Why are our weather forecasts getting more accurate, and what is helping us?

We know that the scientific civilization in the earth has developed to a very high level, but if such a scientific and technological civilization wants to help human beings explore the universe, there are still many difficulties, and because of this, scientists are also going to this aspect, understanding the universe. But scientists have developed a very good understanding of the interior of the earth itself. For example, many meteorologists are now very good at changing the weather, which helps us with the following tools.

1. People's increasingly abundant scientific meteorological theories. First of all, the first point is that with the passage of time, more and more scientific civilizations have been born, and many scientific theories have been created at the same time, and the introduction of these scientific theories is also an important reason why scientific and technological civilizations can develop in this way. And with the development of human intelligence, and with the help of important books, we can identify many scientific theories, from which we can develop a weather forecast for the interior of the earth.

Therefore, the important reason why people can identify weather forecasts so accurately is precisely because people have made great breakthroughs and developments in scientific theories, so that people can learn more about the causes of climate change and meteorology in the earth. <>

Second, the technology of human scientific testing has changed greatly. Secondly, another reason is that there are many meteorological monitoring stations on the earth, and these meteorological monitoring stations can measure the wind speed in certain areas and the amount of water that can fall from rain clouds in the weather in a certain period of time. Such a monitoring method allows us to help people report such information accurately and in a timely manner.

Third, mankind has made a huge breakthrough in the development of satellites. Finally, in the recent period, the last satellite of China's Beidou satellite has been launched. It is precisely because of the successful launch of this satellite that China's radar satellites can help us monitor climate change in more regions, and can also be reflected in people's mobile phones more accurately and in a timely manner.

Because China's detection technology is becoming more and more advanced, it is science and technology that are helping us to make our climate detection devices more accurate.

I think it's more and more accurate satellite technology that is helping us, and the technology is getting more and more developed, with better requirements and accuracy, so we can achieve such an effect.

In fact, the most important reason for our weather forecasts to become more and more accurate is the progress of science and technology, due to the development of society, our scientific and technological level is getting higher and higher, and we can be more accurate in the weather situation.

The weather forecast is made every day, and what is presented to the audience is the final meteorological product. Previously, it required a theoretical basis of meteorology, meteorological observation, monitoring, and then computer processing, analysis, and judgment to obtain the final daily weather forecast.

There are many factors that affect weather changes, and the situation is complex.

Therefore, it is impossible for weather forecasts to be completely accurate. In general, the shorter the forecast, the more reliable it is; The longer the timeliness, the less reliable it is. At the same time, sometimes the weather is also very local, for example, if it rains in a certain city, it may rain in the north of the city, and the local people think that the forecast is accurate; If there is no rain in the south, residents in the south will think that the forecast is inaccurate.

At present, the accuracy of short-term forecasting in China's cities can generally reach more than 80%, but the accuracy of forecasting will vary under different weather conditions. In times of special need, we can do more detailed, such as hourly forecasting, but we need to invest a lot of manpower and material resources, as well as a lot of resources (for example, during the Beijing Olympics, we provided a very detailed forecast for the Olympic Games), and under normal circumstances, it is difficult to do hourly forecasting. The Meteorological Service is trying to make weather forecasts as accurate as possible.

Science is endless, change is absolute, and immutability is relative.

From bad to good, people are comfortable, and from good to bad, people feel incredible! Fickleness and variability are one of the problems to be solved in meteorology.

However, don't expect that once this problem is solved, everything will be fine, and there will be new problems in meteorology waiting for us to solve! In this way, the cycle is non-stop, repeated research, and can only change with the change of the weather, and extreme weather phenomena will continue to appear, this is the dialectic of things, change is eternal, and change is relative!

The accuracy of weather forecasts is improving.

Although the level of weather forecasting has been greatly improved compared with the past, the accuracy of the forecast is also improving, but it is impossible to be 100% accurate, the weather forecast is the judgment made by the meteorological staff according to some weather conditions mastered, generally speaking, the accuracy of the weather forecast within three days is higher.

Of course, there must be some differences between the temperature felt in real life and the temperature made by the weather forecast, and the urban weather forecast is only an average value for that place, but the temperature felt by the same city in different areas is also different, such as the place where the sun is directly exposed to the high temperature in summer, the surface temperature far exceeds the maximum temperature predicted by the weather forecast, and the real-time temperature is also made by the location of the weather station, and the weather conditions on the mobile phone are also updated at any time according to the forecast made by the meteorological station, so it is for reference only.

In addition, in places with dry climates, the temperature monitored by the weather is not much different from the temperature perceived by people, but in places with humid climates, the temperature perceived by people will be several degrees higher than the temperature monitored by the weather.

Because the weather is inherently fickle, I feel that the forecast is inaccurate. Because climate change is caused by many factors, weather forecasts are not all within control.

Because of the harsh environment, the weather forecast can only determine whether it will fall according to the 24-hour situation, but the harsh environment causes the situation to change frequently. And they don't have the technology to make weather forecasts. Changes in outer space cannot be detected at all times.

Nowadays, the movement of the atmosphere is very complex, meteorological science and technology are not particularly developed, and weather forecasting itself is not 100% accurate.

The accuracy rate has not yet reached 20%.Why is that?

Weather forecast. It belongs to the science of forecasting. From the point of view of scientific laws, science cannot be completely accurate, nor can it be accurate forever. The same goes for weather forecasts.

In the past 30 40 years, the level of weather forecasting in China has been greatly improved. At present, the accuracy of the weather forecast for the next 24 hours is and the accuracy of the maximum and minimum temperature forecasts are respectively.

However, the accuracy of public understanding is different from meteorology.

