This summer's first direct typhoon in china, typhoon no. 6, hit。
Heavy typhoons or supertyphoones that landed in zhejiang in july are extremely rare and it is likely that typhoon fireworks will become a record typhoon。
The deputy director of the ningbo meteorological department, bau yue, analysed the “pyrotechnics” as having the characteristics of slow movement, abundant water, strong intensity, long impact periods and three encounters of “wind, rain, tides” and asked for the highest level of ultra-conventional defence。
The experts recommend that citizens ' friends spend two break days at home to minimize going out, keep their doors and windows closed, collect high-altitude items, such as flower pots, and check for the safety of facilities such as electrical circuits, gas, etc. In their homes; park their vehicles as far as possible at high points or in areas where water is not easy to accumulate, avoid bridges and guard against flooding in their cities; leave their homes far from rivers, lakes, coasts and areas where water is flooded, and do not go to the seaside to catch wind; and stay away from temporary buildings, trees, billboards, etc. That may collapse or fall. Part of the population living in mountainous, coastal or low-lying sections of the road is requested to follow the direction required and be transferred to disaster shelters in a timely manner。
Why are fireworks so strong
Bauer explained that the great energy of the typhoon came from warming the ocean. “pyrotechnics” pass through the region with high sea temperatures, wide cloud bands and abundant water vapours, providing a constant “energy stick” to the pyrotechnics. Because of the lack of a clear guiding stream of air with “pyrotechnics”, the lost “pyrotechnics” move very slowly at sea, which also provides ample time for the “pyrotechnics” to absorb energy on a continuous basis and for the excess nutrients to develop into a full and powerful typhoon。
In addition, “pyrotechnics” carry sufficient water vapours and are known as “water and cargo typhoons”. During the “pyrotechnics” northward period, two tropical south-west monsoons in the indian ocean, the south china sea and a sub-tropical south-east monsoon in the pacific ocean, each with huge amounts of water, converged at the site of the “pyrotechnics” — a collection of thousands of favors — and the “pyrotechnics” will continue to pour heavy rain from their arrival。

Why is the pyrotechnic landing site elusive
According to baue-jian, the direction of typhoons is largely determined by the combination of surrounding systems such as sub-tropical high pressure, other nearby typhoons and the typhoons themselves. In mid-july, the subtropical high-pressure north jumped to the sea of japan, and a series of tropical cyclones emerged in the north-west pacific tropical irradiation belt。
“pyrotechnic” paths affect numerous systems, with subtropical highs on the north side, low cut-off vortex on the north-west side leading to heavy rain in henan, typhoon “chapaka”, which landed in guangdong and travelled around the sea, and tropical disturbance systems on the east, which may have developed into the next typhoon, affecting the path of “pyrotechnics”. The forces pulled saws, turning the pyrotechnics around and making them elusive. At the moment, “pyrotechnics” are most likely to land on the central north coast of my province between the afternoons of 25 and the morning of 26。
What will be the impact of “pyrotechnics” on ningbo
According to a study conducted by baue-jian, this rainfall could break historical extremes. Whether or not they land in ningbo, the city will be hit by fireworks. Because of the slow pace of “pyrotechnics” movement in the early stages, the later stages may even continue to stagnate along our province's coast or inland, with excessive waiting times, and the cumulative rainfall of the process may break historical extremes。
According to nimbau, continuous heavy rains are expected to exceed five days. From 24 to 26, there will be heavy rains in our city to heavy rains, and from 27 to 28 days to heavy rains。
Second, the wind, rain and tide meet three times. Typhoon, as a tropical low-pressure system, has greater wind power in areas closer to the typhoon eye. Ningbo is currently within the maximum probability of landing by the typhoon and will be hit by severe storms. Large winds of 12 to 15 classes are projected on the coastal surface, with typhoons passing through 15 to 17 classes, and large winds of 8 to 13 classes in the inland areas from 24 to 26 days. At the same time, at a time of great astronomical tides, sea-surface winds are enormous, with enormous impacts on coastal areas and fishing vessels. Moreover, the concentration and persistence of rainfall and the rising sea level caused by high tides have placed higher demands on urban drainage systems。
Journalists were informed that the municipal meteorological department was fully engaged in the early warning of typhoon monitoring forecasts and that it had today launched a secondary emergency response to the major meteorological disasters (typhoon) operations service. At present, the municipal weather station has issued typhoon alerts and typhoon yellow alerts, and 10 district (city) districts have issued typhoon yellow warning signals, in which yao, jiangbei, the town sea, bong and iwayama simultaneously send heavy rain orange warning signals and north lon and elephant fire alerts。
The meteorological services at the municipal and district levels quickly moved into an emergency situation, with strict implementation of a system of leadership on duty and 24-hour duty; closely monitored typhoon movements, rolling early warning of typhoon dynamics and storm impact forecasts, with a focus on strengthening early warning of precision forecasts of stormy and stormy weather in coastal and local areas; and the united municipal natural resources and planning agency encrypted disaster preparedness dynamics conference, closely monitoring the impact of typhoons and issuing joint early warning of meteorological risks of geological disasters。
As of 4 p. M. Yesterday, the municipal weather service issued a total of 21 issues of the typhoon report, comprising 8 issues of typhoon news, 7 issues of the maritime typhoon alert, 5 issues of the typhoon alert and 1 issue of the typhoon emergency alert. Twenty-five warnings were issued throughout the city. The decision-making meteorological service has been strengthened by rolling up-to-date text messages totalling more than 47,000。

How can we do “pyrotechnic” defence
1. It is not necessary to leave during the typhoon。
2. Do not take shelter in the vicinity of temporary buildings, billboards, iron towers, trees, etc., and contact the emergency and rescue services as soon as possible in case of a high-altitude crash。
3. Detachments from roadside electric tanks, pilings, wires and dangerous buildings。
4. To refrain from stopping along river-coast roads, embankments, river surges, fish ponds, reservoirs, swimming by the water, mountainsides and risk climbing。
5. People living in hazardous old houses, improvised houses, iron-coated houses, sheds and low-lying areas were evacuated to safe areas in coordination with local government arrangements。
6. Close doors and windows carefully, remove roofs, windows, flower basins in the balcony, suspensions, etc., and reinforce facilities such as outdoor air conditioning, solar water heaters, etc。
7. To keep abreast of the latest forecast early warning information issued by the weather stations and to prepare for the stations。
The most severe typhoon impact on ningbo in history
