Zhu Kezhen: "Now we realize that the Gaoyou Lake air mass on March 3 is a very evil phenomenon, which is almost decisive for the weather in the next 3 days. However, the weather data of Gaoyou Lake is not detailed enough. The main reason is that there is no meteorological system in the center of the lake. Observing the buoys. But based on the data of the two weather stations by the lake, the results are very uncertain."
Tu Changwang: "I have ordered the engineering team of the Meteorological Bureau to add an automatic weather buoy in Gaoyou Lake. It seems that in the future, such large-scale lakes will have buoys in the waters of the lake."

天河一号每次运算需要全功率开机21小时左右，运算结果从1天后到第15天。2月27日起，国家气象局就每天都查验各地天气是否和天河一号的运算结果相符。
The results on the 27th and 28th were very exciting, more accurate than the previous hand calculation + limited computer assistance, but this was expected. How much the accuracy rate will drop after 10 days is the key assessment point.
3月3日下午，气象观测数据把之前很不乐观的形势一下子逆转了，竺可桢当即就推断，2月26日运算出的26日~3月13日中长期预报有可能是对的。
3月4日，根据3月3日的气象观测数据做的第四次运算结果出来，这回淮河两岸及淮南地区3月10日的天气预报又回到了2月26日预报时的状态。当然，此时已经不是10~15天的中长期天气预报了，3月4日的结果一直推算到了3月19日，3月10日只是整个时间段的中间点。
——However, the 7-day medium-term weather forecast is almost blank now.
"Director Tu, all of you from the Meteorological Bureau plan to wait until March 3 for all the results of the first medium- and long-term weather forecast to be confirmed or falsified?" Tang Hua asked.
Tu Changwang: "Yes."

Shanghai Minhang Heavy Machinery Factory.
"Now, we can be said to have become the sixth country that can manufacture [-]-ton hydraulic presses by itself."
Shen Hong and comrades from the Heavy Machinery Bureau held an on-site meeting with Tang Hua at the Minhang Heavy Machinery Factory.
The 1950-ton hydraulic press, even in Western industrialized countries, is a super-large industrial equipment that only a few countries can produce. In 1951, there were only four countries that could manufacture [-]-ton hydraulic presses: the United Kingdom, the United States, West Germany, and Czechoslovakia. In [-], the Soviet Union entered the ranks of self-made [-]-ton hydraulic presses.
——Yes, the Soviet Union upgraded its self-made hydraulic press from 8000 tons to 12000 tons with the help of the Czech Republic after the war.
Before making its own 2-ton hydraulic press, China had purchased two Czech 12000-ton hydraulic presses, one in Shanghai and one in Fularki.But this thing is expensive and not easy to transport. In the future, there will be a great demand for machining in China. It is roughly estimated that by the end of the Second Five-Year Plan, the country may need a total of 4-5 12000-ton hydraulic presses and at least 5 6000-8000-ton hydraulic presses. .
In 1956, Shen Hong made a report and proposed to develop China's own hydraulic press, which soon entered the development process as a key project of the Heavy Machinery Bureau of the Ministry of Heavy Industry.
……
The hydraulic press in front of everyone is not the domestic product, but the one imported from the Czech Republic.The hydraulic press with a height of more than ten meters is like a big iron man in the special tall factory building. The hot steel ingots are fed in. Under the huge pressure, the high-strength alloy steel ingots are crushed like plasticine, creaking and crumbling.
Then the steel ingot changed its direction, turned over and over again, and successfully completed the operations such as elongation, upsetting, and cutting, and a long steam turbine main shaft was born in this way.
Tang Hua: "In Dalian, I hope that some remaining design defects can be resolved as soon as possible. After the adjustments are completed, the Dalian machine will officially pass the national acceptance."
Shen Hong: "I have a preliminary solution to the problem of excessive deformation in the D area. Taking advantage of this opportunity to have a meeting and exchange in Shanghai, I would like to take another look at the [-]-ton hydraulic press in the Czech Republic to see if I can find inspiration from it. .”
Tang Hua: "The hydraulic passage structure of your hydraulic press is different from that of the Czech one."
"So it is to find inspiration. Or, to verify that the solution I proposed is correct."
Tang Hua: "In order to do a good job in the heavy industry mother machine, as well as the whole heavy industry, you have to let go of the knot in your heart. There are still some comrades who are frightened when they mention the three terms large, precise, and complex, and don't think about it. People didn’t have anything 100 years ago, why did they develop to this point, we can’t.”
"Let me give another example. The first 1950-ton ship designed by Shanghai Ship Design Institute and built by Jiangnan Shipyard was completed. The maiden voyage was very smooth. We have never built a 1952-ton ship. The ship design institute was built in [-]. It was only established in [-], and it was only in [-] that it started to do design work. When many comrades heard that they wanted to design the [-]-ton wheel, their scalps became numb.”
"At this time, Shigeru Makino from the Ship Design Institute came out to calm everyone's emotions. He first asked the designers to eliminate their fear of independent design. Shigeru Makino said that we did not get a complete set of drawings of any foreign [-]-ton ship , This is true, but it is not a particularly big difficulty. Isn’t the [-]-ton round a big ship? What is your job, is to design ships.”
Shen Hong and the comrades from the Heavy Machinery Bureau had just designed a [-]-ton hydraulic press by themselves, and heard that the Ship Design Institute had also done a similar feat, and they immediately resonated in their hearts.
"This Comrade Mu seems to be as powerful as us."
Well, this comrade thought that Shigeru Makino was a Chinese with a surname of Mu.In China, there are not only people with the surname Mu, but also people with the surname Mu.It seems that Mr. Shigeru Makino is not difficult at all to get through the crowd of Chinese people.
Tang Hua: "Old Shen, the adjustment and repair of hydraulic presses in Dalian must be done. However, from now on, the main manager of your team should be preparing to move to Shanghai to manufacture the second domestically produced 12000-ton hydraulic press. The speed of industrial development in Shanghai has exceeded expectations, and although a [-]-ton hydraulic press was directly imported from the Czech Republic, it seems to be insufficient.”
Shen Hong: "Understood. Minister Tang, I think that the [-]-ton machine ordered by Shanghai will be based on the Dalian machine, and then make some improvements to increase the lifespan and improve the operating efficiency."
Tang Hua: "I fully support this point."

