Original title: Jiangsu tornado-prone areas, China is forecast to be the world's toughest problems

For around 22 o'clock, Beijing, reporters rushed to the scene, Yancheng solar – GCL sunshine electric power technology co., Ltd. Is still with light rain, a large number of fire and police in the rescue, pulling at the door line. Tents were put up at the entrance of the company, for use by the rescue workers, firefighters and ambulances keep. Beijing, Xinhua Gu Hua photography

CNS, Nanjing, June 24 (reporter Cui Jiaming)-Jiangsu China tornado-prone area. Why do tornadoes annually ravaged Jiangsu? The night of 23rd, Jiangsu provincial Observatory, experts say this is due to the low-lying flat, interwoven network of rivers and lakes in northern Jiangsu Province, in subtropical and warm temperate climate transition zone, easy accumulation of unstable energy, help to tornado formation.

"Tornadoes are funnel-shaped clouds of a thunderstorm cloud base extended to the ground, resulting in intense cyclones. Wind of 12 or more, the maximum can be up to 100 m/s or more, generally accompanied by thunderstorms, sometimes accompanied by hail. It is the strongest Vortex phenomena in the atmosphere, sphere of influence may be small, but devastating. "Experts say strong tornado occurred mainly in spring, summer and early fall, with July up, followed by April. "China has the seasonal characteristic of the strong tornado. ”

The afternoon of June 23, Ning suffered strong convective weather in Yancheng, Jiangsu Province, heavy rain, hail, and tornadoes combined attacks, casualties is huge, heavy losses. That night (23rd) at 22 o'clock, the Ministry of Civil Affairs announced, according to preliminary statistics, deaths due to disasters caused by strong convective weather 78 people, injured nearly 500 people for disaster, which injured nearly 200 people and larger number of houses damaged in the affected areas, electric power communication facilities were destroyed, power outages in some areas, communication base station signal. Specific loss is further verification.

For the cause of the tornado disaster. According to meteorological experts, Jiangsu Province: 23rd in huanghuai area in northwest of subtropical high margin, high temperature, high humidity, convection potential well. The same day, cold Vortex Yancheng high altitude to cope with trough moving East South East to move lower in low shear, cyclones, cold air at the back. Lower Southwest jets, middle and upper Northwest jet stream, the strong wind shear, has strong wind direction and wind speed on the ground under a convergence trigger, producing tornadoes.

The hail, tornadoes, hazardous extreme weather occurred in Jiangsu, experts said, as it happens, this is not happened in the past.

Footprints left by Combs for more than 10 years tornadoes in Jiangsu, reporters found that tornadoes also have their own unique preferences: "sticky" in gaoyou, "bias", and yizheng baoying, jiangdu. In this regard, the meteorological expert analysis of Yangzhou, tornadoes can easily form in gaoyou's reason was simple, gaoyou is located in the most low-lying plains, because, like a big pot, surrounded by ditches and lakes, easy to create the conditions for the formation of a tornado. Due to special geographic environment and not only tornadoes and other extreme weather like "harassment" in gaoyou, baoying, Yangzhou, jiangdu etc, lightning like run these places.

Meanwhile, experts say, from a macro point of view, increase in severe convective weather, became the breeding ground for tornadoes and strong convective weather increased the culprit, is global warming.

Meanwhile, experts say, wind speed determination is the world's toughest problems, tornadoes, hail, thunderstorms are the product of weather, is very similar to their precursor, when one can have these kinds of weather phenomena for the convective rain clouds come, it's hard to tell what the cloud brings hail or tornadoes. "Even if instrument waiting for the scene, are often destroyed by the tornado. "(End)

江苏苏北是龙卷风多发地区 预报是世界级难题|龙卷风|江苏苏北_新闻资讯

　　原标题：江苏苏北地区是中国龙卷风多发地区 预报是世界级难题

　　中新网南京6月24日电 （记者 崔佳明）江苏苏北地区是中国龙卷风多发地区。龙卷风为何年年肆虐江苏？23日夜，江苏省气象台专家说，这是由于苏北地区地势低洼平坦、江河湖泊水网交织，处于亚热带和暖温带的气候过渡地带，易积聚不稳定能量，有助于龙卷生成。

　　“龙卷风是由雷暴云底伸展至地面的漏斗状云，产生的强烈的旋风。其风力可达12级以上，最大可达100米/秒以上，一般伴有雷雨，有时也伴有冰雹。它是大气中最强烈的涡旋现象，影响范围虽小，但破坏力极大。”专家称，强龙卷主要集中在春夏两季和早秋发生，其中7月最多，4月次之。“可见中国强龙卷的发生有明显的季节性特征。”

　　6月23日下午，江苏苏北地区盐城阜宁遭遇强对流天气，暴雨、冰雹和龙卷风联合袭击，伤亡巨大，损失惨重。当晚（23日）22时，国家民政部发布消息，据初步统计，强对流天气造成因灾死亡78人，因灾受伤近500人，其中重伤近200人，受灾地区房屋倒损数量较多，电力通信设施被破坏，部分地区电力中断，通信基站无信号。具体损失正在进一步核实当中。

　　对于本次龙卷风灾害的成因。据江苏省气象台专家分析：23日，黄淮地区处于副高西北边缘，温度高，湿度大，对流潜势好。当天，盐城地区高空有冷涡配合低槽东移南下，中低层有低涡切变东移，地面有气旋，后部有冷空气。低层西南急流，中高层西北急流，存在强的风切变，在地面有强的风向风速辐合触发下，产生了龙卷风。

　　这次冰雹、龙卷风灾害性极端天气同时发生在江苏，专家表示，非常巧合，这是以往没有发生过的。

　　梳理10多年龙卷风在江苏留下的足迹，记者发现，龙卷风也有自己的独特喜好：“最黏”高邮，“偏爱”仪征、宝应、江都。对此，扬州气象台专家分析，龙卷风极易在高邮形成的理由很简单，因为高邮地处平原最低洼处，像个大锅底，四周沟渠湖泊密布，容易为龙卷风的形成创造条件。由于地理环境特殊，不仅龙卷风等极端天气喜欢“骚扰”高邮、宝应、仪征、江都等地，雷电天气也喜欢往这些地方跑。

　　同时，专家认为，从更宏观的角度来看，强对流天气增多，成为了龙卷风的温床；而强对流天气增多的罪魁祸首，是全球气候变暖。

　　同时，专家直言，风速测定是世界级难题，龙卷风、冰雹、雷暴都是阵性天气的产物，它们的前兆十分相似，当一片可能产生这几种天气现象的强对流积雨云袭来时，很难判断到底这片云会带来冰雹还是龙卷风。“即使仪器守候现场，往往也会被龙卷风摧毁。”（完）