For example, the rainfall forecast for some parts of Beijing is in western Beijing. Most people in the West will think that it is accurate, but residents in eastern Beijing will think that the forecast is inaccurate, which is a true portrayal of the poem "Sunrise in the East, Rain in the West".

But why can't weather forecasts be absolutely accurate? There are many reasons for this: the atmospheric system is a nonlinear system.

The atmosphere is chaotic, and small fluctuations can also create huge turbulence. It's like MIT.

Professor Lorenz made an image analogy: a small butterfly flapping its wings over Brazil, and a month later it may be in Texas.

Cause a violent storm. This is known as the "butterfly effect".

It is precisely because of the continuous changes in the atmosphere that human beings have not yet fully understood and mastered the laws of atmospheric motion. Surface meteorological stations are widely and unevenly distributed. Thunderstorms, tornadoes.

Some small and medium-sized weather phenomena such as hail often become "fish outside the net". Uncertainty in numerical weather prediction. Numerical weather prediction approximates the evolution of the atmosphere as a set of mathematical equations.

By solving the equation, it is possible to obtain ** for future weather or climatic conditions, and the initial value error and calculation error will be amplified over time. Global climate change.

Increased difficulty in weather forecasting. in a warming climate.

The probability and frequency of extreme weather events are increasing, which requires forecasters to further understand and recognize new weather characteristics and climate change laws, and constantly discover, summarize and supplement new forecasting experience.

Although it is difficult to achieve 100% perfection in forecasting accuracy, with the continuous development of science and technology and the continuous improvement of human understanding, the accuracy of weather forecasting will be closer and closer to perfection.

Weather forecasts can be used in agriculture and the military, or to provide weather forecasts for people to go out and get people to do their job of protection.

Weather forecasting is mainly through some instruments and equipment, collecting a large number of data on air pressure, temperature, wind direction, wind speed, etc., to improve the future weather conditions. The weather is sudden and local, affected by a variety of factors, and the level of science and technology is still limited, so there will always be some errors in weather forecasting. Weather forecasts are accurate for overall trends, but there are errors in some localized areas and at specific times.

With the development of science and technology, people's understanding of nature will be clearer, and the weather forecast will become more and more accurate. The above is mine, I hope you like it.

The reason why I seem accurate is that the monitoring of the meteorological station is more real-time, the instruments and computers used are more advanced, and the technology is more advanced, so it is more and more accurate.

People pay more and more attention to the weather, so the more accurate the weather forecast, the more accurate the weather forecast, the more people can prevent the weather disaster.

People are more and more aware of the weather, and people are paying more and more attention to the weather, so the weather forecast will become more and more accurate.

How does the weather department make weather forecasts? Why are weather forecasts sometimes inaccurate? According to the latest data and statistics of the emergency management department, the flood disaster in southern China caused 10,000 people in Guangxi, Guizhou, Hunan, Sichuan, Jiangxi, 78 people missing, 729,000 emergency evacuations, more than 8,000 people in the room house collapsed, 97,000 injuries of varying degrees, and direct economic losses of 25.7 billion yuan.

Why can't the heavy rain be advanced**, then**there are not many people, which cannot be done at the moment. At the moment, the accuracy is no more than 100, not to mention the flood disaster. So what about the weather forecast?

Why Weather Forecast?

What is the weather forecast? What do you need? We can see the weather forecast for only a few minutes, but there are 5 links: weather observation, meteorological collection, meteorological processing, comprehensive analysis and product version.

Meteorological observation it is the basis of weather forecasting, from the ground to the sea, from the ground to the sea, from the ground to the satellite, from the automatic weather station to the holiday balloon, the meteorological personnel through the global meteorological observation system, all - multi-level observation of changes in the atmosphere and atmospheric movement.

The world's standard meteorological observatories are essential for weather forecasting, weather forecasts at a fixed time and at the same time, rich, accurate, high-quality atmospheric observations. What is the weather forecast? Why Weather Forecast?

What is the Butterfly Effect? Data collection meteorological observations quickly pass through and gather at major weather centers, where high-speed computers process the data to obtain various charts and graphs reflected in the weather for the presenter to analyze. The weather map is one of the important charts, a weather map is a special map in which the location of each city and observatory is filled in, along with the main rivers, lakes and other geographical symbols.

There are also meteorological elements of each observatory, which at the same time reflect the main weather systems in the corresponding geographical location, what are the distribution characteristics of weather phenomena and what is the relationship between them? There are many other charts that are important tools for meteorologists to analyze and **. What is the weather forecast?

Why Weather Forecast? What is the Butterfly Effect? Data processing, forecaster, with a pen, a piece of paper.

Later, with the application of high-performance computers, numerical products became the main reference basis for weather forecasting. Numerical is a large-scale project, which is a product of meteorology and mathematics, physics and computers. The core is to use the high-performance super crawler quantity to numerically solve part of the microcomputer depicting the atmosphere, and finally obtain the quantification of atmospheric motion.

The integrated analyst studies a variety of charts and numerical products, combines information from meteorological satellites, weather radars, and makes weather forecasts in the future. Due to the experience of each ** device, the accumulated knowledge is also different, so in the reporting process, the conclusions have been different, so we must finally discuss the consultation brainstorming process, which is called the weather. The chief indicator analyzes and summarizes and forms a final conclusion.

It is a satellite cloud image from a meteorological satellite to the ground, combined with the analysis of local meteorological data, and the conclusion reached through consultation.

The meteorological department uses the data to monitor the weather, according to the rules, to predict the weather for the next few days, and then make weather forecasts, because the monitoring is done in the previous days, so it is sometimes inaccurate.

The meteorological department has special instruments to monitor the weather. It can be used for weather forecasting. Because there are errors, there are times when it is inaccurate.
