That a tornado and hail disasters killed 13 people, 825 people were injured, about 1.42 billion yuan of direct economic loss.
Yancheng why tornadoes are a common occurrence?
Jiangsu provincial Observatory chief forecaster surging Han Guirong told journalists, is located in the North Jiangsu plain in Yancheng, East of the Yellow River, flat terrain, rivers and lakes are intertwined, in subtropical and warm temperate climate transition zone of instability likely to build up, forming a tornado.
Han Guirong said, not only in Jiangsu Yancheng are prone to tornadoes, gaoyou, Yangzhou, Taizhou and other places are also prone to tornado disaster.
As for why such a violent tornado in Yancheng, said Han Guirong said there is not good. Homeland officials in Chengdu became political
Is strong tornadoes occur most frequently in Jiangsu Province
Public information, according to Fujita series (Fujita Scale) tornado EF0~EF5 six levels which can be from weak to strong, EF0 wind speed 100~140 km/h, EF5 wind speed 331~390 kilometers per hour.
At the national level, is strong tornadoes occur most frequently in Jiangsu Province.
According to the weather network, 1961-2010, these 40 years, occurred in Jiangsu EF3 tornado 9 and above, EF2 tornado 27 times, most are national.
Pan Wenzhuo now served in the Hangzhou Meteorological Bureau in Jiangsu Province, a tornado distribution characteristic and its disaster assessment in the article, 50 years, Jiangsu Province disaster tornado statistics and information, conducted a study on distribution characteristics of tornado in Jiangsu Province.
Rescue work in order, all work together to repair.
Research, spatial distribution of tornadoes in Jiangsu province to coastal and inland little coastal distribution for the South North little. Seen from the time, Jiangsu Province, mainly occur in the summer of the year; in a day, mainly in the afternoon.
According to Fujita series classification, the article on tornado frequency distributions was analyzed at various levels. Results showed that EF0 in Jiangsu Province, which is the lowest level has the most tornadoes, 70 per cent of the total number of times. 3% for EF0~EF3 tornado frequency distribution at all levels, always high value areas in Southeast Jiangsu and decreasing frequencies from the Yangtze estuary to inland; corresponding to Nanjing, Suqian and tornado in a low incidence area at all levels.
Through a strong Tornado and strong tornado frequency distribution analysis, the article concluded that high incidence of strong tornadoes in Nantong, Jiangsu Province and its nearby Yancheng, Taizhou, Xuzhou is also a higher incidence of area.
Accurate early warning tornado is the world's toughest problems
At present, accurate early warning of tornadoes was a world-class problem.
Relief workers on down the road.
Surging journalists noted that Jiangsu provincial Observatory official micro-blog on 23rd 2:29 Tweet says, "the Yancheng's friends note that increased echo in Funing, now 65dbz, need to guard against short-time strong precipitation thunderstorm convective weather, try not to go out."
However, little issued on Twitter at the same time, disasters have occurred.
CMA official micro-blog posting said tornadoes occur in short time, influence, instrument monitoring and forecasting difficult. Currently needs further monitoring, early warning of severe weather and small scale systems, improved Doppler radar monitoring and inversion of the capability of the tornado.
United States renowned weather expert mate·dannier 2015 once published an article saying, accurate forecasting of tornadoes are possible in the future, but at least people now haven't mastered skills, because there are too many variables to add tornado prediction algorithms. Mate·dannier said the best prospects for inclement weather, is to fully understand the climate, the local climate was scientifically studied.
