The biggest typhoon in 2007
The gale of magnitude 8 lasted 100 for more than hours.
Heavy rain affects many cities.
Rosa attacked more than 7 million people in Zhejiang.
Remember Chen.
At 0: 00 yesterday, the menacing "Rosa" re-entered Zhejiang from Fuding, and weakened into a tropical storm at 2 am that day. After staying over Wen Tai for 15 hours, it entered the sea from Sanmen Bay at 17:30 last night and gradually moved away.
At 9 o'clock yesterday morning, the leaders of Lv Zushan Province, the deputy secretary of the provincial party committee and the governor rushed to the provincial defense headquarters to inspect and deploy the disaster relief work against Taiwan. Lv Zushan stressed that at present, we should pay close attention to the rain and water conditions, and all localities should pay special attention to preventing secondary disasters caused by heavy rainfall. In the next few days, we should strengthen inspections, monitoring and early warning, and transfer the masses in time once there are dangerous signals. Wenzhou, Taiwan Province and other places have been hit by typhoons continuously. It is necessary to focus on people with difficulties in life, do a good job in resettlement and relief for the affected people, pay close attention to emergency repair of water-damaged projects, prevent post-disaster epidemics, and help the disaster-stricken areas to carry out self-help in production.
Under the unified dispatching command of the provincial defense index, all parts of the province are also actively involved in the work of preventing Taiwan from fighting Taiwan. For example, in Yuhuan, Taizhou, more than 2,000 government officials in the county went deep into the front line of anti-Taiwan, and the emergency rescue team of more than10 3200 people also entered a state of war. Prepare emergency vehicles 170, ships 120, 45,000 emergency sacks, alloy mesh steel pipes, timber and other emergency materials, and put them into emergency rescue at any time.
general situation
A gale of magnitude 8 affected Zhejiang for more than 100 hours.
Rosa's harm is mainly manifested in strong winds and heavy rains.
Let's start with the wind.
"Rosa" has great strength and wide range. Due to the slow moving speed, the impact of strong winds of magnitude 8 or above on Zhejiang has lasted for more than 100 hours. The maximum wind force along the coast of central and southern Zhejiang reaches12-13; The station with the greatest wind power on the coastal sea surface is Dongtou Hutouyu, which is 39.8m/s, and the station with the greatest wind power on land is Cangnan Liao Yu, which is 35.3m/s. ..
Experts from the Provincial Meteorological Observatory said that it is rare for typhoon disasters to last so long in recent years.
Look at the rain.
According to the statistics of the Provincial Hydrological Bureau, under the influence of Rosa, it began to rain in Zhejiang at 8: 00 on October 6th, and at 8: 00 on October 8th, the average rainfall was166.8 mm. ..
The average rainfall in Wenzhou, Taizhou, Ningbo, Huzhou, Zhoushan, Shaoxing and Lishui exceeds 150 mm;
The average rainfall in counties and cities is more than 250 mm in Yueqing, Wenzhou, Yongjia, Ruian, qingtian county, Fenghua, Linhai, Ninghai and Cangnan.
According to preliminary estimates, such heavy rainfall may be second only to the typhoon Haitang in 2005. You know, the rainfall of Haitang has set a record since 1949.

The water level in many places in the province is supercritical.
Heavy rainfall caused many water levels in Zhejiang to exceed critical or warning water levels.
According to the provincial defense office, as of yesterday 17, the water level of Hangchangqiao was 3. 19 meters, and the supercritical water level was 0.03 meters. Xiaomei water level is 2.46m, which exceeds the critical water level by 0. 1 m; The water level of Chen Gong Bridge is 3. 18m, which is 0.02m higher than the critical water level. The upper water level of Linping is 4.34 meters, and the supercritical water level is 0.487 meters. The water level of Chongde Station is 2.35m, and the supercritical water level is 0.19m; Wuzhen Station 2. 1 1 m, with a supercritical water level of 0.25m; Jiaxing water level 1.95m, exceeding the critical water level by 0.09m and Shaoxing by 4.55m, exceeding the critical water level by 0.15m; The water level of Xishan Station is 3.7m, and the supercritical water level is 0.05m.: The water level of Lingxi Station is 5.37m, exceeding the critical water level1.28m..
In addition, the water levels of Meixi, Jiashan and Pingyang stations reached critical water levels; The water levels of Yuhang, Pingyao, Pinghu, Yicheng, Shaoxing and Yueqing stations all exceeded the warning water level.
Traffic on 78 roads was once interrupted.
According to the preliminary statistics of the Provincial Communications Department, due to the influence of Rosa, there are 78 road traffic interruptions in the province, including 2 expressways, national highways 1, provincial highways 12 and 63 county and township highways. Through the efforts of the highway department, at present, except for 7 provincial highways and 48 county and township highways, other highways in the province have been restored to traffic. Traffic signs have been set up at all traffic interruption sections to guide vehicles around.

The slow-moving "Rosa"
Why does it have such a big impact on Zhejiang?
You may have such a question: hasn't Rosa been wandering along the coast of Wenzhou and Taiwan Province? How can it bring storms to Hangjiahu and other places hundreds of kilometers away?
There are two main reasons for this.
First of all, "Rosa" itself is big and strong, and the radius of the 7-level wind circle is basically maintained at 400-500 kilometers; Moreover, after landing at the junction of Zhejiang and Fujian near Xiaguan Town, Cangnan County, "Rosa" likes to stay still and move less, and the moving speed is the slowest, even dropping to 5 km/h.
"The moving path of' Rosa' is slow and complicated due to many factors, such as the complicated terrain of the turning flow and the Taiwan Province Strait." Experts from the Provincial Meteorological Bureau said that the typhoon rotating counterclockwise was like a huge sprinkler. The slower it goes, the longer it stays in the typhoon cloud system, and the more rainfall it naturally has.
Secondly, after "Rosa" landed in Zhejiang, in the northern part of Zhejiang and Hangzhou Bay, its peripheral cloud system just merged with a cold air from the north, causing heavy rain to heavy rain in parts of Hangzhou, Huzhou, southern Shaoxing and Jinhua, and local heavy rain.
Meteorologists concluded that the rainfall characteristics of "Rosa" were somewhat the same as those of Typhoon 19 which landed in Fujian in 2005, both of which were affected by the encounter of typhoon and cold air, and heavy rainfall occurred in some places.
With Rosa away, from today, the rainfall in most parts of Zhejiang will gradually stop and turn cloudy.
According to the forecast of the Provincial Meteorological Observatory, as cold air will control most of Zhejiang today and tomorrow, the temperature in the whole province will drop by 4-6℃. For example, the lowest temperature in northern Zhejiang 16- 18℃ will make you feel colder in the morning and evening.