Yancheng.
There was a sleet at the beginning of January, and then until the first month, it was dry and cold continuously, and the northerly wind was sometimes strong and sometimes weak. On March 1, the northerly wind that was still at level 3 or 9 stopped.Then, some old men and women in the villages and towns felt their rheumatic old cold legs began to ache.
"It's a southerly wind, and the tide is back. My old leg is also hurting. Could it be raining?"
"It's really possible."
On the morning of March 3, Qinnan Township in the southwest of Yancheng began to rain spasmodically on an increasingly gloomy day.The raindrops were very small and finely divided, and they were not dense at first.About half an hour later, the rain was finally so heavy that the sound of splashing rain could be heard in the house.
At noon on the 10th, it began to rain in Yancheng in the haze.
The not-so-large precipitation line pushes from Yancheng to the northwest. Yancheng, Jianhu, Yilin, and then the Huaihe River under construction enters the sea. It has been blackened.
"Qinnan Meteorological Observatory, according to the statistics of rainfall in 2 hours and 20 minutes, the rainfall is 20 millimeters."
“盐城一站降雨2小时10分钟，降雨量25毫米，盐城二站2小时20分钟，降雨量25毫米。”
降5毫米的雨，可使旱地浸透3厘米~6厘米。20~25毫米的降雨是刚好可以浸润旱地的程度。从每小时降雨量来算，这是一场小到中雨。
……
Comrades from Shanghai Institute of Computer Science, Tu Changwang and Meteorological Bureau have started the celebration.
"Thank you, thank you comrades at the Institute of Computer Science." Ye Duzheng shook hands with Lebedev and Wang Shoujue.
Zhu Kezhen walked between the four Tianhe-[-] cabinets standing in the supercomputing hall, looking at this era-changing artifact.
"It will not only completely change weather forecasting, but also revolutionize meteorological science," Zhu Kezhen said. "Everything is different from before."
"The first medium- and long-term weather forecast calculation, until the 12th day, the accuracy rate of the weather forecast in the Huanghuai area reached 73%, and the first spring rain in the Huainan area was accurately predicted, and the accuracy of the rainfall area prediction was 80%. The Lianshui calculation is correct except that the rainfall does not actually fall; the accuracy of rainfall prediction is 66%.”
"For the weather forecast on the 12th day, the accuracy rate is generally not bad." Tu Changwang said, "There are still the last three days, and we insist on reading all the results."

Copenhagen.
The third summit of the International Geophysical Year for Atmospheric Sciences was held on March 3.
One and a half months ago, at the second academic summit of IGY, Wu Youxun read the paper jointly written by Ye Duzheng and Zhu Kezhen on behalf of Ye Duzheng and Zhu Kezhen, and announced that Chinese meteorological researchers and the China National Meteorological Administration are conducting an important research on geophysics and meteorology. A major breakthrough is about to be accomplished.
Then, European meteorologists waited for Ye Duzheng or Zhu Kezhen to attend the third summit.
On March 3, the third summit entered the schedule of the Atmospheric Physics Symposium. A Chinese person appeared at the venue. He was neither Zhu Kezhen, Ye Duzheng, nor Wu Youxun, but Wu Qiyue, the counselor of the Chinese Embassy in Switzerland.
He was sent here because Wu Qiyue graduated from the Southwest Associated University and studied for a master’s degree in Paris among the staff of our embassy and consulates in Europe. read out.
This is too unkind, let us release our pigeons for the second time.
