Chinanews.com, Beijing, August 27. Since its inception on August 22, this year's No. 8 typhoon "Bahwe" has continued to grow and move northward. According to forecasts, "Bavi" will land on the coast of North Ping'an Road in North Korea from Zhuanghe City in Liaoning Province on the morning of the 27th. The heavy storms and rains that follow the typhoon will affect agriculture and rivers in Northeast my country. The Central Meteorological Observatory also issued this year's first typhoon red warning.

"Bavi" all the way to the north is approaching Liaoning's first typhoon red warning issued this year
The strength of this year's No. 8 typhoon "Bahwe" should not be underestimated. Since its formation, it has been going all the way to the north and its intensity has continued to increase, and it has reached the strong typhoon level.
At 5 pm on the 26th, its center was located in the southern part of the Yellow Sea, about 610 kilometers south of the border between China and North Korea. The maximum wind force near the center was 14 (45 m/s). The Central Meteorological Observatory predicts that Bavi will move northward at a speed of about 30 kilometers per hour. The intensity will weaken on the morning of the 27th. It will land on the coast from Zhuanghe City, Liaoning Province, China to North Ping'an Road in North Korea. It gradually shifted from north to east to northeast, passing through the three northeast provinces, and its intensity gradually weakened.

Affected by this, there were heavy rainstorms in the southeast of Liaoning, central Heilongjiang and central Shandong from the 26th to the 28th. The accumulated rainfall in southeastern Liaoning, western Jilin, central Heilongjiang, and central Shandong is 80-120 mm, and the coastal areas of southeastern Liaoning are 150-200 mm.
In addition, there are generally 6 to 8 gusts on land in the northeast region, 9 to 10 gusts in eastern Liaoning and southeastern Jilin, and 12 to 13 strong winds at the typhoon landing site and nearby seas.
The National Ocean Forecasting Station issued an orange wave warning at 08:00 on August 26: It is expected that from noon on August 26 to noon on August 27, there will be a wave of 8 to 12 meters in the Yellow Sea to the swell area, and a giant wave of 4 to 6 meters will appear in the northern part of the East China Sea. When the wave reaches the high wave area, the offshore wave warning level is orange.
At the briefing on "Bavi" on the 26th, the chief forecaster of the Central Meteorological Observatory Gao Shuanzhu said that it is unlikely that "Bavi" will land at a strong typhoon level, and the typhoon level (typhoon level, 12-13 level, 33 -38 m/s).
Although the intensity weakened during landfall, according to predictions, "Bahwe" may still become the strongest typhoon that has landed in this area since 1949. You must know that the last typhoon that landed in the northeast with a tropical storm intensity was also traced back to Typhoon No. 10 in 1964, "Hailun". The maximum wind force at the center was level 9, and the wind speed reached 23 meters per second.
The Central Meteorological Observatory issued a typhoon red warning at 18:00 on August 26. This is also the first typhoon red warning this year. The China Meteorological Administration has entered a level II emergency response state.

Typhoon going north is more prone to disasters. Agriculture, flood prevention requires high alert
Although the intensity of a typhoon will weaken from a strong typhoon to a typhoon when it makes landfall, as the strongest typhoon potentially landed in the northeast, the arrival of "Bahwe" is bound to have varying degrees of impact on agricultural production and flood control.
At present, corn, soybeans, rice and other autumn harvest crops in the Northeast have entered a critical stage of yield formation, and typhoons will bring strong wind and rain. Guo Anhong, chief forecaster of the Central Meteorological Observatory, reminded that we must closely guard against waterlogging in farmland and the possibility of wind and rain. The resulting crop lodging will have an adverse effect on the later production, and we must take precautions.
Compared with China's southeast coast, the northeast region has fewer direct typhoons, and typhoons landing north are more prone to disasters. Zhang Juan, a meteorological analyst at China Weather.com, said that this is because, on the one hand, the northern typhoon has insufficient experience in preventing typhoons, and on the other hand, the northward typhoon encounters cold air and will trigger rare heavy rainfall.
Looking at historical data, Typhoon Bulavan, which is similar to the situation in Bavi, had a serious impact on the Northeast region, causing widespread damage to crops in the Northeast.
For the rivers in the Northeast, the heavy rainfall brought by the typhoon will directly affect most of the Songliao River Basin.
According to Gao Shuanzhu, it is preliminarily estimated that the typhoon will bring relatively large precipitation to most parts of Northeast China after it makes landfall. Based on this analysis, the rainfall in the Hulan section and downstream of the Songhua River will reach 65-90 mm from the 26th to the 28th. , The surface rainfall of the second Songhua River will be 40-50 mm, and the surface rainfall of the Liaohe River Basin will be 30-50 mm. The water level of the above-mentioned rivers will generally rise significantly.

