The new height of Mount Everest is 8848 86 meters, why did this measurement take several months?

Because Mount Everest gets higher or lower every month, and we have to pursue its accuracy, there is a reason why it takes so long.

Because like Mount Everest, in fact, every measurement has to go through constant adjustments, continuous scientific data, and the weather over there is not very stable. So it's normal to spend a few months. Because of the movement of the earth's crust, the height needs to be checked repeatedly before the final result can be obtained.

The reason why it takes several months to measure the height of Mount Everest is that it is relatively high and difficult to measure, so it took several months to complete the measurement in order to get accurate data.

The latest height of Mount Everest is why it took several months to measure this time, it was because of the bad weather, scientists and some climbers took nearly half a year to measure the height of Mount Everest, because the bad weather caused some difficult tasks, so our scientists are very great. Kudos to our scientists, after all, this is the most accurate measurement that shows that Mount Everest is rising

The new height of Mount Everest is meters, and the reason why it will take several months is due to the weather, and it also needs to go through repeated measurement calculations and a lot of verification calculations to be able to accurately determine the new height of Mount Everest.

This survey took more than several months for our surveying technicians. Mount Everest has thousands of reference points, set at different elevation levels. In many places, there are steep cliffs or year-round snow, which makes it difficult for surveyors.

Thousands of fiducials need to be measured in a closed manner, from the mountain peak to the valley to the mountain, and back and forth hundreds of times in order to measure the accuracy. It took several months to unify all the data into meters.

The new height of Mount Everest is meters, and this measurement took several months, mainly because of the high altitude of Mount Everest and the fact that the plates are always in motion, so the measurement is time-consuming and labor-intensive.

Because it is particularly difficult to measure the height of Mount Everest, and because the weather is relatively cold this year, there are not too many times to enter Mount Everest, and the accuracy of the measurement is relatively slow, so it takes several months.

Because this measurement was carried out jointly by China and Nepal, it required a lot of preparatory work, as well as good communication and coordination. So it took a few months.

This year, the height of Mount Everest was measured in meters, and because of the weather, it took several months for the staff to spend a lot of manpower and material resources to obtain a new height of Mount Everest.

The reason why this measurement took several months was because of the bad weather, and the scientists and some climbers spent nearly half a year to measure the height of Mount Everest, and it took a long time to climb Mount Everest.

Because the height of Mount Everest is not ordinarily high. Therefore, it takes a certain amount of time to get an accurate measurement data, so it will take several months.

It is normal for the way to climb to measure, and in this way, it will be very slow and take several months. To climb Mount Everest first, and then add a lot of precise and precise calculations. High-tech instruments. It can accurately measure the height of Mount Everest.

Oh, it's Mount Everest, the latest height meters, this measurement is the good time, in fact, it's basically more than a month, it's almost the same, if you have this thing to measure, it's getting faster and faster, and now it's all through some of that mechanical equipment, and there are some scientific and technological developments, and the measurement data is more stable than before, and the measurement data is still 8848 points than before.

In general, when measuring the height of mountains, the average sea level is used as a reference. Prior to this, China used the mean sea level of the Yellow Sea as the height benchmark, while Nepal used the mean sea level of the Bay of Bengal as the height benchmark. Due to the different altitude datums of the two countries, after discussion, China and Nepal finally decided to use the global altitude datum for measurement and calculation.

The global altitude datum is an altitude datum based on the global sea level, issued by relevant international organizations, and is authoritative," Dang Yamin, a researcher at the Chinese Academy of Surveying and Mapping, told Xinhua News Agency. ”

In addition to the altitude benchmark, whether the snow at the summit is included in the measurement is also an issue that needs to be negotiated and resolved during the cooperation between China and Nepal. The results of this measurement are based on the high elevation of the snow surface of the summit of Mount Everest, which is based on the global altitude benchmark. As for why the elevation of the snow surface at the summit is measured rather than the elevation of the rock face, Dang Yamin explained:

First, the elevation measurement of Mount Everest in China and Nepal is the first direct measurement of the snow surface, and the elevation value of the snow surface has higher accuracy; The second is that for human mountaineering activities, they are all climbing to the height of the snow surface, which is more symbolic. ”

For this survey, the surveyors of both China and Nepal have paid a lot. Nepal's chief surveyor, Khimlal Gautam, lost his toe due to frostbite while installing measuring equipment at the summit last year; In order to collect more data, Chinese surveyors stayed at the summit for 150 minutes, setting a new record for the length of time a Chinese person stayed at the summit of Mount Everest.

The new measurement of Mount Everest's height took six months. This measurement has been reached. Precise edge line this number. It has taken a lot of human and financial resources, and it has reached new heights.

The best measurement of Mount Everest is actually in May. The measurement of Mount Everest is very difficult. The most important thing is to look at the weather to decide. It's no surprise that it took months.

Why did the new height of Mount Everest take several months? It's because it's to get accurate data. It must be done manually.

Accurate measurements, so that it is easier to observe the changes in our planet. And it must be climbed by hand so that it can be recognized by the world. The environment of Mount Everest is very harsh, so you have to go through countless climbs to climb Mount Everest.

to be able to get good results.

The latest altitude measurement of Mount Everest also has some basis for testing according to some different directions and different methods, and it has been several months, and it is said that there are about two or three months of some time to be drunk, and some specific methods to test.

