Typhoon fireworks have been upgraded to a strong typhoon and are close to Shanghai. What should we pay attention to in Jiangsu, Zhejiang and Shanghai coastal areas?

1. At present, Typhoon Fireworks Center is located in the east of Taiwan Province Province, about 800 kilometers away from Zhoushan. At present, the instantaneous maximum wind force is 48m/s, which is slowing down.

Move to the northwest. Due to the weak steering airflow situation and the influence of 90W low-pressure system in southeast Japan (which has developed into Typhoon Nibert), smoke

Whether the flowers landed or not, and even the location of the landing point, is still confusing. But the subtropical high still controls eastern Japan.

In this area, fireworks may continue to slowly approach the coast of Zhejiang. At present, according to the cloud image and convection analysis, the eye area of typhoon fireworks is expanding, which may replace the eye wall, because the current fireworks

The core CDO (Central Miyun District) intrudes into dry air, and the outflow on the north side encounters difficulties. At present, the development is slow, but it still needs to be sustained.

Continue to observe the follow-up development, after all, it has entered the Kuroshio area.

Secondly, according to the detection of meteorological radar, the eye area of typhoon fireworks is still very large, and its core energy is currently on the south side of the eye area, and other positions are whole.

If fireworks are not easy to get along with, it can be seen that being involved in dry air has a great influence on them, but the circulation of fireworks is still huge, and the impact on Guangdong is not limited to this.

Typhoon Chapaka in the south is much bigger and its intensity should not be underestimated. The speed of typhoon fireworks is still very slow, and it is difficult to judge its real specific goal. Fujiwara effect and lack of obvious turning flow cause it to still fly.

Wandering in the east of Taiwan Province Province, there is a little convection on the west side of the eye area, but the outflow on the north side has not improved, and the convection on the south side has deepened

It's a little thick

If fireworks continue to wander and move less, it will exhaust the sea surface temperature of the ocean where they are located, and the cold water will not be conducive to its development.

With the passage of time, convective clouds are more likely to explode at night, which will be a critical period for the development of typhoon fireworks and will also

Determine with what intensity it will affect the east China coast. Fireworks are still moving at high speed in the sea area, and the heat in this sea area has been consumed by it, so typhoon smoke

The development of flowers is hindered and the strength is weakened. At present, according to its convection, the convection in the south has also weakened correspondingly, and the north is still declining.

Obviously, the convection on the spiral rain belt south of the fireworks is still relatively strong, and it will greatly increase if it can be involved in the typhoon core area.

Strong. In addition, according to the radar map, the convective decline brought by the squall line in front of the station landed sporadically (in the orange circle) and entered Zhejiang, giving some areas in Zhejiang.

This area brings short-term strong winds and heavy precipitation, so please take precautions.

Third, typhoon fireworks are still cold water pits caused by their slow moving speed. At present, the main convection of typhoon fireworks is

Has been thrown to the east, the west is broken, and the strength level has been falling all the way, but today it is time to speed up the pace. There was a typhoon last night.

The path of fireworks turns due north, so northern Zhejiang is more likely to be its landing site. At present, a large number of fireworks can be seen according to the radar map.

When the squall line lands in front of Taiwan Province, there will be windy and rainy weather in Ningbo, Taizhou and Wenzhou, Zhejiang.

At present, the speed of typhoon fireworks is gradually accelerating, but its convection is weakening, and the intensity change should be small, but it is brought by its huge clouds.

Precipitation should not be underestimated. As the subtropical high continues to retreat eastward, its main manifestation has been reduced to Alaska's South Pacific.

Therefore, if the typhoon fireworks land, they will lack the guidance of the edge of the subtropical high, and then there is a great possibility to stay in East China, which is also possible.

Pulled by the low-pressure system in the east.

Fourth, turning back to East China will cause continuous precipitation, and typhoon fireworks may also be associated with it.

Combined with the cold vortex and inverted trough precipitation in North China, it brings precipitation process to Jiangsu, Shandong and other places in China. Magnificent

The eastern region will be severely tested by heavy rain. According to the current convection of typhoon fireworks, there is strong convection in the south side after entering, but the whole core cloud area has appeared.

Tear, we can know that it has been exhausted by the lack of energy caused by the slow pace of stillness. As can be seen from the cloud picture, the spiral in the north

It is expected that the rain belt will enter Zhejiang tomorrow, and the coastal areas of Zhejiang will begin to be hit by strong winds and heavy rains tomorrow.

At present, the center of typhoon fireworks is located in the East China Sea, 465 kilometers south of Shandong Province, and its convection

The situation has obviously increased. Although its bottom scan shows that the southwest of its eye area is still relatively fragile, the smoke will increase after the moving speed is accelerated.

Flowers have begun to re-integrate, the eye area has begun to decrease, and the second strengthening of fireworks has begun. It will try its best to strengthen today and will be back soon.

At the level of strong typhoon, the coastal areas of East China should not be taken lightly. At present, the rain belt of typhoon fireworks cantilever has landed, and the radar shows Hangzhou Bay.

There have been a lot of echoes around Jinhua and other places, and the strong wind and rain will continue, and the main body of typhoon fireworks will begin to affect.

East China coast, please take precautions.

According to the forecast of many organizations, the typhoon fireworks will whirl in East China, bringing several days of heavy rainfall to East China (Zhejiang, Shanghai and Jiangsu).

Water, we must do a good job in flood control and waterlogging prevention, hoard food, charge the charging treasure and welcome fireworks. Storm surge, rainstorm and astronomical tide will bring great challenges to Zhejiang coastal areas.

When the typhoon moves to the land, due to the typhoon's strong wind and low pressure, the sea water will gather strongly in the direction of the coast and the tide level will rise sharply.

The waves quickly press against the coast, which is the typhoon storm surge. The storm surge caused by a strong typhoon can raise the coastal water level by 5 to 6 meters, which will lead to tides.

Overflow, seawalls burst and flooded towns and farmland. In addition, storm surge will also cause coastal erosion, and seawater intrusion will salinize the land.

Dvorak analyzed that the intensity of typhoon fireworks started to take off again today. Why hasn't the Central Meteorological Observatory upgraded its powerful station?

The wind level is incredible. At present, the intensity of typhoon fireworks is definitely a strong typhoon level, and convection has begun to break out in the northern region. At present, typhoons mainly

The north cantilever of the aircraft has begun to land, and the wind and rain conditions in Zhoushan and Xiangshan will be very bad. I hope you don't forget when you watch the Olympic Games.

The circulation of typhoon fireworks is really huge, and the water vapor contained in it is amazing, connecting the southwest monsoon and the northern front.

After the rain belt, the precipitation intensity is unstoppable, and the tragedy in Henan can't be performed again!

6. The structure of typhoon fireworks was cut into a bad shape. At present, according to the convection situation, it can be seen that its main convection is concentrated in the cloud.

The coastal wind and rain will strengthen after the eastern part of the regiment is close to Shanghai this afternoon and evening. Because of strong typhoon Niebert

The lack of intensity has no obvious promotion effect on typhoon fireworks, which leads to the northward movement of fireworks path. At present, the intensity of typhoon fireworks may be

The lower limit of typhoon (30-35m/s), the landing point may be from Zhoushan to Qidong coast, and it may go straight into Shanghai. Its dangerous semicircle is

Landed in the north, so the impact on Shanghai can refer to Typhoon Mai Sha.
