At around 19:50 on July 25, Typhoon "Gemei", the third typhoon of this year, made landfall on the coast of Xiuyu District, Putian City, Fujian Province. How far does it travel and how powerful is it? How long will it last? Which areas will be affected by the inland? When the critical period of flood control is superimposed on the active period of typhoons, how to prevent and respond to a more complex and severe situation? "News 1+1" common concern: Typhoon "Gemei" is coming, how to strengthen the response?
After landing, where will "Gemei" go next?
Dong Lin, chief forecaster of the Central Meteorological Observatory: At around 19:50 on July 25, Typhoon "Gemei" made landfall along the coast of Xiuyu District, Putian, Fujian Province.
In terms of future travel path, after Typhoon "Gemei" makes landfall in Fujian, it will gradually move to the northwest, pass through Fujian, enter Jiangxi, and then go to Anhui, possibly Henan, and even move to the north. Therefore, on the whole, its impact on the inland areas is still relatively large, and it is gradually weakening in the process.
How similar are Gemei and Doksuri?
Dong Lin, Chief Forecaster of the Central Meteorological Observatory: After seeing the path of Typhoon Gemei after landfall, many people will compare it with last year's Doksuri, because it also goes deep inland and goes north. But in fact, there are some differences between "Gemei" and "Dussuri", such as the intensity of their landing, "Dussuri" is stronger.
In addition, there is a very different place, looking at the atmospheric circulation of Typhoon No. 3 "Gemei" as it travels northward in the next few days. We can see that the subtropical high is in a vertical formation, which means that "Gemei" can pass through these areas in the north relatively quickly, and it is also going north, and "Gemei" is moving much faster than "Dusuri".
There is a strong high-pressure dam to the north of "Doksuri", which means that their "situation field" is very different. "Doksuri" stays for a long time, but it is possible that "Gemei" can move faster than it, and may not stay in a certain place for a long time, and it may rain for a long time in a certain place, which may be the kind of rain that passes by.
Downgraded to typhoon level at landfall, has the impact of wind and rain passed?
Dong Lin, Chief Forecaster of the Central Meteorological Observatory: We can see from the radar echo map of Typhoon Gemei that the scale of the typhoon itself is relatively large, and it is directly connected to the southwest monsoon.
In other words, even if there is no typhoon, the monsoon pushes up directly, and the impact of wind and rain is very large. The combination of a typhoon and the monsoon does not mean that its effects will end after landfall, but more than half of the effects have not even begun after landfall.
We can also see from the larger-scale satellite cloud images that not only is there a monsoon connected to the south side of Typhoon Gemei's main body, but there is also a steady stream of southwest monsoons behind it, so the duration of this impact is actually quite long. As Typhoon Gemei moves northward, there will be constant wind and rain on both the east and south sides of its path.
What is an "all-chief joint consultation"?
Recently, the meteorological department has a new form of work called "all-chief joint consultation", which can play a role in analysing weather trends and risks?
Dong Lin, Chief Forecaster of the Central Meteorological Observatory: I think there is a very vivid analogy, people may be familiar with expert outpatient clinics and expert collective consultations, and the collective consultations of our forecasters are a bit similar.
In his daily work, the chief forecaster on duty today may not have thought about it well, especially in the face of particularly difficult and large weather processes. Last year, we launched the all-chief joint consultation, which means that whether you are on duty or not, experienced forecasters will come over to discuss and analyze weather trends and make multi-angle judgments, so as to form a more accurate conclusion.
What is the situation of flood control?
Kang Bin, Director of the Pearl River Taihu Lake Division of the Department of Flood Control and Drought Relief of the Ministry of Emergency Management: The National Defense Office and the Ministry of Emergency Management now insist on holding two meetings every day, and when the typhoon made landfall at 19:50, we immediately dispatched Fujian and Zhejiang.
At present, heavy to extremely heavy rains have fallen in the eastern part of Fujian and the southeastern part of Zhejiang, and the two provinces have not received any information on major disasters, dangers, or casualties, except for some trees that have fallen and a small number of townships and towns have had their power supply and communications affected.
Judging from the future forecast, the impact of the typhoon is mainly rain, which may last until July 31, and geographically through more than a dozen provinces such as Fujian, Jiangxi, and Jilin from south to north, affecting the Pearl River, Yangtze River, Songhua River and other seven major river basins.
Typhoons and floods, how to deal with them with all our might?
Kang Bin, Director of the Pearl River Taihu Lake Division of the Department of Flood Control and Drought Relief of the Ministry of Emergency Management: After the typhoon landed, the typhoon prevention work changed from sea to land, and there are four main tasks:
(1) Continue to do a good job in social shutdown and control, so that urban and rural areas can be calmed down. Specifically, we must implement relevant measures, stop outdoor group activities, suspend work, business, and operation, and do a good job in the management and control of some wading bridges and underground spaces.
(2) Do a good job in the transfer of personnel to avoid danger, so that the masses can hide. We must ensure that the people in the hidden danger points and dangerous areas of flash floods and geological disasters, as well as low-lying and flood-prone areas, and dilapidated old houses can be moved out in a timely manner, and they should be resettled to ensure their safety.
(3) Prepare emergency rescue teams and materials and equipment to make emergency response faster. For example, the professional forces of various industry departments such as transportation, electricity, communications, and drainage, as well as our fire rescue team and social emergency response forces, can quickly rescue and recover quickly after the disaster after an emergency, so as to minimize disaster losses.
(4) Finally, we need to publish the rain and flood conditions and work dynamics on a rolling basis, so that the information can run. It can allow the masses to hear the voice of our government, the tips for avoiding danger, and the early warning of relevant departments.
