It has caused 5 deaths and 7 missing in Shandong, 39 deaths and 9 missing in Zhejiang, and 73 rivers have exceeded the police … … The super typhoon "Lichima" has caused great losses to many coastal provinces and cities. What is the origin of "Lichima"? Have local emergency plans played their due role? What other aspects should we pay attention to in the next step to deal with the "Lichima" invasion? Xinhua News Agency reporters visited the front line of fighting against typhoons and launched an investigation.
"Lichima", "Naughty Sea" and "Soft Meng" fruits are named super typhoon.
According to the reporter’s understanding, "Lichima" is a tropical fruit with a "soft and cute" image and a close taste. I don’t want to become the name of the third strong typhoon that landed in East China in 70 years. According to experts, "Lichima" has become the fiercest typhoon this year because of its violent storms.
— — Gale. The previous typhoons "Muen" and "Weipa" were tropical storms when they landed, and the winds were 8 and 9 respectively, which was far lower than the maximum wind intensity of 16 when "Lichima" landed. On the morning of the 11th, there were 8-10 gusts in northeastern Jiangsu, northeastern Anhui, northern Shandong and southern Bohai, and the local gusts in Qingdao and Tai ‘an in Shandong could still reach 12.
— — Rainstorm. The huge rainfall brought by "Lichima" also threatens the safety of relevant places. As of the 10th, the rainfall in Taizhou, Zhejiang, northern Wenzhou, southern Ningbo and southwestern Huzhou reached 350-580mm, 829mm in Kuocangshan, Taizhou and 706mm in Sanmen. At the same time, heavy rain or heavy rain occurred in Shanghai, Jiangsu, central and eastern Shandong, eastern Anhui and other places, and heavy rain occurred in Weifang and Linyi, Shandong, with rainfall of 250 to 407 mm. As of the 11th, 73 rivers in Zhejiang, Jiangsu, Shanghai, Anhui, Shandong and other places have experienced over-alert floods since August 9th.
Why did "Lichima" bring such huge rainfall? "A typhoon is like a huge ‘ Water vapor absorber ’ Absorb water vapor from the ocean and bring heavy precipitation to the land. " Senior engineer of Typhoon and Marine Meteorological Forecast Center of China Meteorological Bureau explained to Chun Yi that the monsoon input of "Lichima" is very strong, that is to say, there is a cross-equatorial airflow to transport warm and humid air rich in water vapor in the equatorial region into the typhoon, which greatly increases its "water" power.
Since the 8th, "Lichima" has caused many disasters, including landslides, mudslides and urban waterlogging. According to authoritative statistics, as of 7: 00 on the 12th, Typhoon Lichima had affected 6.679 million people, affected 234,000 hectares of crops and damaged 41,000 houses.
Start emergency plans in many places according to law to reduce the degree of disaster.
On the evening of the 8th, Weibo, the official of Qingdao Professional Meteorological Observatory, reported that a report reprinted by Qingdao Municipal People’s Government Press Office issued a typhoon warning in violation of regulations. "Qingdao Meteorology" emphasizes that "if a typhoon warning is issued, the city will start emergency plans, including flood control and resettlement, which is a very serious matter". This little tidbit once again highlights the importance of starting and implementing the "emergency plan" according to law when dealing with serious natural disasters.
According to the reporter’s understanding, the China Meteorological Bureau has launched a Class II emergency response to major meteorological disasters (typhoons), issued a typhoon red warning, and carried out targeted monitoring, forecasting and early warning services;
As the first province to contact typhoon, Zhejiang reserves all kinds of emergency relief materials, and the meteorological department launched the Class I emergency response against typhoon at the first time.
According to the requirements of the emergency plan, Hangzhou has investigated 6,902 farmhouses, evacuated more than 2,000 people and closed 38 A-level scenic spots; According to the movement path, development and influence of the typhoon, Ningbo will continue to do a good job in the transfer and resettlement of people in dangerous areas and the safety management of transferred people and ships in Hong Kong according to the emergency plan.
In Jiangsu and Shuyang County, from 20: 00 on August 11th, the flood control level I emergency response was launched, and 32 towns and villages with 255,000 people’s efforts arrived at the designated position of Xinyi River embankment to patrol the embankment to ensure related safety.
In Shandong, Qingdao fangzhi upgraded the typhoon prevention level II emergency response to level I emergency response at 13: 00 on the 11th. The Water Affairs Bureau keeps a close eye on the largest river course in the city — — Flood control safety of Dagu River. The Culture and Tourism Bureau requires all scenic spots in the city to be closed and stop visiting activities. The Bureau of Commerce requires relevant units to strengthen the organization of the supply of "vegetable basket" commodities such as meat and vegetables to ensure that the market supply is not out of stock and does not stop.
Xie Yuwen, dean of Zhongguancun Zhilian Disaster Perception Science Research Institute, said that timely launching and fully implementing the emergency plan can effectively help all localities control the disaster in the face of major disasters. Shouguang, Shandong Province, was affected by the typhoon, although the rainfall hit a historical record, but the disaster level was significantly lower than last year.
"Wind blowing to the north" plus general disaster risk Northeast China or long-term large-scale precipitation
The reporter learned from the Emergency Management Department of Shandong Province on the 12th that according to preliminary statistics, there were 1,655,300 people affected by the disaster in Shandong Province, 5 people died and 7 people were missing. The affected area of crops is 175,400 hectares, and 609 houses have collapsed. Relevant disaster data are being further counted.
Why "the wind blows north"? Xiang Chunyi told reporters that the subtropical high was relatively strong this year. Under its guidance, "Lichima" did not land in low-latitude Guangdong and other places, but moved to the northwest.
Experts warned that the biggest problem of the current typhoon northward is to directly expose the northern region with less experience in fighting typhoons to the typhoon. Because the northern part of China has a weak ability to withstand heavy rain and generally lacks experience in typhoon prevention, it will greatly increase the risk of disaster, so it must not be taken lightly.
The reporter learned that at present, the expert group of flood control and drought relief technology of Shandong Flood Control and Drought Relief Headquarters is all in place, and professional consultation and judgment have been carried out on the situation of reservoir exceeding flood limit, river flood discharge and mountain torrents prone to occur. Shandong Provincial Defense Index has sent eight working groups to 16 cities in the province to guide the typhoon defense work on the spot, and urged all localities to carry out detailed safety hazard investigation and grasp the key links of defense.
Xiang Chunyi also reminded that the weakening of typhoon landing does not mean that rainfall is reduced. The influence of "Lichima" on the northeast of North China will be long-term and wide-ranging, and the influence of continuous precipitation accumulation will be great.
Experts said that from the afternoon of the 11th to the next 72 hours, there will be large-scale precipitation in the northeast of North China. After 72 hours, there may be some precipitation influence in the east of Northeast China.
