The Yangtze River reverses drought during the flood season , where did this year s flood season go?

This year's flood season is estimated to be impossible to achieve in the summer, at least not until the rainy season in winter.

1. The Yangtze River's "flood season anti-drying" <>

The term seems a bit inappropriate this year, given that summer is also the time when some areas are sowing and maintaining agricultural growth. Summer is the rainy season, which is also what we call the flood season, but this year's flood season has seen the water level of the riverbed drop, and many places have dried up, which is the so-called dry weather. This unusual weather will naturally make us wonder where exactly we are going during the flood season, and at the same time we will think about the specific reasons for this, after all, the dry weather of this season still has a great impact on agricultural production.

Second, this year's flood season is gone, <>

According to the theory of inland internal circulation, if groundwater can evaporate the water vapor above the sky through a relatively normal temperature to form rain clouds, it will eventually rain, completing a perfect internal circulation of water vapor. This internal circulation is of course good for agricultural planting, and it is also conducive to the flood season of the Yangtze River, but the reality is that this year's weather is too hot, and the pressure on groundwater is too great, and there is no way to form cumulonimbus clouds in the sky.

3. This year's flood season may be <> when it will be rainy at the end of the year

According to the current amount of precipitation, the Yangtze River flood season can be said to be far away, not long ago we can just see that Poyang Lake has already grown grass in the lake, and now the water level of many sections of the Yangtze River is much lower than before, this situation must be affected by real weather factors, and the impact of global warming, which is the reality that we must recognize. According to this logic, this year's flood season may only be realized when it is more rainy at the end of the year, but it is undoubtedly not good to have more rain at that time, after all, it is not the time for planting at all.

There seems to be no flood season this year, and the Yangtze River basin has always been rainy, with the flood season generally running from May to October. This year, the water level of the Yangtze River continued to recede after entering the main flood season, and there was a rare phenomenon of "reverse drought during the flood season". This is due to the fact that the Yangtze River basin has significantly less rainfall, less water from the upper reaches of the river, and increased evaporation due to persistent high temperatures.

This year, there were abnormally high temperatures in various places, and the sun was shining during the rainy season, and the long period of high temperature weather caused the water level of the Yangtze River to drop seriously.

This year saw the worst drought on record, and the reason behind this is extreme weather.

caused by frequent occurrences. Among the many extreme climate events, drought develops slowly, lasts for a long time, affects a wide range of areas, and causes greater harm. Due to its long duration and large impact area, especially during the critical period of autumn harvest and autumn planting, the disaster of its formation is particularly serious.

In other words, the greater the intensity and duration of drought stress, the greater the damage to the plants. The occurrence of extreme weather events often triggers agrometeorological disasters, which bring huge losses to agricultural production and food security.

poses a serious threat.

Behind the frequent occurrence of extreme weather is global warming.

consequences. Global warming.

, climate change is manifested not only in changes in climate averages, but also in changes in extreme climate events. In the context of global warming, the global climate has changed to varying degrees, and the frequency and intensity of extreme weather events such as high temperature and heat waves and heavy precipitation have increased. The occurrence and intensity of extreme weather and climate events are also increasing, and the issue of climate change has attracted more and more attention.

Aridification is a global climate and environmental problem in recent years.

An important issue in . In recent decades, with the continuous warming of the global climate, the frequency and intensity of extreme climate events have been on the rise, and the frequency of drought events has also been on the rise. Due to the dual effects of climate change and underlying climate change, the Yangtze River Basin.

In particular, the frequency of drought disasters in the middle and lower reaches of the region is on the rise.

Global warming is inseparable from the destruction of the environment by human beings. On the issue of the ecological environment, the selfishness and short-sightedness of human beings are very obvious, which has further damaged the ecological environment, even to the point of no return. On the other hand, with the rapid development of human social economy, resource and environmental problems are becoming increasingly prominent, which is essential for the sustainable development of human society.

poses a serious threat.

In general, global warming is the trigger for extreme weather, and it is also the main reason for the frequency of extreme weather. Under such circumstances, what we can do is to jointly address the challenge of climate change and jointly safeguard the common home of mankind.

This year's drought is due to the persistence of hot weather, which has led to an increase in people's water consumption. At present, the critical time of rice growth requires more water consumption, and the amount of precipitation has decreased, so our climate is so dry under the high temperature weather.

Because there are still many extreme weather this year, and the temperature in many provinces and areas of my country is relatively high, so it is very dry.