The measurement of Mount Everest requires a lot of manpower and material resources, and at the same time, there is only a short window period to go to Mount Everest, in order to measure the accuracy of the data, it is necessary to use high-tech equipment, so it is okay to be accurate for a long time.

The measurement of Mount Everest took three or four months because it was too high and because of the weather. There are a lot of things that go through the measurement for various reasons, so it can be very slow. It's also a very powerful and hopeful thing.

This year, the height of Mount Everest was measured in meters, doesn't it mean that global warming has not fallen, but it has risen, because the surveyors have to climb to the summit in person, so due to the weather, it took several months, and the staff spent a lot of manpower and material resources to achieve a measurement of the new height of Mount Everest.

The height of Mount Everest is meters, and the reason why this measurement took several months is because Mount Everest is so high and the terrain is steep and difficult to climb, so it takes a lot of manpower and material resources. There are also weather irregularities that affect climbing and measurement.

The reason why it takes several months to measure Mount Everest is because it is really too high, and it takes a lot of manpower and material resources to measure it through general measurement methods, so it is very normal to take a long time.

China's Mount Everest survey team and related units have also developed a lot of special data processing software for this measurement, a large number of data are summarized and processed, the time spent on data processing alone is about 10 months, and the measurement has been more than 6 months since the end of the measurement, and the measurement results were originally scheduled to be released three months after the end of the measurement, but I did not expect it to last 6 months, and the time consumption is mainly used in data processing and comparison.

The height of Mount Everest is meters, doesn't it mean that global warming has not fallen but risen, because the surveyors have to climb to the summit in person, so due to the weather, it took several months, and the staff spent a lot of manpower and material resources to obtain a measurement of the new height of Mount Everest.

Mount EverestThe height is meters.

Before 2005, and now Nepal.

The high degree of Mount Everest recognized by many countries is still meters, and this data is measured in China in 1975, including Mount Everest.

The thickness of the ice sheet above the rock face on top, which is not included in the numerical meters used in our country today.

Climate

The climate of the Mount Everest region and its nearby peaks is complex and changeable, and even within a single day, it is often unpredictable. Generally speaking, the rainy season is from early June to mid-September every year, and the strong southeast monsoon causes frequent heavy rains, clouds and mist, and ice and snow are raging. From mid-November to mid-February of the following year, due to the strong northwest cold snap, the minimum temperature can reach -50, and the average temperature is around -30.

The maximum wind speed can reach 90 meters per second. From the beginning of March to the end of May, when the monsoon season transitions to the rainy season, and from the beginning of September to the end of October, when the rainy season transitions to the rainy season, autumn weather is likely to be better.

The height of Mount Everest has been rising, and in 2021, using Beidou to accurately measure, the latest height of Mount Everest is meters.

The original height of Mount Everest was about 8,848 meters, and the height of the rock face measured by the State Bureau of Surveying and Mapping of China in 2005 was meters, which is not only affected by different measurement standards, but also affected by the geological environment in which Mount Everest is located. Mount Everest is the highest mountain in the world, and there is also a lot of ice on the rock structure, so there are two heights of Mount Everest, one is the height of the ice and the other is the height of the rock face. The thickness of ice and snow has a certain impact on the climate, and the height of the rock face is mainly affected by geological changes, so the height of the rock face should be relatively accurate, and the change with time is not very large, mainly affected by the geological activities of the Himalayas.

In the early days, the height of the ice was used, and the height of the snow cover (total height) used in Nepal and other countries was 8848 meters, which is consistent with the measurement value of Mount Everest by Chinese surveyors in 1975. In 2005, China used a combination of triangulation, leveling and GPS artificial satellite measurement to measure the height of meters. Different standards make the height of Mount Everest different, and the Himalayas where Mount Everest is located are also one of the most serious regional geological activities on the earth, and it is also the result of the collision between the Indian plate and the Eurasian continent, which is one of the main forms of continental orogeny, which means that the height of the rock face of Mount Everest will also change in the future, and it is more troublesome to climb Mount Everest again and again, and it is necessary to update the measurement.

The average height of the Himalayas has been slowly rising, and the gap between the Pacific plate and the Eurasian plate is getting smaller and smaller, and the squeezing is getting faster and faster, so the Himalayas are growing faster and faster, not the same height as Mount Everest, but there should be a highest point, the gravity of the earth and the capacity of the rocks; The summit may not reach 10,000 meters, but it is already close to the height of a commercial aircraft.

Different countries also use different standards for the height of Mount Everest, but no matter which standard is adopted, the top ten peaks in the world over 7,000 meters are basically in the Himalayas, and hundreds of millions of years ago, the area where Mount Everest is located is also an ocean, and fossils of paleontolites such as trilobites can also be found on Mount Everest.

Mount Everest is located at the junction of the Eurasian plate and the Indian Ocean plate, and the height of Mount Everest is increasing every year, and there is a certain error in the measurement, so the height of each measurement is different.

Mount Everest is known as the roof of the world, and people from many countries have tried to measure Mount Everest, and the height of Mount Everest also changes with natural weathering conditions.

It's because the sea level is rising, and sometimes it's because the sea is eroding the ground, which causes the basic reference to be lower, not every year.

Mount Everest is located at the junction of the Eurasian Ocean Plate and the Indian Ocean Plate, and the height of Mount Everest is increasing every year, and there is a certain deviation in the measurement, so the height of each measurement is different.
