The expert of China Meteorological Administration analyzes the meteorological condition and non-proliferation issue of the nuclear pollution
At present, the nuclear accident of Fukushima of Japan becomes the focus that the whole world pays close attention to. Question of function,etc. that on the issue that meteorological condition and nuclear radiation pollute and spread, the meteorological phenomena service produces in nuclear accident and environment meet an urgent need and respond to, www.xinhuanet.com and China Meteorological Administration website has specially interviewed the expert of China Meteorological Administration, they are that chief predictor, country of Central Meteorological Observatory are nuclear to meet an urgent need to coordinate the committee expert to consult Sun Jun, expert of group, basic system committee nuclear emergency operation expert panel member, national meteorological Song ZhenXin, senior engineer of centre of World Meteological Organization. Reporter: After the nuclear accident accident of Fukushima of Japan happens, set up and respond to the centre to take action in World Meteological Organization and regional environment of Beijing of International Atomic Energy Agency of the national meteorological centre of China Meteorological Administration immediately promptly, in will it be about 10 o'clock March 12, related departments of running etc. send out " influence to our country in the three day such as nuclear leakage such as nuclear power station such as Japanese " to meet an urgent need by the State Council as soon as possible Project service material,last moods panic that is public. Now we want to know to the expert, have something to do with the nuclear pollution and meet an urgent need and predict that serves, what kind of function does China Meteorological Administration produce? What kind of duty is born? What concrete measure has China Meteorological Administration taken after Japan's earthquake? World Meteological Organization basic the intersection of system and the intersection of committee and nuclear the intersection of emergency operation and the intersection of expert panel and member, national meteorological Song, senior engineer of centre, shake prosperous Song to shake prosperously: After Ukraine cut Noli's nuclear accident and happened in 1986, caused very great influence on the lives and properties of atmospheric environment and people. In this case World Meteological Organization and International Atomic Energy Agency want to know how the coverage that nuclear pollutant spreads at a long distance, spread route are. Because of this consideration, World Meteological Organization and International Atomic Energy Agency successively asserted 8 professional meteorological centres in the whole world, there are 3 in Asia these 8 are professional in meteorological centres, including cloth Nice gram of Beijing, Tokyo, Japan, Russia, three centre these responsible for the intersection of Asia and the intersection of core and radioactive emergency of material of area respond to and work mainly, other having U.S.A., Canada, Britain, France,etc.. The national meteorological centre of China Meteorological Administration is at the 11th meeting of World Meteological Organization of 1996, confirmed as one of the three centres of Asia, begin to fulfil the duty on July 1, 1997. Do we bear any duty concrete? There are the duties of three respects. First, to World Meteological Organization and International Atomic Energy Agency, after the nuclear accident happens, we should provide the products stipulated for it, include the pollutant spread and spread the orbit at different height in 72 hours, and separate the distribution of the radioactive material density of the core in the 24-hour atmosphere, and the distribution to the surface subsidence each time. Second, to completely forbidding the convention CTBTO of the nuclear test, they have mainly wanted recently to know where cores are exploded and happened during these years, global observation station of it, data these pass we to in real time, we regard as core explode where does it take place really through data these, and then to regard as original position, the the intersection of job and in the world 8 centre participate in, it gathers to be here 8 products of centre, we form a comprehensive thing, are done this thing by CTBTO. In addition, domestic core meet an urgent need it is core of country that meet an urgent need, run, take place leakage or meet an urgent need service that respond to to domestic nuclear power plant mainly, we turn towards the material the Central Party Committee, meet an urgent need, run relevant ministries and commissions in country, provide service material to national core. It is the centre that World Meteological Organization and International Atomic Energy Agency assert that regional environment of Beijing set up in the national meteorological centre of China Meteorological Administration responds to the centre promptly, the response is very fast after this Japanese nuclear incident of leakage happen in centre of ours, we receive International Atomic Energy Agency give whom we send about nuclear position of power plant and after the basic parameter after the March 11, having started our emergent rough estimate mode rapidly, coverage, orbit that the pollutant may spread have been predicted to 72 hours of the following 3 days. And we and