: Record cold weather paralyzed most parts of the United States. On Tuesday morning (65438+10.2), almost half of Americans woke up below zero, and about1.10.8 billion people were affected by the cold warning. Now, the cold air formed by the bomb cyclone on the east coast of the United States threatens the area from northern Florida to New England. This weather event may make 20 18 one of the worst winters in America, and this is only the first week of 1. Bomb cyclone, also known as explosive cyclone, is usually formed on the water surface, and the decrease of air pressure will make the climate extremely intense. According to the weather forecast, to make matters worse, this storm, which has already plunged the central part of the United States into extreme cold, will also plunge the Atlantic coastline of the United States into a deep frozen state. In the United States, extreme cold weather has caused eight deaths.
The cold New Year's Eve recorded in Times Square in America is-17.
The forecast temperature this year is-1 1, which is the second coldest year in history.
It is reported that eight people have died of low temperature and severe cold.
On the morning of the 3rd, a low pressure will begin to form in eastern Florida, bringing rain and snow to West Jacksonville, Florida and southern Georgia.
On the afternoon of the 4th, the storm system is expected to reach eastern Long Island, Washington, D.C., Philadelphia and eastern new york, where there will be heavy snowfall.
On the morning of the 5th, cold air will appear again in the eastern United States, and Boston may even have a low temperature as low as 0 degrees Fahrenheit (about minus 17.8 degrees Celsius).
Meteorology now calls this weather event Winter Storm Grayson, and indicates that it may bring snowfall (and weather close to snowstorm) to the southeastern part of the United States on Wednesday night (65438+1October 3), and may bring snowstorm weather to the northeast on Wednesday night and Thursday. In addition to the wet winter weather, cold air will make the situation on the east coast of the United States even more miserable. Boston will have its coldest week in a hundred years.
The National Weather Service said. If cold air and heavy snow don't fall on you, windy weather will accompany you. The storm warning is currently in the middle of the Atlantic Ocean, covering 40 states including Ohio, Kentucky, Tennessee and Pennsylvania. Pittsburgh State University and University of Pennsylvania may have a weather of MINUS 20 degrees on Tuesday night, which is before the storm warning.
Maybe MINUS 20 degrees made the American people collapse.

7. Today's weather forecast in new york.
(ECMWF)1975165438+/kloc-0 was formally established on October 4th, and the medium-range numerical weather forecast was officially released on August 6th, 1979. Since then, it has gradually established its leading position in the field of numerical weather forecasting technology in the world, and its products stand out from the competition with other countries in the world, including the United States, which has strong basic scientific and technological strength, and have to bow before the success of Europe.
When Hurricane Sandy hit the east coast of the United States in June 20 12, why the global numerical prediction model in the United States did not perform as well as ECMWF results once again attracted the attention of all walks of life in the United States. RichardRudd, a professor in the Department of Atmospheric, Marine and Space Sciences at the University of Michigan, published an article in the Washington post in March this year, which made a multi-angle analysis on this issue.
In the past 20 years, Luther had the opportunity to work in ECMWF and NOAA successively, and made a detailed comparison between them. He has submitted a special report to the US Office of Science and Technology Policy, and gave some suggestions. Reading Luther's article, it is not new that the numerical weather forecast model in the United States is weak, but it is a common problem in China. But Luther S's analysis is more targeted, comparing the practices of the United States and Europe, and revealing the problem concisely, clearly and convincingly.
The ECMWF numerical weather forecast level exceeds one level.
The development of science and technology oriented to practical application is different from the research of basic theory, and it is necessary to systematically grasp every specific link in application. Teacher Luther emphasized this point from the beginning.
The numerical weather forecast level of ECMWFs is at the top level in the competition of many international models, which is not recent. Since the establishment of the center, the continuous improvement of its forecasting ability has attracted the general attention of colleagues all over the world. Almost all weather forecasting business centers around the world have gradually introduced the numerical forecasting products provided by ECMWF.
Teacher Luther said that as early as 1995, American scientists expressed great concern that the product level of the European center surpassed that of the United States. However, the analysis conclusion at that time was inconsistent with the reality, and it was considered that the advantages of the European Center were only in budget, computer capacity, short-term advantages and visiting scholar programs. At that time, many American scientists crossed Washington State to work in Reading, England (where ECMWF is located). Therefore, it is suggested that the United States adopt a similar plan to prevent the brain drain in Washington from happening again.
Last year, in the discussion caused by the gap between the forecast of Hurricane Sandy and the European center again, magazines and media such as Science, USA Today Weather Channel and Weather Log published articles one after another, and still attributed the main source of the problems in the United States to the shortage of computer resources, apparently failing to find the root cause.
Compared with some similar institutions in the United States, ECMWF is a small department with relatively concentrated objectives and tasks, which is conducive to its effective management of scientific research, business and infrastructure capacity building to meet development needs, and has sufficient autonomy in budget implementation. It is clear that the only goal of all work is to make the best prediction products, and attention should be paid to establishing internal incentive mechanism in management to encourage employees to concentrate on improving the prediction effect. The determination of this goal and mechanism means that we can't just pay attention to one aspect.
