How did Typhoon Plum Blossom come from?

The personality of typhoon plum blossom is as tenacious as its name.

On the evening of September 14, Typhoon Meihua just landed in Zhoushan, Zhejiang Province, crossed Hangzhou Bay overnight and landed in Fengxian, Shanghai in the early morning, only four hours before and after. Since then, "Meihua" landed in Shandong Peninsula around 0: 00 on September 16, and landed in China for the fourth time on September 16/2: 40.

Affected by "Plum Blossom", the wind and rain in Shandong Peninsula, Liaoning, Jilin and other places increased significantly on June 6, Qingdao and Yantai suffered heavy rain, and even extreme precipitation occurred in Fushan, Qixia and Penglai. In addition, gusts of 8 ~ 9 and local 10 ~ 12 have appeared in Shandong Peninsula and other places.

Looking at the life history of "Meihua", it survived for 8 days, not only with strong vitality, but also set a number of records in the typhoon field. Wang, a meteorologist of China Weather Network, said that Meihua is not only the strongest typhoon that landed in Shanghai and the latest typhoon that landed in Shandong since 1950, but also the first typhoon that landed in Liaoning since 2000 and the third typhoon that landed in China for four times since 1950. It was Typhoon Yang Xi before.

The landing sites of the first four typhoons in China were all concentrated in the south, and the landing site of typhoon Meihua was obviously northward, setting a new record for the northernmost landing site of typhoon in autumn.

Why can Typhoon Meihua come out of the unique path of landing in China four times in autumn? Wang's analysis is mainly due to two aspects: time and place. First of all, the high sea temperature in September is conducive to the development of typhoons, and the typhoon "Nanmadu" gave "Meihua" a lot of water vapor support, making it survive longer. Secondly, the subtropical high has shrunk eastward recently, and the north lacks cold air with the strength to compete with typhoons. Under the guidance of subtropical high, "Meihua" has been heading north along the coastline. In addition, China's coastline is long and curved, and typhoons are easy to land many times when they travel along the coast.

The gift of typhoon

In the early morning of September 16, Typhoon Meihua landed on the coast of Qingdao, Shandong Province, bringing violent storms. After the typhoon crossed the border, the beach of Navy Park in Huangdao District of Qingdao ebbed sharply, leaving a lot of seafood on the beach. The citizens came to catch the sea with buckets.

As can be seen from the video taken by netizens, the citizens who came to catch the sea did not leave with empty barrels. Mr. Hu, the video shooter, said that some of the seafood on the scene was farmed and some were in the sea. "They were all washed to the shore. When the tide ebbed, the locals came to pick up seafood."

As you can see in the video, there are many seafood scattered on the beach. Many people are picking up buckets and shovels. Some citizens picked up several buckets of clams, and some citizens specially drove tricycles to load seafood.

A merchant in the park said that 16 that morning, after watching the low tide, she went to catch the sea and picked up a lot of oysters and snails. "Someone took a few buckets and went back to cook." The merchant said that from 9: 00 am to 2: 00 pm that day, people came to the beach to catch the sea in an endless stream. By 3: 00 pm, many vehicles stopped near the park.

Ms. Tong is one of Qingdao citizens who went to the Navy Park to catch the sea after hearing the news. She arrived at the Navy Park around noon 1. The sea goods on the beach are not as rich as in the morning, but there are still many people. "There must be more than 200 people." Ms. Tong picked up more than half a barrel of giant mussels, and there were still many people on the beach when she left.

Netizens in the comment area have expressed envy, and at the same time, many fellow villagers from Shandong Peninsula have come to Versailles:

@ General Ai: Locals: This is not a festival!

@ Bai Jingjing: I feel uncomfortable looking at the crab I just bought.

@Kaiwi

: it is not recommended to answer it because it is not necessary to answer it.

@ Su Xia: Our Yantai is even worse, scraping sea intestines several times a year.

@ Nothing _ Wei: What typhoon was supposed to send fresh air?

@ 吆吆吆吆吆吆吆吆吆吆吆吆吆吆吆吆吆吆吆吆吆吆吆吆吆

@ A Rabbit Ear: Interviewer: Why do you want to work in Qingdao? Me: Because typhoons will blow seafood to the beach.

@ Jingjing Jingjing: Meihua: It's not easy to come, and there's nothing to bring. I'll bring you some specialties.

In fact, after the typhoon, the thing of "dropping" seafood in the sky happened more than once in Shandong. 20 19 After a typhoon crossed the border, pieces of seaweed were blown ashore on the beach near Haiyun Square in Laishan, Yantai. The scene was spectacular and attracted many citizens to watch.

After 20 19 typhoon "Lichima" transited Qingdao, oysters, conchs and clams appeared on the local coast of Qingdao for several kilometers, and the foodies "carried them home".

Why "detour" Jinan?

In the early morning of 15, due to the influence of plum blossoms, there was rain in Jinan, but it was much smaller than the "heavy rain in the whole city and local heavy rain" predicted before. There is a general light rain in the city, and the typhoon path is more eastward. So why did Meihua go astray?

It is understood that typhoon "Meihua" was affected by two typhoons at sea, and the subtropical high was weak to the east, which led to the adjustment of the overall moving path of "Meihua" to the east.

At the same time, it is also affected by ground friction and cold air on the north side after landing, and its intensity will be weakened, which will also affect the whole moving path.

At least five typhoons land in China every year.

Or late or leave early, typhoons happen every year, never absent.

Reporters from Shandong Business Daily and Subao News Network found that in addition to this year's typhoon landing, at least five typhoons landed in China every year, with 20 18 at the most, and 1 1 typhoons landed in China all year round.

