The highest surface temperature in Henan is 70 degrees, and the highest surface temperature in Zhengzhou Station is 60 degrees. What is the cause of the hot weather?

Such a strong high temperature process, and due to the obvious lack of precipitation recently, makes a lot of water in the soil evaporate. The surface soil moisture is obviously reduced, which may be unfavorable to agricultural planting. Many areas have also fallen into meteorological drought. The chief culprit of high temperature is the warm ridge on the westerlies. As can be seen from the above figure, there is a strong warm ridge development in Lake Baikal, but before the west wind warm ridge, the weather-scale subsidence motion is dominant, and the airflow keeps heating up and reducing humidity during the subsidence process.

The day before the west wind warmed the ridge, the weather was fine and there was a long period of sun exposure. Hebei and Henan are just on the dividing line between the second and third steps, in front of Taihang Mountain. The northwest wind from the dry inland sinks further over the mountains and sinks again to increase the temperature, thus making the air mass extremely dry and hot. In turn, it will cause strong high temperature during this period. In addition, under the strong thermal action, a high-pressure system called continental high will appear in the middle troposphere. It is warm and high pressure, and its existence will also make the internal dry and hot downward airflow prevail, which also limits the formation of cloud system. It is not particularly strange that this extreme high temperature occurs under the conditions of long-term sun exposure, sinking and warming of airflow and insufficient precipitation.

I just watered two and a half acres of spring corn at home a few days ago, just for two and a half days. ? Get up and occupy the well, and finish at about 10 in the evening. Cut my neck and arms with the sun and corn bushes during the day. I really ...

I am deeply disgusted with this inefficient irrigation method. However, there is nothing I can do. Rural infrastructure here, can only choose this kind of effort.

Gas inefficient irrigation method, although we have drilled many wells with motors in the fields here in 15, but never.

There was electricity, and it was not until a few years ago that the well was destroyed. The number of wells is not enough, and only wells are far from enough. Pull the hose and move it.

It still takes manpower to move water pipes. ?

It is said that agriculture is the foundation of the country and food is the lifeblood of the country. For such an important matter, the practitioners are so hard and humble. Hammer

They are like an infrastructure fanatic, claiming to be a big agricultural country and self-sufficient. Behind these reputations are hundreds of millions of farmers and migrant workers who can't make ends meet.

Comparative hard work

The Water Resources Department of Henan Province said that there has been a mild drought this year and many measures will be taken to deal with it. However, in the rural front line, the land of capillaries

In fact, what national strength do we feel here?

Personally, I feel that there is no subsidy from farmers 10 yuan, and there is no mention of irrigation facilities or maintenance for farmers.

Build more water conservancy facilities. It all depends on the farmers themselves. ?

Second, do most older farmers complain about this? No, I talked to my mother. I am tired and inefficient when I am pulling the hose to water the ground. My mom doesn't think so. She has been working and irrigating like this since she was a child, and she didn't feel anything wrong. What high temperature subsidies what social security. Never heard of this kind of construction site. If you don't do this, you will farm. Cutting wheat in the field is just as hot, but

Much less than this.

Why can't I accept what others can do?

This kind of mood also made me understand why there was a war.

It is easy to be frugal, but difficult to be frugal.

If I want to do this kind of work when I am old, I would rather work hard than be fifty years old like the previous generation.

I have to live this bloody and sweaty life in the sun in my twenties. ?

There is also an old woman who is accompanied by stinking garbage in the community garbage station every day, soaking in the garbage station every day to pick up garbage, and there is still garbage in that place.

It's a screen master far away. Breathe, lose it and run.

I chatted with my grandmother last winter, only to find out that she collects garbage all day, and her salary is only over 2 yuan, only 800 yuan a year.

When I was in my teens, I was shocked to know.

It's very hot now, and the garbage station stinks even more. The area covered by this abnormal high temperature is very large, not only in Huanghuai, Jianghuai basin, Loess Plateau and most parts of Inner Mongolia.

Compared with previous years, the temperature is also unusually high, but the temperature in Henan and Hebei reached a rare level after this round of high temperature.

The extent of the disaster. ?

Third, the impact of high temperature has obviously nothing to do with red code, rural banks and the property market. I feel very helpless. People usually only speak from their own standpoint. As a farmer, I think the biggest impact of this high temperature is in agriculture. For most people who are not engaged in agriculture, hot weather is nothing more than higher temperature, less going out, staying in air-conditioned rooms for a long time, or getting hotter at work. However, for agriculture, it is time to sow or germinate corn. It doesn't rain for a long time in many places in Henan, and the temperature lasts for 40 degrees a week. If there is no irrigation, our corn will soon die of drought. It is obviously not enough to fill it once. Many people in the village have irrigated it two or three times.

If you don't water the land, you will wait for the harvest. What is the concept of harvest? That's worse than farmers selling a few acres of silage. When farmers sold a few acres of silage, some netizens immediately paid attention to agriculture and criticized it. Some even came forward to denounce it and strictly prohibited it. But at high temperature, no one cares about the need of irrigation in rural areas. How to irrigate? It is still the irrigation method of the last century. Each farmer is responsible for his own land, pumping well water or river water with machines, stretching pipes to the ground, and carrying water pipes for flood irrigation or sprinkler irrigation. Either way, it is extremely labor-intensive and time-consuming. It is difficult to use a high-power pump. The efficiency of most farmers is to irrigate about an acre of land a day. ?

Fourth, there is good news. Two or three days later, the subtropical high moved northward rapidly, which also made the precipitation area in the south move northward rapidly.

In Huanghuai area, the high temperature can be temporarily suppressed. It quickly deepened and developed into a Huanghuai cyclone, which quickly pulled the strong southwest monsoon to North China and formed heavy precipitation. Due to the former

During the period, the ground heat is very strong, and there is more unstable energy in the atmosphere, so the precipitation convection will be more significant, which means more.

It is continuous precipitation with high rainfall intensity. This time, a large number of southwest monsoon will directly impact Taihang Mountain, so Xinxiang and Anyang, which are located on the windward slope of the monsoon, should pay attention.

This rainstorm can be handled according to the norms of the main flood season. Supercomputer predicts that the precipitation in Linzhou city can reach 400 mm within 24 hours, which is comparable to the water intensity of dragon boat in South China.

Of course, the forecast is constantly being adjusted, but we need to pay attention to the sharp turn of drought and flood caused by this cyclone.