In fact, complex detection information processing, computer ability and usage level, numerical model design and research and development; Class d and so on. It must be improved as a whole to form high-quality forecast results, which should also include business operation, monitoring, continuous inspection and evaluation of products, etc.
For a concrete example, in the 1990s, the development of computers faced a shift from the performance of a single chip to parallel computing. ECMWF realized its potential value, invested development funds in advance, and constantly tested and compared two different softwares. When this technological change really happens, everything will come naturally. The United States, on the other hand, lacks the development vision in this respect. For a long time, it only depends on the improvement of CPU operation speed of high-performance computers. Therefore, only in the field of computer technology application, the gap with the United States directly affects the improvement of the final forecast level.
Paying attention to the systematicness and integrity of forecasting technology promotion will affect the concentration of key technologies? In this regard, by comparing the practices of the United States and Europe, we can find different consequences caused by different strategies.
ECMWF first focuses on optimizing a single software module, and then integrates it into the final prediction system according to the standard. We are constantly optimizing, improving, using and relying on this integrated system to avoid the waste of extra resources, whether it is scientific research and development or the final forecast product generation. Because ECMWF adopts this reasonable solution to the basic problems of the model, it is relatively easy to continuously improve and perfect, and it is also conducive to the scientific analysis and evaluation of the improvement results, and the problems in any link can be clearly identified, thus promoting the integration of good scientific research results into the business conveniently and quickly.
Experience of ECMWF numerical weather forecast
In contrast, American business departments always have several independent test systems running at the same time. When the improvement of a certain mode gives satisfactory results, it is not easy to transform it into a formal business system according to business standards. If there are obstacles in some links, all efforts may be wasted.
Comparatively speaking, the European method is more scientific and efficient. Their management principle is to establish a scientific organization system, not just the organization of scientists. This principle makes them pay more attention to the overall effect of development than the independent achievements of some scientists.
Paying attention to the system development of forecasting model does not mean that ECMWF must complete all the links that affect the development of forecasting model. How to balance the rational use of manpower and financial resources? Luther gave an example, which may illustrate the wisdom of Europeans. The weather forecast system usually consists of several main parts. The first step is to obtain observation data, check its accuracy and continuity, provide initial information with quality control for the model, and form an initial forecast field after processing.
Therefore, in the prediction model system, the effective use of observation information is the initial and basic link to make accurate prediction. ECMWF analyzes various situations of forecasting failure and shows that their attribution is often related to the use or exclusion of some observation data. However, in American research projects, the research on data usage is often not paid enough attention. This practical process, which requires strict control of information quality through complex interactive processes, is usually very difficult.
Mr. Luther used to work in data inspection at NASA, and completed an experiment, which proved that some new observation data can be brought into the model to improve some known inherent defects in the prediction. Unfortunately, these valuable observation information and equipment are not owned by the corresponding forecasting institutions, and what Rudd has to do is to verify whether the data obtained from the observation equipment owned by the forecasting institutions have also improved. Such arrangements and requirements obviously lack efficiency and rationality.
In contrast, ECMWF does not have its own observation equipment, but attaches great importance to the application of data. It is willing to continue to invest in this field, trying to obtain data from all over the world, analyzing and testing all kinds of data that may improve the forecast, establishing a very advanced data assimilation system, and paying attention to developing a convenient data control application interface to facilitate the use and evaluation of all kinds of data. In the past ten years, ECMWF has been able to use advanced methods to integrate and absorb various data into forecasting models. These data can come from Europe or any other country, such as the United States, China and Japan. And most of them are detection information of various meteorological satellites.
In the whole weather forecast system, the investment proportion of observation system should be the largest, but ECMWF wisely avoided the expenditure burden in this area and concentrated on the research of data use. In this research and application, it also makes full use of outstanding scientists in the international community and easily integrates their achievements into its own forecasting system.
In terms of effectively absorbing the outstanding achievements of scientists from all over the world, ECMWF has the advantage of providing a convenient working environment and development platform for visiting scholars, so that these scholars can apply their skills and achievements to model development in a short time after visiting, make contributions to the best forecasting system in the world, and improve their careers. Can have such an effect, why not?
In the United States, organizations with similar missions to ECMWF also have gaps in the stability of development and are relatively scattered. This dispersion is cured in the system. American institutions are more willing to support independent researchers who have outstanding performance in basic research, and how to turn these basic research into systematic products with scientific and technological connotation often depends on luck.
In the United States, the budget for infrastructure and system integration is always very tight. Compared with the priority of scientific research institutes, business objectives are always in a lower position, or are considered as by-products of excellent scientific research. Investment in basic strategic capabilities always meets those planning fields with scientific challenges and uncertainties. There are few opportunities to find sources of funds, such as some incentive funds, to encourage some practical projects. Even if some plans are successful, there is no meaningful cross-planning integration, and the improvement of business ability often takes a long time and several years of scientific success.
