In the late days of the national day “golden week”, many places are still immersed in holiday pleasures, but the citizens of yu yao city in zhejiang province were caught in a sudden storm. On 7 october, typhoon fitz 23 landed in fujian, but brought a hundred-year-old strong precipitation to yuya, far from zhedong. "in two days, almost 68 west lake waters fell on yu yao." this storm has been described by secretary mao hongfang of yu yao city。
The rainfall brought by “fit” to yu yao amounted to 499. 9 mm. In the heavy rains, 70 per cent of this small town of gangnam, with a population of 1. 3 million, was flooded and once turned into a “water town”. Water and electricity outages in the city, interruptions in communications, paralysis of traffic, and damage to millions of people amounting to $6,233 million。
Why did the strong typhoon that landed far from fujian leave ningbokyu yao, in zhedong, the “wounded”
“the twin typhoons, cold air support, are the main cause of this historically rare and powerful precipitation.” the chief forecaster of ningbo's weather station, yuko, said. During the “fit” period, its eastern sea, danas, also existed, with two typhoons having a recent distance of 1,200 km, the combined effect of the two typhoons and the spread of the colder air in the north affecting the “fit” mobile path, extending the duration of precipitation and increasing the intensity of rainfall, resulting in a marked departure of the strong rainfall centres from the main typhoon cloud area。
In addition, yu yao is located in the 4m mountain region, where the mountain range lifts the typhoon cloud, and the “north-west” route has the greatest rainfall in ningbo. At the same time, yu yao, located on the outskirts of yaojiang plain, is at the bottom of the basin as a result of the combined effects of floods in the san francisco region of the south and the catchment water in the north-west. According to the local population, the territory of the yao river is higher than the urban area, while in the north ningpo is higher than in yu yao, who is in a natural, two high and low geographic position。
The “fit” landing time coincided with the astronomical period, culminating in poor drainage of the yao river, causing severe internal flooding. “the water level of yuya exceeds the alert level of 1. 56 m to 5. 33 m.” mao hongfang was unable to speak in the media。
Information from the national climate centre also confirms that some of the tide stations in the zhejiang have exceeded red alerts as a result of storm surges ranging from 60 to 220 cm in shanghai, zhejiang and fujian coasts. Although the “fit” centre landed in fujian, its outer winds, rains and tides were intense and its impact on the zhejiang disaster was significantly higher than in fujian。
In the face of this rare storm, the emergency system of the government of yu yao was questioned. “it is even more important for governments to improve the corresponding emergency response capacity so that the plan is truly effective.” zhejiang university, faculty of public administration, professor of hu kagen。
In addition to this, it is argued that in the face of the catastrophe, in addition to the government's emergency response, social forces should be more broadly involved. The floods caused by the heavy rains in yuya have not seen more social organizations involved in the rescue, and the people's ability to save themselves from the disaster is still inadequate. These are also important elements that should be integrated into disaster relief systems。