The typhoon has crossed the border, and the internet memory caused by the typhoon is still there. 20 18 in order to cope with the arrival of typhoon mangosteen, all kinds of strange tape window sealing styles spread all over the network.

August 20 18, 12 "lark", 14 "Capricorn" and 18 "Wambia" visited China one after another and attacked East China.

According to the China Meteorological Observatory, in 20 18, there was a "four-whirl dance" in the western Pacific Ocean, which was the residual depression of Typhoon Capricorn 14, Typhoon Lippi 15, Typhoon Bebijia 16 and Typhoon 65438.

Preference landed in July and August.

Meteorologists call typhoons "tropical cyclones" more strictly. The National Standard for Tropical Cyclone Grades (GB/T19201-2006) classifies tropical cyclones into six grades: tropical depression, tropical storm, strong tropical storm, typhoon, strong typhoon and super typhoon. The typhoon we usually talk about is actually the common name of tropical cyclone whose intensity reaches the level of tropical storm.

However, only tropical cyclones with tropical low pressure will set off big waves on the sea surface, making it difficult for pedestrians to walk on land. Higher tropical storms can already break branches and make waves roll.

Statistics show that typhoons that landed in China in recent ten years were mostly tropical storms (28.8%), and typhoons and strong typhoons accounted for about 20%. Scary super typhoons are rare, accounting for only 6.8%.

July and August are often the most frequent times for typhoons to land. According to media reports, 36.6% of typhoons landed in China in August, and 27.7% in July. The remaining quarter of typhoons landed in June at the earliest or arrived late in September and June.

It is worth mentioning that in July 2020, the typhoon that landed on time in previous years was "absent" collectively, and coastal cities rarely spent the first calm July in 7 1 year.

How fierce is the autumn typhoon?

Although summer is the most active season for typhoons, it is also the most disaster-prone season for typhoons. But in autumn, the power and influence of typhoons should not be underestimated, and many "malicious characters" are often autumn typhoons.

There is no strict definition of autumn typhoon in meteorology. Generally, typhoons generated in June-August are called summer typhoons, and typhoons generated in September-165438+1October are called autumn typhoons.

Super typhoon is very prone to occur in autumn, which is related to the warming of seawater temperature. During the transition from summer to autumn, the sun moves from north to south, which warms the sea and helps the ocean accumulate more heat, thus providing more energy for typhoons. For example, Typhoon Mangosteen, No.22 in 2065438+2008, caused great damage and serious impact on South China. Mangosteen is so strong because the seawater temperature in the sea area it passes through is basically above 30℃, and the high seawater temperature provides sufficient energy for its development and growth.

The influence of typhoon

Because of its destructiveness, most of our impressions of typhoons remain that it will bring us disasters, but in fact typhoons bring us more than just disasters. The benefits brought by typhoon are as follows: 1. The abundant precipitation accompanied by typhoon brought a lot of fresh water to coastal areas, which improved the local fresh water supply; 2. Eliminate tropical and subtropical heat. Without a typhoon, the tropics will be hotter, the frigid zone will be colder, and the livable temperate zone will disappear. The huge heat energy flow keeps the earth in thermal balance.

The rainfall brought by typhoon Meihua eased the meteorological drought in southern Jiangsu, Shanghai, northern Zhejiang and southern Anhui. Shanghai, Zhejiang, Jiangsu and Anhui * * * increased water resources11300 million cubic meters, and the water level in Taihu Lake rose by about 0. 1 meter. In addition, the concentrations of PM2.5 and PM 10 in East China decreased significantly, and the air quality improved.

The provinces most likely to "trigger" typhoons

Among the seven coastal provinces in China, Guangdong has the longest mainland coastline. Among the seven coastal provinces, Guangdong's mainland coastline is 4114.3km long, ranking first in China, accounting for about 1/4 of Chinese mainland's total coastline. The long coastline determines that Guangdong is easy to attract typhoons. In the number of typhoons that landed in China's provinces in recent ten years, Guangdong ranked first with 33 times, far exceeding Fujian and Hainan provinces' 17 times.

Children who grew up in Guangdong, especially Zhanjiang, have been notified that classes will be suspended due to the typhoon. Among the eight cities and counties where typhoons landed in Guangdong Province in recent ten years, Zhanjiang is the only city and county where the number of typhoon landings has reached double digits. From the vertical perspective of years, in the past decade, typhoons landed in Zhanjiang in all years except 2020.

Although typhoons can be predicted by accurate data analysis, there are too many unpredictable factors in the typhoon path. Typhoons are ruthless. There is nothing wrong with taking precautions before they come.

Strange typhoon name

Every time a typhoon comes, the meteorological department will give it a strange name. For example: Leishma, Liu Yang, etc. These names seem to be irregular and somewhat random in style. So, how did these names come from?

It turns out that before June 65438+1 October1in 2000, the name of the same typhoon was not uniform all over the world, which brought great inconvenience to the broadcasting or dissemination of news. During 1997, the World Meteorological Organization held a meeting in Hongkong, China, at which it was decided that typhoons in the northwest Pacific and the South China Sea should be named in Asian style. As a result, 14 member countries and regions, including Chinese mainland, Hongkong, China and Chinese mainland, each provided 10 typhoon names. Thus, the name 140 typhoon was born. Then make a watch and recycle it year after year.

It is worth noting that when a typhoon has caused major disasters to one or more countries and regions, the member countries that have suffered losses can apply to the World Meteorological Organization for permanent removal of the typhoon. For example, in 2005, Typhoon Wang Long 19, Typhoon Haiyan/20 13 and Typhoon Moranti/20 16, which caused great losses to China, have been officially removed from the list because of their great destructive power. Another example is the typhoon durian at the end of 2006. From 20 13, the name of typhoon durian was changed to mangosteen.