Since June this year, the rainfall in the Taihu Lake basin has been more than 70% less than that of the same period in normal years, especially the rainfall during the plum rainy season, which has led to the low water level of Taihu Lake. At 10 o'clock on July 16, the water level of Taihu Lake was lower than that of the same period in normal years and the lowest in the same period in the past 20 years.

The most important thing is that the subtropical high pressure zone has caused continuous high temperatures, which naturally leads to the evaporation of water in many water systems, but it has not been effectively replenished.

According to news reports, the water level of the Yangtze River is continuing to drop in many places, and due to the impact of high temperature weather, the water level of the river is currently falling and the phenomenon of continuous high temperature weather has occurred in many places. What's even more outrageous is that many large lakes have appeared in the phenomenon of long grass in the lake, which is impossible to see in previous years, at this time in previous years, it is often heard that floods and flood seasons, and this year what I heard is that the whole country has entered the state of large steamers.

This rare phenomenon is also a matter of course, mainly due to the influence of the subtropical high pressure zone, between July and August last year, in fact, this time is often a time when there is more rain, but this year not only did it not rain, but the temperature was much higher than before. Judging from the news that can be seen in the current weather forecast, it is basically hovering above 38 degrees, which means that the Yangtze River is not without a reason for this low water level, we must look at this phenomenon rationally, and at the same time have to carry out a scientific hydration of the surrounding crops, otherwise the consequences will be quite serious.

This year's unusually high temperature weather has led to the phenomenon of drying up and drought in many places, of course the rivers are dry, and the places are of course dry; In many places, you have to rehydrate certain crops at night, because the temperature will be lower at night, and the water will evaporate more slowly. We should also look at this phenomenon rationally, now when individuals travel, they can travel less and travel less, and they must bring good water and pay attention to hydration, otherwise it is really easy to get heat stroke if you are not careful.

It is the hot weather that makes the supply of the river not replenished, so there will be a dry phenomenon, and then we have to deal with this extreme weather.

Because it is predicted that there will be a lot of precipitation in the flood season this year, the water was released in advance, and as a result, the high temperature and less rain led to less precipitation, resulting in a reverse drought in the flood season.

The Yangtze River has entered the main flood season, and there is a rare phenomenon of "reverse dryness in the flood season", which shows that the current environment is not very good, and we should pay attention to environmental protection in time.

This situation is still very rare, and it is because of the local high temperature weather that this situation will occur, and now the relevant departments should make corresponding adjustments to this situation to avoid causing more serious impacts, and may also lead to the subsequent development of the Yangtze River.

This is because this year's summer temperature in the country has created the highest temperature in nearly 100 years. Moreover, there was no rain in the rainy season in most parts of the south this year, which caused the Yangtze River to dry up when it entered the main flood season.

The water level of the Yangtze River is dry during the flood season, creating a record low in the same period, this situation reminds us of this year's high temperature abnormal weather, presumably most of the people in the southern region have experienced abnormal high temperature weather this year, and the surface temperature in some areas can reach 60 70, which has greatly affected the local both animal husbandry and agriculture, because we all know that both the development of animal husbandry and agriculture needs water resources, and the dry weather is undoubtedly a catastrophic blow to these two industries, especially agriculture, A large number of crops were in the field, and it was the harvest season, but the dry weather caused some crops to die of thirst due to the hot weather, which also led to a reduction in the harvest.

Not only that, the manufacturers of animal husbandry, because of the abnormal high temperature weather, so that the breeding of pigs, sheep and cattle have individual heat stroke, such as some pigs in the farm affected by the high temperature weather, there is a large number of heat stroke, which is undoubtedly to increase the cost of breeding, for the future sales, there will definitely be **. Therefore, extreme weather has a great impact on our production and life, and not only that, the whole world has been affected by extreme weather, which undoubtedly has brought a serious blow to the global economic development.

In view of this ever-changing weather, we should pay attention to it, after all, the earth is our home, if we are in an extreme weather for a long time, it will not only affect our life and work, but also affect the survival and development of human beings, especially for our next generation, these extreme weather will cause the health of the next generation to be damaged, affect their healthy development, and hope that in the future our environment will not refresh the historical extremes, especially now that the glaciers are melting, Some of the rocks buried deep under the glacier are gradually exposed, which will accelerate the melting of the glacier and is not conducive to our human survival.

