Three typhoons hit the northeast half! Why does this typhoon "love" the Northeast?

I believe that friends who have paid attention to the latest news of typhoons in recent months have found that typhoons seem to be a bit frequent this year, just like Typhoon No.9 just left and Typhoon Poseidon 10 came again. It is understood that the northeast has been hit by three typhoons in half a month. Why?

The Central Meteorological Observatory continued to issue a typhoon blue warning at 6 o'clock today.

It is estimated that there will be heavy rains in eastern Liaoning, central and eastern Jilin and eastern Heilongjiang from 8: 00 on the 7th to 8: 00 on the 8th, among which there will be heavy rains in eastern Jilin.

It is expected that the afternoon of the 7th to the day of the 8th will be the strongest storm period in Northeast China.

Affected by typhoon Poseidon, there was a strong wind of 6-8 in the eastern sea of China from south to north from September 6 to 9, among which the wind in the eastern sea of East China Sea was 9- 1 1, and the wind in the sea near the typhoon center could reach 12- 16.

The northeast was hit by a typhoon within half a month, which is the first time in history.

Experts from China Meteorological Bureau said that Typhoon Poseidon will once again affect Northeast China, which is the first time in history that three typhoons have continuously affected Northeast China within half a month.

In the past ten days, Typhoon No.8 Bawei and Typhoon No.9 Mesak have successively affected the Northeast.

There have been 7 ~ 8 gusts in Jilin and Heilongjiang; The daily rainfall of 49 national observation stations in Jilin and Heilongjiang exceeded the historical extreme in September.

At present, the precipitation in Northeast China is more than 1 times than normal, and it is more than 4 times in southern Heilongjiang and central and western Jilin.

Why does this year's typhoon "love" the Northeast?

According to the statistics of China Meteorological Bureau, from 1949 to 20 19, there were 189 typhoons landing in Guangdong, and there were frequent typhoons in Taiwan Province, Fujian and Hainan, but only a handful of typhoons landed in Northeast China.

Compared with typhoon landing, Northeast China is more vulnerable to "second-hand typhoon". According to historical data, there are 1.2 typhoons affecting Northeast China every year on average.

However, this year's typhoon seems to be more "partial" to the northeast, and it went north one after another. First, "Bawei" and "Mesak" came, and then "Poseidon" came to join in the fun.

Experts from the China Meteorological Bureau said that this year's typhoon "love" the Northeast was just a "forced move" under the large-scale circulation.

The trend of typhoon will be influenced by subtropical high, westerly ridge, typhoon internal force, high-rise system, double typhoons and other factors, of which subtropical high is the most decisive.

Previously, "Bawei" and "Mesak" were both guided by subtropical high, which brought strong wind and rain to Northeast China. Now Poseidon is going through a similar arrangement.

Meteorologists warned that the wind and rain impact brought by typhoon Poseidon is highly superimposed with the previous Mesak, which will further aggravate the disaster:

The risks of farmland waterlogging and crop lodging in central and eastern Heilongjiang and central and eastern Jilin are high, so it is necessary to strengthen management to prevent adverse effects on crops such as corn, rice and soybeans, protected agriculture and economic fruits. The public should guard against floods in small and medium-sized rivers and waterlogging in urban and rural areas, and strengthen the prevention of secondary disasters such as mountain torrents, landslides and mudslides; Poseidon is currently at the super typhoon level, with strong wind and rain at sea. In the eastern waters of China, it is necessary to guard against the adverse effects of strong winds on ship navigation, offshore platforms, fisheries and coastal aquaculture.