Japan, Russia have communicated. Because just China is the country that takes the main responsibility in three regional centres of Asia in 2011 years, we have communicated with our predictor too after predicting the data are sent, have communicated to the weather situation, wind direction of the high altitude low latitude, wind speed in the following several days around the nuclear power plant of Japan, and the Japanese meteorological agency is that a emergency responds to the centre, discusses with our forecast result with their meteorological expert on the weather situation, we jointly formed the joint announcements of one and three three centres of Asia approved finally, spread to International Atomic Energy Agency and World Meteological Organization. And form a decision material, meet an urgent need and run sending out to the State Council as soon as possible. It is on duty in a whole day of 24 hours that the regional environment of Beijing responds to the personnel of the centre promptly now, the operational mode, do the rolling forecast in the following several days in real time two times a day. Make one assessment of atmosphere to the intersection of future and area, range that nuclear leakage might influence. Reporter: What way does nuclear radiation pollute relying on mainly to spread and spread? What kind of influence does meteorological factor or weather condition have on that pollutant is spread? The chief predictor of Central Meteorological Observatory, country are nuclear to meet an urgent need to coordinate the committee expert to consult Jun Sun Jun Sun, expert of group: Because mainly been at present the leakage of some nuclear pollutant has happened in this regional nuclear power station of Fukushima of Japan, the nuclear pollutant mainly has two conditions to spread, one is air, the nuclear pollutant is entered in air, as the flow of the air is spread. Another condition, because Fukushima of Japan is in the seashore, perhaps some pollutant will enter the sea, as ocean current and wave are spread outwards. But spread through the flow of the air mainly. The impact on diffusion of the pollutant of the meteorological condition is mainly two o'clock, one is wind, the impact on its diffusion of the wind speed is a very important condition. If the nuclear radiation pollutant leaks to the air, the wind in this place is weaker, the atmosphere is more stable, in this way its pollutant is not basically easy to spread, apt to gather here, its diffusion ability is a little worse. But if the wind speed is larger, the flow of the wind speed is quicker, in this way the pollutant will be spread with the low reaches of wind direction after ranking out. And the speed spread is directly proportional to with the wind speed directly, the larger the wind speed is, the farther the distance transported outwards is. Mentioned just now it was a horizontal direction that spread with the wind speed. The air is three-dimensional, not totally going according to the horizontal direction, some turbulance moves in the atmosphere, there is flow of upper and lower air, in this way the air is when spreading outwards, perhaps also some rise or drop, that is to say to have some happens to subside in particles of some pollutant, land to the ground. There is corrupt some It will be with the ascending sports of the air to dye things, since where it is is discharged out, is it compared that basically overhead? �� widow Pan �� Nao Yu Wood oh Qu last zinc support Qi getting more detailed to knock mother favore with decayed tooth have getting more detailed to knock mother favore with people widow Nao Dun ��, Man of Europe pace up and down to lower peaceful slowly in Yi �� slowly in award in the � s celestials in the Rongs U The strong palm �� Ju �� of nice food is peaceful ? Another condition with more important influence is the precipitation. After raining, pollutant will be mixed with rainwater together, and land with the rainwater to the ground, also unfavorable to the pollutant to further spread outwards. If basically present the rainfall, pollute the area that arrives and lands. If rain and wind combine together, when the cloud department of the rainfall or cloud group of the rainfall travels with low reaches of wind direction, also may take pollutant to some places in the low reaches. One is wind, one is rain, there is heavier influence in the diffusion of the pollutant. Set up national meteorological World Meteological Organization with the intersection of International Atomic Energy Agency and the intersection of Beijing and regional environment of centre respond to the intersection of centre and the intersection of village and white feather it takes a photograph of meteorological experts to be urgent promptly in China Meteorological Administration Piece analyze pollutant, nuclear radiation of Japan, spread the intersection of situation and the intersection of village and pale feather, take a photograph of a reporter: China Meteorological Administration have one nuclear to meet an urgent need, respond to the prediction scheme a intact one? Were we engaged in some such emergency and services in the past? What kind of experiences are there? Song ZhenXin: Beijing regional environment respond to centre promptly, meteorological centre already time for one year to this year since fulfilled in July of 1997 in our country. We participate in international domestic to work about nuclear