Increase the response level and rush to harvest crops and many departments enter the state of war
"Bavi" is coming fiercely. In the face of various situations that may occur, many departments have actively responded, issued early warnings and made arrangements.
The National General Defense Agency has upgraded the emergency response of flood prevention and typhoon prevention from level IV to level III at 12 o'clock on August 26. It requires relevant areas to attach great importance to typhoon defense work, closely monitor the development of typhoon "Bavi", and strengthen the weather and water conditions. Forecast and early warning, strengthen the prevention and response work of small and medium river floods, mountain torrents, geological disasters, and urban waterlogging, resolutely transfer personnel from dangerous areas, and prepare for emergency rescue.
According to the Ministry of Emergency Management, the fire rescue teams of Shandong, Liaoning, and Jilin provinces have entered a state of battle, mobilizing a total of 22,409 firefighting officers and fighters for 24-hour combat readiness, and organized 1,970 water rescue backbones, 329 boats, and 47 front At the standby point, we will make every effort to prepare for emergency rescue before the landing of Typhoon No. 8 "Bavi".
Due to the heavy rainfall caused by the typhoon affecting most areas of the Songliao River Basin, the Songliao Committee of the Ministry of Water Resources launched a level IV emergency response to flood and drought disaster prevention on the 25th: It is expected to be affected by the high-altitude cold vortex and Typhoon No. 8 on August 26-29. The northward movement of “Bahwe” is jointly affected. There will be a heavy rainstorm from south to north in the basin, and the main rivers will experience obvious flooding process. Some medium and small rivers in the rainstorm area may have floods above warning level.
In response to the possible impact of "Bavi" on agriculture in Northeast China, on the 25th, the Ministry of Agriculture and Rural Affairs urgently deployed the defense of Typhoon No. 8 "Bavi", requiring agricultural and rural departments in Liaoning, Jilin, Heilongjiang, Inner Mongolia, Shandong and other places to implement it. Various defensive measures should be taken to immediately mobilize fishing boats and aquaculture personnel operating in relevant sea areas to return to the port or to avoid wind and waves as soon as possible.
In addition, timely reinforcement and maintenance of fishing port facilities and dams, and good protection of breeding facilities. Organize farmers to rush to harvest mature crops, and conduct a comprehensive inspection and reinforcement of fruit trees, greenhouse facilities, and livestock and poultry pens. Clean and dredge field ditches and livestock farm drainage systems in time to prevent large-scale waterlogging.

Rare typhoon "first-hand" landing in the three northeastern provinces proactively respond
It has always been heard that typhoons make landfall on the southeast coast. Is it rare for "Bavi" to make landfall on the northeast?
Based on past data, 13 of the typhoons (including tropical depressions) that landed in China from 1949 to 2020 landed in the northeast, but there have been no typhoons landed in the northeast in the past 15 years from 2005 to the present. Typhoon Maisha made landfall in Dalian, Liaoning for the second time on August 9, 2005.
Generally speaking, typhoons heading north are mostly “second-hand” or “third-hand”. This is because they go northward and the sea temperature gradually decreases. When they reach the northeast, their energy is basically exhausted, and the intensity of landfall is generally tropical storm level. , Some can reach severe tropical storm level. Therefore, it is still relatively rare if "Bavi" landed directly in Liaoning at a typhoon level.
In the face of this possibly the strongest typhoon that has landed in the Northeast in more than 70 years, the three provinces of Heilongjiang, Jilin and Liaoning have already made plans.
According to the Heilongjiang Meteorological Bureau, at 11:30 on the 26th, Heilongjiang Province initiated a Grade IV emergency response to meteorological disasters (heavy rain, strong wind). It is expected that from August 27th to 28th, there will be an obvious wind and rain in Heilongjiang from the southwest to the northeast. The afternoon to night on the 27th will be the strongest period of wind and rain.
On the evening of the 26th, the peripheral cloud system of Typhoon "Bavi" had begun to affect the southeastern part of Jilin Province. As of 17:00 on the 26th, there have been 7 heavy rains and 28 moderate rains in the province, with the maximum rainfall of 47.9 mm. In view of the research and evaluation of "Bavi", the Jilin Provincial Meteorological Bureau has upgraded its emergency response to major meteorological disasters (typhoons) from level III to level II on the afternoon of the 26th.
In order to do a good job in the prevention of typhoons, the Liaoning Provincial Flood Control and Drought Relief Headquarters decided to issue a typhoon orange warning from 10 o'clock on August 26, and raise the emergency response to typhoon prevention to level 2. In addition, it issued notices and requirements to effectively fulfill the responsibilities of flood prevention and typhoon prevention; stop indoor and outdoor large-scale gatherings, suspension of classes, and suspension of business (except for special industries); in order to cope with this extreme weather process, Shenyang City requires the city’s agencies, enterprises and institutions (except necessary (Besides leaving work on time) On August 26, the end of work time will be advanced to 15:00, and schools, holiday tutoring classes, and kindergartens will be suspended at 15:30; starting at 15:00 on the 26th, night markets and outdoor tourist attractions will be closed, and construction sites will stop construction.