This year, the water level of the Yangtze River continued to recede, and there was a rare phenomenon of reverse dryness during the flood season, hitting a record low in the same period, and some areas in the middle and lower reaches of the river exceeded 25 days; Some areas have not had rain for more than 20 consecutive days. The water level of the main stream of the Yangtze River, Dongting Lake and Poyang Lake decreased by one meter compared with the same period of last year, and the water level of the main stream of the middle and lower reaches of the Yangtze River was significantly lower than that of the same period in history. The water level of the Yangtze River continues to decline, and there is a rare phenomenon of "drought reversal during the flood season".

The water level of the whole Yangtze River channel dropped by an average of one meter. Hankou is the lowest water level for the same period since 1954.

In Nanjing, the weather has been hot since July, and the precipitation is seriously low. The water level of Nanjing Station of the Yangtze River continued to decline, and the lowest tide level was meters, which was the second lowest water level in the same period in history. The water level is low, and the water level of Shuiyang River and Shijiu Lake is the lowest in the same period in history.

As the water level drops, the area of "faces" in some areas of the Nanjing River bank is getting larger and larger, and cracks appear in some places. At the foot of the Purple Mountain, there is less and less water in the Qianhu spillway. Judging by the traces of the mud on the shore, it has fallen a lot.

In some places, rivers have even dried up and stopped flowing. The Yangtze River is a rainwater river, and its flooding is mainly formed by rainfall.

Rainfall has a significant impact on water level changes. Statistics show that this year's rainfall in the upper reaches of the Yangtze River is lower than in the same period of the previous year. The amount of water coming from the upper reaches of the Yangtze River is lower than the average for many years.

Coupled with the rising temperature, there have been continuous high temperatures in Sichuan and Chongqing this year, resulting in a large amount of water evaporation, causing severe drought. The water level of the Yangtze River during the main flood season is low, and Shi Guangqian, deputy director of the Yangtze River Flood Control and Drought Relief Headquarters Office, reminded all localities along the Yangtze River that it is necessary to prevent rain for a long time. He believes that this is the law of the unity of opposites in nature.

In the history of the Yangtze River, there has been a situation of "drought followed by flood" and "flood followed by drought". All localities must still adhere to the flood prevention policy of preferring to be prepared for and not used to ensure the safety of the people's lives and property.

This place may lead to a downturn in the industry, and the weather may be hotter and worse to come, wait and see.

The drought is becoming more and more severe, causing a big water problem and causing problems in many industries to continue to heat up.

In many parts of the Yangtze River, there was a "flood season reversal", and local measures were taken to dredge the river channel and optimize the anchorage to ensure the safety of ships.

The flow of the main trunk of the Yangtze River has decreased by about 51% on average compared with the past five years, the water level of the main trunk of the Yangtze River has dropped by an average of meters, and the water level of many rivers has reached a record low. The scale of waterway maintenance of major rivers such as Xinzhou, Tuqiao, and Jiujiang has also dropped sharply, and the water level of the main trunk of the Yangtze River is close to the dry season of previous years.

The main river of the Yangtze River has completed 5.57 million cubic meters of dredging, completed 9,060 hours of dredging work, the current dredger is mainly shallow, after the shallow bag is removed, the overall water depth can be increased by three meters.

In addition, the waterway department has made a total of 5,014 voyages, with a voyage duration of 10,678 hours, a cruising mileage of 133648 kilometers, a waterway exploration of 9,616 kilometers, and 1,320 navigation beacon adjustments.

In the face of the declining water level of the Yangtze River, the Changhang Bureau quickly organized relevant departments, took a variety of measures, actively responded, strengthened waterway observation, optimized the configuration of navigation beacons, and dispatched a number of dredgers to station key rivers for dredging and maintenance day and night.

Strengthen the supervision of key waters, control the flow of ships in a scientific and orderly manner, strictly prevent ships from sailing beyond draft, and ensure the safe and smooth navigation of the Yangtze River.

The "reverse dryness during the flood season" will further reduce the anchorage area of the Yangtze River waterway, which will adversely affect the anchorage safety of ships.

The Huangshi Maritime Safety Bureau adopts the "tofu block" anchorage mode, divides the anchorage into small anchorage area and large ship anchorage area from top to bottom, and adopts information management methods such as "one library and one map" and electronic cruise to implement "one-to-one" publicity.

At the same time, through a variety of methods, the crew is informed of water changes, weather forecasts, etc., and the knowledge of high temperature fire prevention and drought emergency response is conveyed to the front line.