This involves a very important issue, which is the construction of scientific culture. ECMWF organically combines science with business, aiming at manufacturing application products with solid scientific foundation and capable of standing the test of practice. The establishment of this goal and evaluation criteria has promoted the sustained and stable development of ECMWF. In contrast, in the United States, there is a strict boundary between scientific research and business. Scientists and scientific research managers regard the value of research, especially basic research, as the highest standard, while user-oriented applied research has not been highly praised because it provides the demand for final products and comprehensive research. In this way, researchers are willing to make greater efforts in basic research, and when there are some innovations or breakthroughs, they will begin to change new fields or problems.
Although the numerical weather forecast model in the United States can be continuously and systematically improved under the decentralized scientific and cultural environment, these incomplete improvements have inherent shortcomings in efficiency, and there is no evidence that this method can shorten the gap between the United States and ECMWF.
If we want to develop the best numerical forecast model, managers must have the vision and ability to comprehensively deal with all components of the weather forecast system, and pay attention to specific details, so that all components can be exquisitely combined into a complete forecast system. This is a hard job, but as Rudd has heard many times in ECMWF, there is no shortcut.
As an American scholar, Mr. Rude analyzed the development of American numerical forecasting model, which is a kind of reflection and criticism. Maybe it's not comprehensive or completely accurate. However, by comparing the different practices in the field of numerical weather forecasting in Europe and America, it should give some enlightenment to the scientific and technical personnel and managers in related fields in China. Although the United States is not as good as the European Center in the level of numerical forecasting model, it has a deeper foundation in basic scientific research and supports its business ability to reach a higher level. If the development mode is well adjusted, catching up is powerful. However, there is still a gap in these two aspects in China, with insufficient basic research and systematic consideration. The task of shortening the distance from the advanced level is quite arduous, and there is still a long way to go. However, it is very necessary and beneficial to strengthen the observation and analysis of the outside world, pay attention to summing up and learning good practices and ideas, face up to the shortcomings in development and learn from experience.
There are many factors contributing to the success of the European Numerical Prediction Center. Rudy's view deserves special attention, that is, how to establish a scientific organization system, not just the organization of scientists. There are not enough qualified scientists in China, but the benefits of this scarce resource are not satisfactory. One of the reasons may be related to the lack of scientific organization system. In particular, applied scientific research, only guided by projects, papers, awards and professional titles, is not enough to motivate scientists to solve practical application problems. We should grasp it from the aspects of goal orientation, problem orientation, talent structure, open writing, system design, experimental platform, inspection and evaluation, gradual improvement and effective management. And give the final evaluation from the overall effect of scientific research and application, rather than some contributions of a scientist.

The United States has almost all the climate types in the world. In major agricultural areas, severe droughts and floods rarely occur, and the temperature is mild, so sufficient rainfall can be obtained.
The climate of the United States is mainly influenced by the Arctic air flow, which brings a wide range of low pressure from the Pacific Ocean every year. These depressions carry a lot of water when they pass through the Sierra Nevada, Rocky Mountains and Cascade Mountains. When these pressures reach the central plain, they can recombine, leading to the encounter between the main air mass and severe thunderstorms, especially in spring and summer. Sometimes, these rainstorms may merge with other depressions, continue to spread to the east coast and the Atlantic Ocean, and turn into stronger northeast storms, resulting in large-scale heavy snowfall in the middle of the Atlantic Ocean. Easter America and New England. The vast grasslands of the Great Plains have also formed many of the most extreme climate changes in the world.
The height principle of great basin area and Columbia River is arid area, with little rainfall, and the average rainfall is less than 15 inch (38 cm) in the driest time. The southwestern United States is an arid desert. In the hottest weeks of summer, the temperature exceeds 100 degrees Fahrenheit (38 degrees Celsius). The southwest and washbasin areas will also be affected by the monsoon from the Gulf of California, occasionally bringing rare heavy rains. Most parts of California belong to the Mediterranean climate, which sometimes leads to heavy rain from June 5438+00 to April the following year, while it hardly rains in other months. The northwest region near the Pacific Ocean is rainy all the year round, but the rainfall is the largest in winter and spring. The western mountainous area absorbs enough water, and the rainfall and snowfall are quite heavy. Cascade Mountain is one of the places with the largest snowfall in the world, but there is not much snowfall in the coastal areas with low altitude.
9. The weather in new york.
The temperature in new york is equivalent to that in Qingdao!
At the same latitude, China is colder than the United States when it is cold and hotter than the United States when it is hot.
Online weather data in the United States: the annual average low temperature is 6 to17; 1 month average temperature-3/4; The average temperature in July is 18/29.
Affected by the cold current from the Arctic Ocean in northern new york, the temperature in the United States may be close to-10 degrees, and 1888 has set a record of-17 degrees. But the average temperature in winter is only a little lower than that in Shanghai and a little higher than that in Beijing and Tianjin. Generally speaking, the weather in new york is similar to that in Qingdao and Weihai in China. The climate in Jiaodong Peninsula is mainly continental, but it is regulated by the ocean because it is close to the sea.