response that meet an urgent need 14 year. We have made a very intact one nuclearly and met an urgent need to respond to the prediction scheme. Tell the emergency preplan of world at first, the emergency preplan of world is mainly for International Atomic Energy Agency for each month, each quarter, held the nuclear emergency drill of some different scale every four years. It can give us take place some order while being fixed each month, for example, how many nuclear power plants want nuclear the intersection of accident and leakage to happen while being false the whole world, let us make the products to spread out, there are some manoeuvres each quarter and and have some global very large-scale manoeuvres every four years, also mainly for the nuclear power plant, the whole world selects different nuclear power plants to do the manoeuvre. After we receive International Atomic Energy Agency and send out the fax or mail that the core had meets an urgent need and responds to to us, we will start our mode, products according to some parameters that it offers soon, calculate orbit, density for 72 hour and subside, product these according to the requirement which it appoints we, send the webpage to a special union centre of meteorological organization, upload these products on the webpage. And we want the size of the scale according to it, should write the joint statement, we discuss with Japan, Russia that write this report in Asia. International Atomic Energy Agency and World Meteological Organization should open experts once to know every two years, through this series of manoeuvres, quote some questions, we should discuss the standard, form, transmission way, website of products of these rule, products, there are a series of regulations. So, we are in constant completion. Another one, the nuclear emergency maneuvre of our country, the meteorological centre of our country has specially made the prediction scheme that a core meets an urgent need and responds to, we have an intact procedure, after we receive the national core and meet an urgent need in running, International Atomic Energy Agency and national relevant ministries and commissions for the signal or notice which we send out and ask to meet an urgent need and respond to, the office notice of meeting an urgent need through China Meteorological Administration at first, our attenbant will start this data to predict the mode very in time, after producing our products, want the change of the weather situation by the discussion of weatherman of Central Meteorological Observatory, combine together to the forecast result of weather situation and us, we should write the service material of a decision. After this material takes shape, the issuing of related departments of China Meteorological Administration, report these places of to the relevant ministries and commissions of the State Council, national core to meet an urgent need and doing etc.. The third respect, completely forbid the convention of the nuclear test, according to the reverse source of observation station, we have some procedures too, it has normal products too, the products form which we will stipulate according to CTBTO, upload the products of our each manoeuvre to the websites which it stipulate after producing, it is fixed will give us the information of some feedback. Between these 14 years, we really did many manoeuvre tasks. Certainly the real nuclear leakage is Japan's the nuclear power plant lets out this time in the world, with before great majority drill,like emergency maneuvre which each of us piece make until month, unless it involve Asia, Europe, America, it is global different power plants nuclear,may this month which stations is Asia, the manoeuvre will choose different imaginary nuclear accidents from the global different places from America or Europe next month. In this way we mainly offer some regular service product, there are some analysis reports. Numerous at home, we participated in one 2009 national core will meet an urgent need and do the national emergency maneuvre regarding the nuclear accident has been let out held recently at first, we want its influence, range, route after leakage to happen false to 5 particular nuclear power plants in our country, how personnel dismiss from, we should mark an area, and where is density to spread every other hour, how are the wind directions, have all made the work in this respect. In addition, because to in the world, what we did is that global long distance diffusion is studied, to our country, what we did is mainly meticulous yardstick, the resolution ratio is higher, area that can make it of 15 kilometers predicts. More meticulous system of cooperating some more does some work, like some emergent services which we do, the Guangzhou Asian Games recently, it is not certainly that the core meets an urgent need and responds to, spread for example how chlorine explosion is leaked. Waiting a moment in Beijing Olympic Games, World Expo 2010 Shanghai does some services. Some sudden ones, for example transport the unexpected explosion of car of the dangerous article on the expressway, overturn, articles are let out, cause spreading to the locality, we of very little yardstick do too. In addition, at home, in some provinces, the weather bureau receives the local radioactive material, there are fewer radioactive materials, it is mainly the diffusion that non- nuclear chemistry is poisonous, we