenon" is also assisting. The so -called "La Nina phenomenon" refers to the west of the surface of the surface of the heat to the west of the Pacific Ocean, and the seawater east rolled up from the bottom of the sea, which is particularly cold. Affected by this, the weather conditions such as "cold winter and hot summer and hot summer and hot summer and hot summer, and typhoon and typhoon. From the continuous high temperature weather in the Sichuan area in July, as high as 40.5 degrees, it is really "uncomfortable"! There are also Hangzhou, Chongqing, Jiangsu, Shanghai, Zhejiang, Suzhou and other places.

It will enter the end tomorrow. In this hot weather, some areas in the south will last at least a week. Fortunately, we now have better disaster prevention methods, irrigation and drainage facilities, which can reduce the impact of drought and floods, so as not to cause greater losses!

For the current high -temperature weather, what do you think of it? Is it normal? Looking forward to your comments!

After the full text, I saw this, and just like it! Thank you for reading.