do such a service too. Through these services of more than ten years, we accumulate some experiences both at home and abroad, mainly our forecast mode is more and more meticulous, the products predicted relatively accord with the requirements of World Meteological Organization and International Atomic Energy Agency too, and our action is very fast, we can calculate the result after starting the mode in more than ten minutes after receiving the order, can form our decision service product in half an hour. The regional environment of Beijing responds to the centre and passes the construction of several decades promptly, has accumulated more abundant experience too in this respect. Reporter: Another net friend compares the question paid close attention to, the masses of our country worry about pollution of Japan's nuclear radiation, ask experts to discuss the nuclear accident Some future weather conditions of the area, and development moving towards and trend that nuclear radiation pollutes, whether have influenced our country. Sun Jun: Is the public to Japan? The first day of the lunar month �� Lai last Xing of neck of Zhyuan mirror S lead to hack last � V to finish dai, take off Yue oh � leg felt mortar sledge until night such as �� such as leech such as �� such as mould such as badger �� nice food tip high mountains strong? About 000 kilometers. So, the accident happens to present nuclear radiation to let out pollution in its nuclear power station, especially the ordinary people of our country express this respect to care about very much, whether the pollutant can influence our country, can influence oneself. Regional environment respond to centre promptly about Beijing, Song shake so prosperously as to describe too just now. They have just begun to make the nuclear power station and leak the diffusion of radioactive pollutant that may be produced since earthquake, begin to make some analysis and predict the products to this respect, make two issues each day, have pointed out too on the products each time the nuclear pollution of the following three days has no effect on our country. The net friend may have some misunderstandings, we write that the following three days is not influenced, is there influence three days later? Because we to make, predict, predict, must have one period of period, in 3 day this period, the dependability predicted is a little higher, dependability will drop gradually three days later. So, predict in present a short time that provides the forecast of three days. We can roll, upgrade, predict, release products that predict newly constantly gradually every day in the three day. According to present situation, I may prove, the net friend will understand further that know some with these pictures, forecast products why we release every day, say the pollutant has no effect on our country. Because the pollutant is mainly spread as the main fact through the flow of the air. Have a look at Japan to the situation of atmospheric circulation over our country at first, this is description of the general newest live situation of this morning. This is the island of Japan, Fukushima area somewhere around here, a blue arrowhead has been drawn in the east of the island of Japan, basically express the wind direction this morning in the northerly, the southwest side in Fukushima of Tokyo, this wind direction is basically to blow in this direction in Tokyo, there was some information too on the net yesterday, say Tokyo has seen some nuclear pollution too, this may have some relations with wind direction. Watch the wind directions of this area of our country and the sea of Japan again, blue arrowhead expresses wind directions of the ground, this whole generation of area is northwester or the west, this nears the stratum, probably under 100 meters are this wind direction. High to see some, getting red two-way arrowhead say one layer high, 100- 1500 general trend of wind direction, whole this is basically air current to the west. So even if this piece have some diffusion of pollutant, from lower to lean towards the south, spread it, if the pollutant has reached higher level, basically spread to the north Pacific Ocean area of the east of Japan, would not spread to the area of this area of our country at all, this is today. We saw the general situation of tomorrow again, mentioned just now there is some northerly in this area, the area of this area will begin to influence the area of this area of Japan with the cold air by tomorrow, this area is transferred to northwest air current from area to high altitude, unfavorable to the pollutant to spread in the direction to the west like this, and from low to high, the wind directions are still more unanimous, all spread to the area of this area of the Pacific Ocean. This is tomorrow's situation. See situation for 18 day again, change somewhat two day closer, to party this to spread basically in a few days ago, this regional wind direction will be changed to some extent by tomorrow, will transfer from northwest west to northwester, in this way the diffusion direction of the pollutant is spread to the area of this area of southeast Pacific Ocean, will not influence the coastal area of our country either. So according to demonstration situation of this picture, area this wind of area to of our country side to blow, so everybody needn't afraid the pollutant will influence our country with the wind direction.
